The field of the invention relates generally to skin care. According to several embodiments, topical formulations that show visible beneficial dermatological results are provided.
Skin care formulations, such as those for the eye and face, include for example, serums, lotions, and creams, are used for various purposes. Formulations can act as a moisturizer, provide coverage, or contain vitamins. For protection, some formulations contain a sun protection factor (SPF).
Despite the large number of cosmetic formulations for treating the eye that are on the market, there remains a need for an enhanced topical formulation that simultaneously reduces and corrects the appearance of dark circles, puffiness, fine lines, and wrinkles, provides hydration, and addresses the delicate needs of the eye area (which can be much more sensitive than other skin on the face). In one embodiment, the formulation provides significant UV protection (such as physical UVA and UVB sun protection),
In several embodiments, a 3-in-1 renewal formulation is provided that advantageously delivers both immediate and long-term results. For example, a topical formulation according to several embodiments (i) immediately brightens the eye area and corrects imperfections to reduce dark circles and puffiness for a refreshed and rested appearance, (ii) provides a chemical-free, 100% mineral sunscreen to defend against UVA/UVB rays and environmental stressors that contribute to skin aging, and (iii) restores skin health with hydration that provides support for sagging skin to enhance the eye area.
One benefit of the formulations described herein is the ability for a user to apply a formulation to achieve correction, hydration and protection in a single product rather than using multiple products. Use of a single product around the eye area is advantageous in several embodiments because application of multiple products around the eye can increase the risk of irritating the delicate eye area (based on, for example, adverse interactions of the various products, the mere act of physically touching the eye area multiple times, layering of multiple products resulting in lack of breathability or poor absorption, etc.).
Because of the delicate eye area, there is a particular need in one embodiment for an enhanced formulation that is both efficacious and suitable for delicate skin, and additionally incorporates a broad-spectrum sunscreen, without being irritating or chalky. In several embodiments, the formulations described herein comprise a sun protection factor of SPF 35 or higher. In one embodiment, mineral (chemical-free) sunscreen ingredients are provided as a defense against photoaging. In several embodiments, zinc oxide is used as a sunscreen. In some embodiments, titanium dioxide is used. In other embodiments, a combination of zinc oxide and titanium dioxide is used. In one embodiment, a clear formulation is provided in which titanium dioxide, zinc oxide and colorants are not included.
In several embodiments, the invention comprises or consists essentially of a unique topical formulation that comprises at least 3, 4, 5, 6 or all of the following (with ranges provided as % m/m, % m/v, % w/w, % w/v or % v/v of the formulation):
In one embodiment, at least 80% or 90% of the ingredients in (i)-(vii) are provided % m/m or % w/w. In several embodiments, effective (e.g., therapeutic) amounts of ingredients are included in the formulation. An effective (e.g., therapeutic) amount, in one embodiment, may be that which reduces the appearances of fine lines, puffiness, dark circles, and/or laxity after at least four weeks of twice daily use.
In some embodiments, the invention comprises a topical formulation with an SPF of at least 15 (e.g., 15, 25, 35, 50, or higher) that comprises at least four (and in one embodiment all) of the following: titanium dioxide, zinc oxide, Albizia, darutoside, Dunaliella, algin, Ascophyllum, Asparagopsis, betaine, and Tremella (including for example extracts, components or portions thereof), as well as other ingredients. In some embodiments, the darutoside is extracted from the Siegesbeckia orientalis plant. In some embodiments, a Centella extract is included, such as an asiaticoside extracted from Centella asiatica.
In some embodiments, the invention comprises a topical formulation without titanium dioxide or zinc oxide as SPF factors, wherein the formulation comprises at least four (and in one embodiment all) of the following: Albizia, darutoside, Dunaliella, algin, Ascophyllum, Asparagopsis, betaine, and Tremella (including for example extracts, components or portions thereof), as well as other ingredients. In some embodiments, the darutoside is extracted from the Siegesbeckia orientalis plant. In some embodiments, a Centella extract is included, such as an asiaticoside extracted from Centella asiatica.
In several embodiments, a topical formulation is provided that comprises water, sorbitol, Ascophyllum nodosum extract, Asparagopsis armata extract, palmitoyl tripeptide-5, panthenol, sodium hyaluronate, Dunaliella salina extract, hydrolyzed algin, sucrose, glycerin, Albizia julibrissin bark extract, darutoside, Tremella fuciformis sporocarp (silver ear mushroom) extract, betaine, xanthan gum, polysorbate 20, phenoxyethanol, ethylhexylglycerin, caprylyl glycol, and caprylhydroxamic acid.
In some embodiments, the formulation comprises at least four (and in one embodiment all) of the following: titanium dioxide, zinc oxide, Albizia julibrissin, Dunaliella salina, hydrolyzed algin, betaine, Ascophyllum nodosum, Asparagopsis armata, Centella asiatica, Siegesbeckia orientalis and Tremella fuciformis sporocarp (including for example extracts, components or portions thereof), as well as other ingredients. Such other ingredients include, but are not limited to, one or more of: water, siloxanes, triglycerides, dimethicone, glycerin, panthenol, jojoba esters, sodium hyaluronate, palmitoyltripeptide-5, pantolactone, and tocopherol. In one embodiment, neither titanium dioxide nor zinc oxide is included.
In some embodiments, several of the ingredients work synergistically. The synergism achieves a beneficial result that is more efficacious than the additive effects of the ingredients, according to some embodiments.
Many embodiments achieve at least one of the following benefits (and in some embodiments, all of the benefits): (i) immediately brightens and corrects dark circles (e.g., by providing a neutral peach tone), (ii) reduces puffiness (e.g., through use of a cooling applicator), (iii) smooths fine lines and wrinkles, (iii) protects against future sun damage, (iv) hydrates, and (v) primes skin for smooth application of eye makeup.
In some embodiments, the treated skin is re-hydrated, in which hydration is increased by 25-75% or more post treatment with the formulations described herein (within minutes or hours post treatment). In some embodiments, the appearance of wrinkles, dark circles, fine lines and/or laxity is reduced by at least 25-95% post treatment with the formulation used consistently (e.g., 1, 2 or 3 times daily) after, for example, 7, 14, 21, 28, 60 or 90 days.
In some embodiments, the formulations provided herein are concentrated and provided in a mask form to be left on the skin for at least 5, 15, 30, or 60 minutes (or as an overnight repair mask). Gentle cleansers may also include many of the ingredients of the formulations described herein and may additionally include witch hazel or other gentle toners (for toner-type cleansers) or foaming ingredients (for washes and foaming cleansers). In several embodiments, more concentrated formulations are provided for use as a spot treatment or for treatment of an area smaller than the area treated by a mask.
In some embodiments, visible reductions in the appearance of dark circles and puffiness may be observed within minutes of use of a formulation as described herein, due to, for example, a color correction pigment and/or the anti-inflammatory activity of the ingredients. A soothing or cooling sensation may be experienced by the user upon application to the skin, which may also contribute to the reduced puffiness.
In several embodiments, an SPF of least 30 (e.g., 35, 50) is used while avoiding a chalky appearance and allowing eye makeup to be applied smoothly over the treated area. This is advantageous because certain sunscreens can discolor the skin and/or provide an unsuitable surface for application of other cosmetics.
In several embodiments, the formulation is provided as a topical formulation, including but not limited to a mineral-based formulation. In several embodiments, the formulation is provided in the form of a liquid, cream, serum, or gel.
The areas of the eye to be treated include, for example, the entire orbital region, from under eye to brow, including eyelids. Although the formulations described herein are useful to treat the eye area, in some embodiments the formulations can also be used to treat other skin regions that would benefit from brightening, reduced puffiness, smoothing of fine lines and wrinkles, hydration and sun protection. For example, the nasolabial folds and marionette lines may be particularly well suited to benefit from the formulations described herein. Scars may be treated in some embodiments.
In several embodiments, the formulation is contained within an applicator with a dispensing tip. The applicator may have a metallic tip in some embodiments. The applicator may be pen or cylindrical shaped in one embodiment and the tip may be a round or oval partially flattened or curved shape to help application to the contours of the eye and other areas. For eye applications, the tip may be narrow and contoured to navigate the contours of the eye region. Larger applicators may be used for other regions on the face and body. In several embodiments, the formulation is used during or after a dermatological procedure (including but not limited to brow lifts, blepharoplasty, botulin and other neurotoxins, facials, fillers, dermabrasion, microdermabrasion, micro-needling, peels, exfoliations, suctioning, fluid delivery, acid treatments, massage, extractions, energy-based and other treatments, such as lasers, thermal, radiofrequency, light (e.g., photofacials/IPL), etc.). In some embodiments, the applicator includes fluid delivery conduits, pressure/air-based devices, and sonicators. In several embodiments, formulations may be stored and/or delivered by use of a bottle and/or dropper. In several embodiments, the dropper or other delivery device is graduated and/or indexed to deliver pre-set amounts of a formulation disclosed herein. In some embodiments, the applicator includes a paddle or contoured metallic tip to facilitate application.
In some embodiments, the formulation is contained within an applicator having a tip with a thermal conductivity configured to provide a cooling effect. In several embodiments, the invention comprises a use or method of reducing laxity, puffiness, wrinkles and/or dark circles around the eye, comprising administration, or instructing administration of a formula described herein.

In several embodiments, long lasting effects on the skin are achieved in less than 1-3 months.
Several embodiments of the invention comprise a formulation for soothing irritated skin while also reinforcing the skin's natural defenses. In some embodiments, the formulation optionally includes ingredients that provide protection against UV damage. In some embodiments, the formulation is a liquid, gel, cream or serum. Solid forms (e.g., powders) may be provided. The formulations described herein can be applied prior to or after foundation or other make-up. In some embodiments, the formulation is colorless (e.g., clear); however, in other embodiments, the formulation contains sufficient color to serve as foundation and/or color corrector (e.g., with peach undertones to balance dark areas). In some embodiments, the pH of the formulations is slightly basic, slightly acidic or neutral. In some embodiments, a pH of 3-5, 4-6, 5-7, 6-8, or ranges in between, are provided. Lower or higher pH values may also be used. In one embodiment, a clear formulation is provided in which, for example, titanium dioxide, zinc oxide and colorants are not included. In some embodiments, a clear formulation without titanium dioxide, zinc oxide or colorants is provided as a serum in which the ingredients are concentrated by at least 10-50% or 2-15x, as compared to the formulations containing titanium dioxide, zinc oxide and colorants.
According to several embodiments, the formulations described herein can be applied by an applicator, including one with a smooth metallic tip, a roller ball tip, a plastic tip, or combinations thereof. In one embodiment, the tip has a different thermal conductivity than the body of the applicator to cause a cooling effect at the tip that helps reduces puffiness. The size of the applicator tips may be configured for the region to be treated. For example, the eye area, nasolabial folds and marionette lines may be suited for a smaller tip than larger target regions. Alternatively, the formulations may be applied by hand, by sponge, by spraying, by dropper, by brush, or through use of a composition-impregnated substrate (such as silicone pads or wipes).
In some embodiments, the formulations described herein can optionally be applied by transdermal patch. In some embodiments, the formulations are absorbent (e.g., readily absorbable) such that no separate means are needed to enhance absorption. However, in alternate embodiments, one or more of massage, mechanical manipulation, energy, or vibration may be used to facilitate absorption. In some embodiments, the formulation is useful post-surgery or dermatological treatment. Further, some of the formulations described herein may be suitable for use for application under one or more skin layers (e.g., as an injectable)

Despite the large number of cosmetic formulations on the market, there remains a need for a cosmetic formulation that simultaneously reduces hyperpigmentation in a multi-modal manner and offers significant physical UVA and UVB sun protection, and optionally provides coverage (e.g., color) in a formulation that goes on smoothly and is not chalky or sticky. In many embodiments, the reduction of inflammation through the inclusion of an anti-inflammatory agent (e.g., vitamin E compounds) synergistically works with the other ingredients to counter hyperpigmentation via multiple pathways to enhance lightening and/or brightening effects.
Several embodiments of the present invention meet the need recited above. Several embodiments relate to unique skin care formulations for treating and protecting skin, including preventing further damage. Both healthy skin and damaged skin can benefit from several of the formulations described herein. Damaged skin can include skin with hyperpigmentation. Several embodiments are particularly useful for reducing specific regions of hyperpigmentation, thereby producing a brightening or lightening effect. An enhanced glow or radiance is achieved by several embodiments. Several formulations described herein are not limited to skin with hyperpigmentation. Indeed, many formulations are not only protective (for example by including a sun protection factor or SPF), but also nourish the skin, increase hydration and improve overall appearance, texture and firmness. Thus, several formulations of the invention are beneficial for skin that is aged, sun-damaged, wrinkled, lax, and/or blemished. Formulations according to several embodiments can be used anywhere on the body, and are especially beneficial for the face, neck, décolletage and hands, where hyperpigmentation and signs of aging may be particularly prominent.
In some embodiments, the invention comprises a topical formulation for treating and protecting skin in a subject, wherein the topical formulation is a liquid (such as a serum, lotion, liquid primer or cream), a gel, a spray, a powder, or a combination thereof. In some embodiments, the hyperpigmentation, brightening, and/or lightening formulations are used during or after a dermatological procedure (including but not limited to brow lifts, blepharoplasty, botulin and other neurotoxins, facials, fillers, dermabrasion, microdermabrasion, micro-needling, peels, exfoliations, suctioning, fluid delivery, acid treatments, massage, extractions, energy-based and other treatments, such as lasers, thermal, radiofrequency, light (e.g., photofacials/IPL), etc.).
In several embodiments, use of the formulations described herein reduces hyperpigmentation by about 10-100% (e.g., about 10%, 25%, 50%, 75%, 100% and ranges in between) after use. For example, significant lightening effects and improvements in pore size, fine lines, overall appearance, radiance, skin smoothness, and/or skin tone (evenness) are visible in several embodiments after 4 weeks, 8 weeks or 12 weeks. Certain improvements in skin may be visible or felt upon use or within days of use. Although specific regions of hyperpigmentation (e.g., age spots) are treated according to several embodiments, an overall lightening or brightening effect can also be achieved on skin that has no discrete regions of hyperpigmentation.
The topical formulation, in several embodiments, comprises or consists essentially of one or more anti-melanin agents (such as tyrosine inhibitors), one or more anti-inflammatory agents, and one or more sun protection agents. The anti-melanin agent(s) (such as tyrosine inhibitors) and anti-inflammatory agent(s) (such as vitamin E compounds) work synergistically together in many embodiments to counter undesired pigmentation.
In several embodiments, the formulation comprises (i) a first anti-melanin agent, (ii) a second anti-melanin agent, (iii) an anti-inflammatory agent, (iv) a sun protection agent, and (v) an optional anti-oxidant. In several embodiments, the formulation comprises about 0.05-5% of a first anti-melanin agent, about 0.005-5% of a second anti-melanin agent, about 0.05-5% of an anti-inflammatory agent, about 5-30% of a sun protection agent, and about 1-5% of an optional antioxidant, wherein the ranges are provided as % m/m, % m/v, or % v/v of the formulation. In some embodiments, the first anti-melanin agent comprises a Bidens pilosa extract, the second anti-melanin agent comprises a Rheum rhaponticum extract, the anti-inflammatory agent comprises a Vitamin E compound, the sun protection agent comprises zinc oxide and titanium dioxide offering a high sun protection factor (e.g., of SPF 30, 50 or more), and the antioxidant comprises a Thermus thermophillus ferment extract. The formulation may additionally comprise some (e.g., 1-4) or all of the following oils in some embodiments: an Elaeis guineensis oil, a Gossypium herbaceum seed oil, a Linum usitatissimum seed oil, a Citrus paradisi seed extract, and a Fusanus spicatus wood oil. In several embodiments, effective (e.g., therapeutic amounts) of ingredients are included in the formulation. An effective (e.g., therapeutic) amount, in one embodiment, may be that which reduces hyperpigmentation or uneven skin tone after at least 1-18 months (e.g., 4-12 weeks) of twice daily use.
In several embodiments, the formulation comprises a Bidens pilosa extract, an acetyl Rheum rhaponticum root extract, a Vitamin E compound, a Thermus thermophillus ferment extract, a zinc oxide, and a titanium dioxide, wherein the formulation provides a high sun protection factor of SPF 30, 50 or more. In some embodiments, the formulation comprises about 0.005-5% or about 0.05-5% Bidens pilosa, about 0.005-5% or about 0.05-5% acetyl Rheum rhaponticum root extract, about 0.05-5% Vitamin E compound, about 0.05-10%, about 5-15% zinc oxide, and about 10-15% titanium dioxide, wherein the ranges are provided as % m/m, % m/v, or % v/v of the formulation. In many embodiments, the percentages provided are % m/m or % w/w.
In several embodiments, the Rheum rhaponticum extract comprises acetyl Rheum rhaponticum root extract and the vitamin E compound comprises disodium lauriminodipropionate tocopheryl phosphates. The formulation may be a topical formulation in the form of e.g., a liquid, cream or gel, and in one embodiment is a paraben-free facial primer.
In several embodiments, a method of treating skin discoloration is provided, the method comprising identifying at least one region of a skin tissue having discoloration or an uneven tone (including but not limited to hyperpigmentation) and applying, or instructing application of, any one of the topical formulations described herein to the skin region, wherein the formulation lightens the hyperpigmentation and/or improves skin tone uniformity, as well as provides protection from ultraviolet rays,
In some embodiments of the invention, the anti-melanin agents used herein directly and/or indirectly reduce the production of melanin, degrade melanin, reduce the melanin transfer from melanocytes to keratinocytes, and/or reduce the storage of melanin. In some embodiments, anti-melanin agents are tyrosinase inhibitors that inhibit the production and/or accumulation of melanin by inhibiting tyrosinase (which facilitates melanogenesis). Tyrosinase inhibitors used in the formulations described herein include but are not limited to one or more of the following: extracts from the rhubarb family (such as Rheum rhaponticum, acetyl Rheum rhaponticum root extract), ascorbic acid, bearberry, licorice, mulberry, kojic acid, green tea (epicatechin gallate, epigallocatechin gallate and gallocatechin gallate) and acetylated hydroxystilbene. Tyrosinase inhibitors used in the formulations described herein also include but are not limited to polyphenols such as curcuminoids, flavonoids (e.g., anthocyanins, flavanols, flavanones, flavonols, flavones, isoflavones) and stilbenoids (e.g., resveratrol, pterostilbene), free radical scavengers, and copper chelators. Anti-melanin agents used in the formulations described herein include tyrosinase inhibitors, as well as other agents that are not tyrosinase inhibitors but also have an ability to reduce the production of melanin, degrade melanin and/or reduce the storage of melanin (e.g., endothelin inhibitors). In some embodiments, the anti-melanin agent is a tyrosinase inhibitor comprising a Rheum rhaponticum extract (e.g., acetyl Rheum rhaponticum root extract) and a panthenol compound (e.g., panthenyl triacetate). In some embodiments, the anti-melanin agent is acetylated hydroxystilbene. The anti-melanin agents are provided, in several embodiments, in a range of about 0.001% to about 10% (e.g., 0.001%, 0.01%, 0.03%, 0.05%, 0.1%, 0.5%, 1%, 5%, 10%, and ranges in between) % m/m, % m/v, or % v/v in the formulation. In many embodiments, the percentages provided are % m/m or % w/w. In some embodiments, the panthenol compound (e.g., panthenyl triacetate) acts as an anti-irritant and anti-inflammatory. As discussed herein, reducing inflammation may reduce hyperpigmentation through an inflammatory-mediated pathway.
In several embodiments, at least two types of anti-melanin agents are included in a formulation. For example, one type reduces the production of melanin, while the other type(s) degrades (or enhance the degradation of) melanin, reduces the melanin transfer from melanocytes to keratinocytes, and/or reduces the storage of melanin. The use of at least two different anti-melanin agents provides synergistic effects in several embodiments. For example, in one embodiment, the formulation contains a Bidens pilosa extract as an anti-melanin agent to beneficially affect melanin transport as well as a Rheum rhaponticum extract (e.g., acetyl Rheum rhaponticum root extract) as a tyrosinase inhibitor. These two extracts are combined with one or more anti-inflammatories and sun protection agents in many embodiments of the formulation to accomplish a multi-modal approach to effectively address the appearance of skin discoloration (e.g., hyperpigmentation, hypopigmentation, etc.). By affecting different points in the cascade of event that leads to discoloration, several embodiments of the formulation as described herein are particularly advantageous.
In some embodiments of the invention, the anti-inflammatory agents decrease redness and irritation (such as that caused by UV exposure) and fortify resistance to inflammation. The anti-inflammatory agents may have antioxidant properties by reacting with reactive oxygen species. The anti-inflammatory agents may also absorb the energy from UV light and are photo-protective, and reduce UV-induced free radical damage to skin. In several embodiments, the anti-inflammatory agents, by acting through a different pathway that involves inflammation's influence on pigmentation are particularly potent when combined with the anti-melanin agents. Post-inflammatory hyperpigmentation or hypermelanosis, which can occur after cutaneous inflammation or injury, is one example of hyperpigmentation that is related to inflammation, and according to several embodiments, is treated with the formulations described herein. Anti-inflammatory agents used in the formulations described herein include but are not limited to one or more of the following: vitamin E compounds (such as disodium lauriminodipropionate tocopheryl phosphate and other tocopherols), vitamin A compounds, vitamin B compounds, and vitamin D compounds. In several embodiments, the anti-inflammatory agent comprises a vitamin E compound (e.g., disodium lauriminodipropionate tocopheryl phosphate). The anti-inflammatory agents are provided, in several embodiments, in a range of about 0.1% to about 20% (e.g., 0.1%, 0.5%, 0.8%, 1%, 5%, 10%, 20%, and ranges in between) % m/m, % m/v, or % v/v in the formulation. In many embodiments, the percentages provided are % m/m or % w/w.
In some embodiments of the invention, the sun protection agents used have an SPF of 30, 50 or higher. In many embodiments, the sun protection agents are physical sunscreens (and not chemical sun screens) that block both UVA and UVB rays. The sun protection agents used in the formulations described herein include but are not limited to zinc oxide, titanium dioxide and other mineral oxides. The sun protection agents are provided, in several embodiments, in a range of about 2% to about 40% (e.g., 2%, 5%, 10%, 15%, 20%, 25%, 30%, 40%, and ranges in between) % m/m, % m/v, or % v/v in the formulation. In many embodiments, the percentages provided are % m/m or % w/w. In some embodiments, the formulations comprise 5-15% zinc oxide and 10-15% titanium dioxide. The terms sun protection agents, suncreens and sunblocks can be used interchangeably herein. Although physical suncreens are used in many embodiments, chemical suncreens may also be used.

In several embodiments, the invention comprises a method of treating skin using any one of the formulations described above or below. The use of any of the formulations described herein for treating skin (e.g., reducing hyperpigmentation) and/or improving skin appearance is provided in several embodiments. Several embodiments also include instructing the method or use of the formulation (e.g., via instructions for use).
As described above, several embodiments of the present invention relate to unique skin care formulations for treating and protecting skin. The formulations described herein can be beneficial for both healthy and damaged skin. In several embodiments, use of the formulations described herein provides one or more of the following advantages: (i) reduction in the appearance of redness, (ii) reduction in hyperpigmentation (e.g., reduction in age spots, discolored scar tissue, birthmarks, or other discoloration), (iii) skin looks and feels smoother; (iv) increased firmness, (v) increased hydration, (vi) improved skin tone and texture (e.g., increased evenness), (vii) clearer complexion, (viii) improved radiance, (ix) fine lines, pores, and wrinkles appear less visible, (x) improved overall appearance of skin, (xi) reinforcement of the skin's natural defenses, and (xii) improved epidermal structural integrity. Advantageously, in several embodiments, these improvements are obtained with formulations that are gentle and non-irritating, with no or little erythema, edema, dryness, peeling, itching, stinging, tingling, or burning sensation. Because undesired effects are nominal or nonexistent, the formulation fosters regular use by a subject, which enables longer term improvements in skin characteristics.
The formulations described herein can provide both short-term and long-term benefits according to several embodiments. Beneficial effects from use of the formulations described herein occur upon use, within hours of use, within 1-2 days, 3-4 days, about 7 days, about 14 days, or within about 3 weeks. In several embodiments, the skin characteristics continue to improve over about 2-4 weeks, about 4-6 weeks, about 6-10 weeks, or about 12-16 weeks of use.
Several embodiments of the invention comprise a formulation for protecting against UV damage and reinforcing the skin's natural defenses. In some embodiments, the formulation is in a liquid, gel or powder form. The formulations described herein can be applied prior to or after foundation or other make-up. In some embodiments, the formulation is colorless; however, in other embodiments, the formulation contains sufficient color to serve as foundation or cover-up. In some embodiments, the pH of the formulations is slightly basic, slightly acidic or neutral. In some embodiments, a pH of 3-5, 4-6, 5-7, 6-8, or ranges in between, are provided. Lower or higher pH values may also be used.
The formulations described herein have one or more of the following uses: primer, moisturizer, sunscreen, setting mist, and color (cover-up, coverage, or foundation). The unique aspects of many of the formulations described herein provide a multi-functional product that blends skin care and sun care, and offers a high SPF primer, color coverage, skin nourishment, anti-oxidants and a lightening effect (e.g., through a reduction of discoloration or pigmentation).
According to several embodiments, the formulations described herein can be applied by hand, by sponge, by spraying, by applicator, by brush, or through use of a composition-impregnated wipe or tissue. In some embodiments, the formulations are absorbent (e.g., readily absorbable) such that no separate means are needed to enhance absorption. However, in some embodiments, low frequency ultrasound, massage, application of an electrical field, mechanical manipulation or vibration may be used to facilitate absorption. In some embodiments, the formulation is useful post-surgery or dermatological treatment, where, for example, discoloration, may be an issue. Several topical formulations herein described can penetrate top layers of the skin. Further, some of the formulations described herein may be suitable for use for application under one or more skin layers (e.g., as an injectable).
The invention, according to several embodiments, comprises a topical formulation (such as an SPF liquid primer) for treating skin that includes Rheum rhaponticum and asteraceae. In one embodiment, the Rheum rhaponticum comprises acetyl Rheum rhaponticum extract, extracted from the leaf, root, flower or other part of the plant. In one embodiment, the asteraceae comprises Bidens pilosa extract from the leaf, root, flower or other part of the plant. Rheum rhaponticum and Bidens pilosa are unrelated compounds that Applicant believes have unexpected synergistic effects in combination to reduce hyperpigmentation or otherwise treat skin. In addition to extracts of Rheum rhaponticum and Bidens pilosa, both vitamin E compounds and sunscreen are included in some embodiments. Vitamin E compounds, again unrelated to Rheum rhaponticum and Bidens pilosa, are believed to contribute synergistically with Rheum rhaponticum and Bidens pilosa for the treatment of skin, including the reduction of hyperpigmentation. For example, the synergistic combination of Rheum rhaponticum, Bidens pilosa and an anti-inflammatory agent (such as a Vitamin E compound) in some embodiments, decreases melanin synthesis, decreases accumulation of melanin in keratinocytes, and reduces inflammation and redness. Further, in some embodiments, the combination of an anti-melanin agent, such as a tyrosinase inhibitor, and Vitamin E compounds or other anti-inflammatory agents synergistically decreases melanin synthesis, decreases accumulation of melanin in keratinocytes, and reduces inflammation and redness. In some embodiments, the Rheum rhaponticum and the Bidens pilosa are provided in the range of about 0.0005-10% and the vitamin E is provided in the range of about 0.05-10%. Sunscreen may be provided in the range of about 1-35%. Sunscreen provides an additional benefit by shielding the regions of hyperpigmentation from further pigmentation during the treatment process, thus facilitating the therapeutic benefits of the formulation. Further, sunscreen reduces the incidence of future hyperpigmentation and damage. In some embodiments, Thermus thermophillus (e.g., Thermus thermophillus ferment) is included with extracts of Rheum rhaponticum and Bidens pilosa and optionally Vitamin E compounds, sunscreen, and other ingredients. The Thermus thermophillus, which is unrelated to Rheum rhaponticum, Bidens pilosa and vitamin E, is believed to provide further synergistic benefits to the combination of Rheum rhaponticum and Bidens pilosa (and optionally Vitamin E compounds). For example, Thermus thermophillus, in some embodiments, acts as an antioxidant that is activated by heat and/or light thereby protecting against UV damage, which in turns preserves and reinforces the skin's natural defenses and improves epidermal structural integrity. Thermus thermophillus may also work as an anti-oxidant to supplement the vitamin E compound's ability to reduce inflammation, thereby reducing the effect of inflammation on increased pigmentation (e.g., through inflammatory mediators). To Applicant's knowledge, several combinations of ingredients disclosed herein represent unique formulations that are not naturally occurring (e.g., not found in nature in such combination). Moreover, in several embodiments, the individual ingredients are modified so as to be structurally and/or functionally different than the naturally-occurring species, thereby resulting in markedly unique effects.
In addition, in some embodiments, at least one of the following ingredients is included: a skin conditioning agent, a solvent, a silicone, an emollient, a preservative, a thickener, an antioxidant, an anti-inflammatory agent, and an excipient. Colorants and fragrances may additionally be included. In some embodiments, the formulation further includes one or more of the following: amino acids, peptides, phospholipids, additional vitamins, growth factors, and additional anti-aging compounds. Surfactants, gelling agents, and pH balancers may also be included.
In several embodiments, the formulation comprises a combination of various combination groups and individual ingredients. In some embodiments, the formulation comprises, consists essentially of or consists of several or all of the following groups of ingredients (or in certain cases of water and sandalwood, single ingredients):

Tocopherol is a vitamin E compound, with benefits described herein.
Bidens pilosa extract combined with acetyl Rheum rhaponticum root extract work synergistically in several embodiments to enhance the anti-melanin effects. In some embodiments, the ratio of Bidens pilosa and a Rheum rhaponticum extract is 1:1, 1:2, 1:3, 1:4, 1:5, 1:10, 1:25, and ranges in between. In some embodiments, the ratio of the Rheum rhaponticum extract and Bidens pilosa is 1:1, 1:2, 1:3, 1:4, 1:5, 1:10, 1:25, and ranges in between. The two agents when combined work synergistically as anti-melanin agents, and further when combined with vitamin E compounds, provide enhanced synergy with the anti-inflammatory effects. Additionally, when combined with a high SPF (such as SPF 30, 50 or more), the formulations' effects on lightening skin are further pronounced. In some embodiments, the ratio of vitamin E compounds (or other anti-inflammatory agents) to the anti-melanin agent(s) is 1:1, 2:1, 3:1, 4:1, 5:1, 10:1, 25:1, and ranges in between.
As described herein, anti-inflammatory agents other than vitamin E compounds can be used in addition to, or in lieu of, vitamin E compounds. Anti-inflammatory agents are used, in some embodiments, to inhibit the inflammatory pathway that can affect melanin. For example, during the inflammatory process in the epidermal layer, inflammatory mediators (such as cytokines, chemokines, prostanoids such as prostaglandins, reactive oxygen species, etc.) may be released. The inflammatory mediators, in turn, may stimulate melanocytes to affect the production, sequestering, and/or processing of melanin in a manner that contributes to hyperpigmentation. An anti-inflammatory agent, as used herein in several embodiments, interrupts (e.g., or otherwise inhibits) this pathway, which in turn helps to reduce hyperpigmentation. In some embodiments, the balancing of inflammation and inflammatory pathways is accomplished.

The topical formulations described herein may be used as a primer. In addition, according to several embodiments, the formulations may be foundation, blush, lip color, eye color, lotions, creams, serums, gels, cleansing formulations, eye creams, sunscreens, bronzers, powders, nail care, hair care, and other cosmetics and skin care products.
According to several embodiments, the ingredients may be delivered in a single formulation or separately. For example, the anti-melanin agent and the anti-inflammatory agent and sunscreen can be in a single formulation. Alternatively, the ingredients or groups of ingredients may be provided in separate compositions. For example, the anti-melanin agent(s) and the anti-inflammatory agent(s) may be in one formulation and the sunscreen in another. The topical formulations are, according to several embodiments, applied once a day, twice a day, or every other day. Greater frequencies may also be used. Lesser frequencies may also be used, for example in maintenance phase after the desired effects have been achieved. Multi-chamber dispensers can be used in some embodiments. In several embodiments, a kit comprising a formulation and one or more skin care or cosmetic products is provided. In one embodiment, the kit comprises the anti-melanin and anti-inflammatory agents in one unit and the sunscreen separately. In one embodiment, the kit comprises the anti-melanin and anti-inflammatory agents in one formulation and, optionally, a separate keratolytic. Applicators (brushes, sticks, sponges, etc.) may be provided to apply the formulations described herein, and may also be included in a kit. The kit can comprise one or more of the formulations described herein in varying strengths (e.g., of the active ingredients). The kit can comprise one or more of the formulations described herein as well as an addition sunscreen and/or exfoliant. In some embodiments, the formulations described herein can be applied by transdermal patch.
In several embodiments, hyperpigmentation is reduced by 10-100% after use. For example, significant lightening effects and improvements in pore size, fine lines, overall appearance, radiance, skin smoothness, and/or skin tone (evenness) are visible in several embodiments after 4 weeks, 8 weeks and 12 weeks. Certain improvements in skin may be visible or felt upon use or within days of use. Although specific regions of hyperpigmentation are treated according to several embodiments, an overall lightening or brightening effect can also be achieved on skin that has no identifiable regions of hyperpigmentation.
Several embodiments of the formulations are particularly advantageous because they provide coverage (e.g., color, camouflage) in a formulation that goes on smoothly and is not chalky or sticky. This is helpful to cover areas of hyperpigmentation while the formulation is simultaneously working to reduce said hyperpigmentation. This is also helpful to minimize the number of products a user applies to his/her face (or body) because it reduces the need for a separate foundation.
Several embodiments of the formulations are water resistant. In one embodiment, the formulation is water resistant, e.g., with respect to SPF, for up to 30, 40, 60 and 120 minutes. Long-wear formulations are provided in several embodiments.
The formulations, according to several embodiments, are especially effective because they offer a multi-modal approach to reduction of hyperpigmentation. The combination of the anti-melanin agent with the anti-inflammatory and sunscreen provides a multi-modal approach that addresses discoloration via multiple pathways and results in the creation of a unique and effective formulation. In several embodiments, the anti-inflammatory agents, by acting through a pathway that involves inflammation's role in hyperpigmentation, are particularly effective when combined with the anti-melanin agents.
In some embodiments, one or more keratolytic agents may be optionally included. For example, one embodiment comprises or consists essentially of one or more keratolytic agents, one or more anti-melanin agents (such as tyrosine inhibitors), one or more anti-inflammatory agents, and one or more sun protection agents. The keratolytic agent(s), anti-melanin agent(s) (such as tyrosine inhibitors), and anti-inflammatory agent(s) (such as vitamin E compounds) work synergistically together in many embodiments to counter undesired pigmentation. The keratolytic agents used herein can, in one embodiment, break down the keratinized outer layer of the epidermis. Keratolytic agents may help remove or soften older, damaged surface tissue (e.g., keratin) and promote the generation of new skin cells. In several embodiments, keratolytic agents are retinoid-like compounds (such as from a vegetable or botanical source), improve skin radiance and texture, produce a lightening effect, reduce melanin, and or restore firmness. Keratolytic agents used in the formulations described herein include but are not limited to one or more of the following: extracts from the aster family of plants (such as asteraceae, Bidens pilosa), salicylic acid, alpha hydroxy acid, beta hydroxy acid, sulfur, azelaic acid, glycolic acid, urea, lactic acid, resorcinol, allantoin, and fruit acids. In some embodiments, the keratolytic agent includes Bidens pilosa extract, and one or all of palm oil, cottonseed oil, linseed oil and tocopherol. In some embodiments, exfoliants are used in addition to or in lieu of keratolytic agents. Exfoliants can be chemical or mechanical. The keratolytic agents are provided, in several embodiments, in a range of about 0.005% to about 10% (e.g., 0.005%, 0.05%, 0.1%, 0.5%, 1%, 5%, 10%, and ranges in between) % m/m, % m/v, or % v/v in the formulation. In some embodiments, the ratio of the keratolytic and the anti-melanin agent is 1:1, 1:2, 1:3, 1:4, 1:5, 1:10, 1:25, and ranges in between. In some embodiments, the ratio of the anti-melanin agent and the keratolytic is 1:1, 1:2, 1:3, 1:4, 1:5, 1:10, 1:25, and ranges in between. Although Bidens pilosa may have keratolytic properties in some aspects, several embodiments include Bidens pilosa for its anti-melanin properties rather than its keratolytic properties.
Despite the large number of skin care formulations on the market, there remains a need for a formulation that simultaneously reduces skin redness and skin irritation in a multi-modal manner, offers significant UV protection (such as physical UVA and UVB sun protection), and provides color correction, all in a non-irritating formulation that goes on smoothly. Because redness can correlate with inflammation and sensitivity, there is a particular need for a formulation that is both efficacious and suitable for sensitive skin, and additionally incorporates a broad-spectrum sunscreen, without being irritating or chalky.
Several embodiments of the present invention meet the needs recited above. In several embodiments, the invention comprises a unique topical formulation with an SPF of at least 30 (e.g., 50) for neutralizing redness and soothing sensitive skin comprising niacinamide, bisabolol, tocopheryl phosphates (a vitamin E compound), Crithmum maritimum extract, Magnolia officinalis bark extract, and Zingiber officinale (ginger) root extract, magnesium carboxymethyl beta-glucan, and jojoba esters, as well as other ingredients.
In many embodiments, the reduction of inflammation through the inclusion of an anti-inflammatory agent synergistically works with the other ingredients to counter skin redness/irritation via multiple pathways to inflammation, promote skin repair and improve overall skin health. The inflammation and irritation that is ameliorated by several embodiments herein may have been caused by, for example, an immune response (e.g. allergy), genetics, the aging process, or environmental causes (such as UV exposure).
Several embodiments disclosed herein provide for comprehensive skin care formulations that target one or more inflammatory mediators, thereby serving as anti-redness and anti-irritants and providing soothing, healing, or otherwise soothing effects for sensitive, reddened, or otherwise irritated skin.

In several embodiments, the formulations provided for herein function to alleviate one or more pathways that can contribute to skin redness and/or irritation. For example, mechanical factors may cause skin redness and/or irritation in some embodiments. Additionally, physical and/or chemical factors may also play a role in development of skin redness and/or irritation, either alone or in combination with mechanical factors. Non-limiting examples of mechanical factors that can cause, contribute to or are associated with skin redness and/or irritation include mechanical hair removal, such as shaving or waxing, scrapes, abrasions (e.g., first, second or third degree), heat or drying effects from external sources, such as a hair dryer, or other mechanical means that create friction against the skin and can damage or injure one or more skin layers. In some embodiments, physical factors work in conjunction with mechanical factors to lead to skin redness and/or irritation. Physical factors include, but are not limited to, UV exposure (e.g., sunlight), varied temperatures—whether hot or cold, either of which can cause an imbalance in skin health, other environmental factors such as humidity, and the like. For example, a cold environment can cause drying of skin, in part because of lower humidity, with the drying of the skin leading to cracking or other skin damage/loss of hydration, which can lead to skin irritation or redness. Similarly, elevated temperatures or high humidity can cause excessive perspiration or greater than normal moisture on skin surfaces, which can then lead to development of frication and/or skin abrasions, which as discussed above can lead to skin damage. Chemical factors, which may work in combination with physical and/or mechanical factors, can cause also skin irritation or redness. Chemical factors include, but are not limited to, certain sunscreens or other topical compositions (e.g., lotions, facial masks etc.), chemical hair removal agents, retinol (e.g., retinoid skin creams), exposure to preservatives (e.g., those in certain topical formulations).
In several embodiments, mechanical, physical, or chemical factors (or combinations of any or all of such factors) that can affect skin negatively are treated by the formulations described herein; for example one or more of these factors can initiate or otherwise promote skin redness, irritation or damage through damage or injury to the outer layers of skin, which normally function as a protective barrier. In some embodiments, these factors can cause a loss of natural or endogenous moisturizing factors, which can lead to dryness, loss of skin hydration and susceptibility to other pro-damaging factors or environments. Loss of lipids (e.g., epidermal lipids in the stratum corneum) can further degrade the barrier function of the skin, rendering it more susceptible to other factors and possibly to infectious agents. Pro-damaging factors can also lead to loss of, degradation of, or reduced production of certain skin proteins. Various proteins serve to maintain the working structure of skin cells, maintain a tight and intact external skin layer, and generally promote and maintain the barrier function of skin.
At least one result of the damages to the skin or reduction in barrier function is the subsequent cascade of biochemical events that occur in deeper layers of the skin, such as the epidermis. In the epidermal layer, a series of proinflammatory reactions can occur as a result of mechanical, chemical and/or physical events. For example, various proinflammatory cytokines can be released (II-1alpha, leukotriene B4, tumor necrosis factor alpha, prostaglandin E2, etc.). In several embodiments, there are multiple cascades or layers of proinflammatory cytokines. In some embodiments, one or more of the proinflammatory cytokines are released from, for example, keratinocytes and/or mast cells. These proinflammatory cytokines can have wide ranging effects, from local infiltration of immune cells, to activator of downstream receptors, such as heat receptors (which later impact neural sensory pathways to further exacerbate skin irritation. Further, mast cells can also release mediators of itching sensations (e.g., histamine). These various proinflammatory cytokines can activate cognate receptors and induce a change in neural signals that lead to an increased sensation of itching, burning, skin tightness, heat, etc. Not only does the activation of these pathways lead to the increased sensations of irritation, the increased sensations can lead to an individual exacerbating the problems (e.g., by itching the skin, further damaging the surface and generating more inflammatory mediator release), as well as additional reddening of the skin.
Furthermore, there can result, in several embodiments, more long term changes to the cells making up the various skin layers. For example, there can be alterations in proliferation and/or differentiation of cells in the skin. In one embodiment, keratinocytes, which serve as barrier cells, can overproliferate which can lead to a coordinate excess of proinflammatory cytokine production and/or skin thickening. Likewise, changes in keratinocyte differentiation can be altered, thereby altering the balance between the various types of cells in the skin. These longer-term changes can result in a feed forward effect that leads to further skin susceptibility to the various factors that led to initial injury (e.g., mechanical, physical, chemical). As a result, the skin's natural barrier function can continue to degrade, which leads to dry, damaged, and sensitive skin—such characteristics being associated with increased chances for additional skin damage and irritation. Thus, mechanical, physical and/or chemical factors can create a cycle or loop of skin irritation and redness.
In several embodiments, the formulations described herein address (e.g., limit the effects of) one or more of these causes and/or symptoms of damaged, irritated, or reddened skin. In several embodiments, the formulations described herein reduce the impact of mechanical factors on the skin and its barrier function. In several embodiments, the formulations provided for herein reduce the impact of chemical factors on the skin and its barrier function. In several embodiments, the formulations described herein reduce the impact of physical factors on the skin and its barrier function. In several embodiments, the formulations described herein limit release and/or effect of proinflammatory cytokines and/or other inflammatory mediators. In several embodiments, the formulations provided for herein limit the longer-term changes that could negatively impact skin, thereby limiting or reducing the feed-forward effect discussed above. In one embodiment, the formulations described herein maintain or enhances lipid production in the skin, for example, by stimulation of synthesis of certain ceramides, which are major components of the stratum corneum. In several embodiments, production of ceramides such ceramide Ill or VI, and/or enzymes that play a role in ceramide formation (e.g., beta-glucocerebrosidase) is elevated through use of the formulations described herein, which can enhance barrier function (and also moisture retention). In several embodiments, production or maintenance of other structural components of the skin, such as filaggrin (monomers that are incorporated into skin lipids, thereby enhancing skin barrier function) is increased through use of the formulations described herein, which enhances the ability of the skin to resist negative impacts of mechanical, physical and/or chemical factors (and thus become less susceptible to irritants).
In still additional embodiments, the formulations described herein enhance one or more of skin cell regulation and overall skin protection. Cellular regulation of skin cells can be positively impacted by the formulations provided for, for example, by promoting proliferation of certain cells, such as epidermal basal cells. Also enhanced in several embodiments is cellular respiration. In conjunction, these effects result in a larger overall population of healthy skin cells, with each cell, or the majority of cells, undergoing greater regulation of cellular respiration to avoid or eliminate, for example, free radical production or other factors (e.g., production of proinflammatory cytokines) that could compromise skin function or integrity. Skin protective effects are also achieved through the use of formulations disclosed herein. For example, in several embodiments, the formulations regulate (e.g., reduce) proinflammatory mediators. Additionally, cellular stressors (e.g., free radicals resulting from oxidative/metabolic stress) are regulated (e.g., reduced to a normal, healthy level). In several embodiments, the formulations also provide an increased barrier function that allows the cells of the skin to become properly hydrated (thereby increasing the water reservoir of the skin) and also preventing or reducing loss of water through the skin, especially damaged skin.
In several embodiments, the topical formulation is a liquid, cream, serum, or gel. Depending on the embodiment, at least one of the Zingiber officinale, bisabolol (natural or synthetic) or an asteraceae extract, Crithmum maritimum, and Magnolia officinalis extracts are root extracts. In several embodiments, the topical formulation decreases production of inflammatory mediators, improves the barrier function of the skin, leading to improved hydration and antioxidant production, and/or conditions the skin while providing protection from UV exposure.
The use of agents, ingredients and compounds may be used interchangeably herein. In several embodiments, reference to the term “based” includes the recited agent, ingredient or compounds.

The invention, according to several embodiments, comprises a topical formulation (such as a liquid formulation with anti-irritant effects) for treating skin that includes extracts of ginger and bisabolol (natural or synthetic) or an asteraceae extract. In one embodiment, the ginger comprises Zingiber officinale extracted from the leaf, root, flower or other part of the plant. In several embodiments, the bisabolol (natural or synthetic) or asteraceae extract comprises a sesquiterpene alcohol, such as a monocyclic sesquiterpene alcohol. In several embodiments, bisabolol (also known as levomenol) is used in a synthetic format. In several embodiments, the asteraceae extract is derived from the chamomile leaf, root, flower or other part of the plant. In one embodiment, the bisabolol is provided as an essential oil. In one embodiment, the bisabolol is optionally synthetic. In some such embodiments, synthetic bisabolol may comprise a racemic mixture of α-(−)-bisabolol and α-(+)-bisabolol. Zingiber officinale and bisabolol (natural or synthetic) are unrelated compounds that Applicant believes have unexpected synergistic effects in combination to reduce skin irritation, reduce skin redness, or otherwise treat skin. In several embodiments, these compounds synergistically act to reduce one or more inflammatory mediators, such as interleukins and prostaglandins. In one embodiment, these compounds reduce production of, inhibit the activity or, or otherwise diminish the effects of one or more of interleukin 1 alpha, tumor necrosis factor (e.g., TNF alpha), cyclooxygenase (e.g., COX-2) or prostaglandin E2.
In several embodiments, topical formulations provided for herein additionally comprise an extract from the Magnolia plant. In some embodiments, the Magnolia extract comprises an extract that is extracted from the leaf, root, flower or other part of the plant. In one embodiment, the Magnolia extract is extracted from the bark of the plant. In several embodiments, the extract comprises one or more anti-inflammatory substances. For example, the extract comprises, in some embodiments magnolol and/or honokiol. These substances act synergistically to inhibit activation of inflammatory mediators and mediators of skin aging. For example, in several embodiments, the activity of NF-KB is inhibited. Moreover, in several embodiments, the Magnolia extract acts to protect skin against chronic inflammation, neutralize internal aging factors and to reduce skin redness. In some embodiments, the Magnolia extract is coupled with one or more triglycerides, such as those derived from coconut oil. In one embodiment, the triglycerides comprise caprylic and capric fatty acids of coconut oil, rather than a complete spectrum of all the fatty acids of coconut oil. In several embodiments, the caprylic and capric fatty acids act synergistically with the Magnolia extract (or with other ingredients of the composition) to provide anti-inflammatory, anti-irritating, anti-redness effects and/or any of the other positive skin effects disclosed herein.
In several embodiments, the formulations provided herein further comprise one or more Crithmum plant extracts. In several embodiments, the extract is extracted from the leaf, root, flower or other part of the plant.

The thickener can optionally include methylcellulose in alternate embodiments. The percentages are provided as % m/m in some embodiments. In other embodiments, these ingredients are provided as % w/w, % m/v, % v/v, % m/w, or % w/v.
In several embodiments, the formulation can have an SPF between 5 SPF and 100 SPF. In some embodiments, the topical composition can have an SPF of 15, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90, 100, and ranges in between. Greater SPF values may also be used in some embodiments. A physical sunscreen with an SPF of 50 is provided in several embodiments.
In several embodiments, the formulation comprises a stabilizer, suspending agent and/or thickener. Dimethicone crosspolymer is a silicon derivative that can be used herein as a stabilizing or a suspending agent or a thickener. Types of dimethicone crosspolymers that can be used as a stabilizing agent, suspending agent or a thickener include, but are not limited to, silicone CS-1600, which is a mixture between dimethicone crosspolymer and cyclopentasiloxane, dimethicone crosspolymer 3, dimethicone crosspolymer PEG-8, cetyl dimethicone/dimethicone cross polymer, and dimethicone/vinyl dimethicone crosspolymer, and combinations thereof.
In several embodiments, a dispersing agent is used in order to achieve a more even distribution (and stabilization, in several embodiments) of solid particles, like pigments and fillers, throughout the formulation. In several embodiments, disteardimonium hectorite, a derivative of the naturally occurring clay mineral hectorite is used, either alone or in conjunction with other agents. Disteardimonium hectorite is generated by replacement of a portion of the sodium cations of hectorite clay with stearyldimonium groups, which include 18 carbon chains. Disteardimonium hectorite is a quaternary ammonium compound, and other compounds of this class can be used, in several embodiments, in addition to or in place of disteardimonium hectorite. In some embodiments, the quaternary ammonium compounds are synthetic, though naturally occurring compounds may also be used. For example, other quaternary ammonium compounds that can be used include, benzalkonium chloride, benzethonium chloride, methylbenzethonium chloride, cetalkonium chloride, cetylpyridinium chloride, cetrimonium, cetrimide, dofanium chloride, tetraethylammonium bromide, didecyldimethylammonium chloride, and domiphen bromide, or combinations of two or more thereof.
In several embodiments described herein, the topical formulation comprises Zingiber officinale extract to beneficially affect skin condition (e.g., smoothness, reduced irritation, increased barrier function, etc.). Zingiber officinale extract can be combined with various oils, other extracts, and/or vitamin compositions, in several embodiments. For example, Glycyrrhiza glabra (licorice) extract, mulberry extract, Sanguisorba officinalis (Great Burnet) extract, Rhodiola rosea extract, Angelica arcangelica extract, and the like may be used, alone or in combination with Zingiber officinale extract (or with other components described herein). Tocopherol is a vitamin E compound, with benefits described herein.
Zingiber officinale extract combined with bisabolol (synthetic or natural) works synergistically in several embodiments to enhance the skin calming, anti-redness and anti-irritant effects. In some embodiments, the ratio of Zingiber officinale and bisabolol is 100:1, 99:1; 90:1; 75:1, 50:1, 25:1, 10:1 and ranges in between. In some embodiments, the ratio of the bisabolol and Zingiber officinale is 100:1, 99:1; 90:1; 75:1, 50:1, 25:1, 10:1, and ranges in between. In one embodiment, the two agents when combined work synergistically as anti-irritant agents, and further when combined with vitamin E compounds and/or niacinimide (e.g., 1-5%) provide enhanced synergy with anti-irritant (e.g., anti-inflammatory) effects. Additionally, when combined with a high SPF (such as SPF 30, 50 or more), the formulations' anti-irritant and anti-redness effects on skin are further pronounced as the SPF formulation reduces further damage/irritation to the skin.
In several embodiments, the Zingiber officinale and/or bisabolol (synthetic or natural) is combined with Magnolia officinalis extract, which functions as a skin conditioning agent, and has antimicrobial properties. In several embodiments, the ratio of Magnolia officinalis extract to Zingiber officinale and/or bisabolol is 50:1, 40:1, 30:1, 25:1:20:1, 10:1, 5:1, 2:1 and ranges in between. In several embodiments, the Zingeber officinale, bisabolol, and/or Magnolia officinalis is combined with Chrithmum maritimum extract, which functions as a skin conditioning agent. In several embodiments, the ratio of Magnolia officinalis extract to Zingiber officinale, bisabolol, and/or Magnolia officinalis is 1:10, 1:25, 1:50, 1:75, 1:100, 1:250, 1:500, 500:1, 250:1, 100:1, 75:1, 50:1, 25:1, 10:1 and ranges in between. In several embodiments, these combinations exhibit synergistic anti-irritant and/or anti-redness effects. In several embodiments, these combinations promote smoother, more hydrated skin that, in turn, reduces future irritation and redness.
As described herein, anti-inflammatory agents other than vitamin E compounds can be used in addition to, or in lieu of, vitamin E compounds. Anti-inflammatory agents are used, in some embodiments, to inhibit the inflammatory pathway. For example, during the inflammatory process in the epidermal layer, inflammatory mediators (such as cytokines, chemokines, prostanoids such as prostaglandins, reactive oxygen species, etc.) may be released. In several embodiments, the vitamin E compounds are used to assist in reduction of effects caused by UV exposure, such as UVA or UVA exposure. In several embodiments, the vitamin E compounds help prevent the formation of sunburn on cells (e.g., epidermal cells). Also associated with this effect, in one embodiment, is the protection or reduction in the UV induced depletion or alteration of epidermal Langerhans cells, the depletion of which is associated with immunosuppression (which can exacerbate heightened skin sensitivity). In several embodiments, the vitamin E compounds also aid in reducing redness or other skin discoloration. An anti-inflammatory agent, as used herein in several embodiments, interrupts (e.g., or otherwise inhibits) this pathway, which in turn helps to reduce inflammation. In some embodiments, the balancing of inflammation and inflammatory pathways is accomplished. In one embodiment, melanin production may also be beneficially affected.

In several embodiments, the invention comprises or consists essentially of cyclopentasiloxane, dimethicone crosspolymer, dimethicone/vinyl dimethicone crosspolymer, dimethiconol, caprylic/capric triglyceride, alumina, silica, polyhydroxysteric acid, jojoba esters, glyceryl behenate/eicosadioate, water, phenoxyethanol, benzoic acid, dehydroacetic acid, glycolic acid, choloracetic acid, ethylhexylglycerin, tocopherol, disteardimonium hectorite, triethoxycaprylylsilane, iron oxides (e.g., CI 77491, CI 77492), chromium oxide greens (e.g., CI 77288) and two or more of bisabolol, Zingiber officinale, Magnolia officinalis bark extract, Crithmum maritimum extract, disodium lauriminodiapropionate tocopheryl phosphates, titanium dioxide, zinc oxide, niacinamide, and magnesium carboxymethyl beta-glucan.
The topical formulations described herein may be used as a primer, foundation, concealer or general skin care product. Facial lotion and eye creams are provided in some embodiments.
According to several embodiments, the ingredients may be delivered in a single formulation or separately. For example, a skin care/conditioning agent and an anti-inflammatory agent and sunscreen can be in a single formulation. Alternatively, the ingredients or groups of ingredients may be provided in separate compositions. For example, the anti-inflammatory agent(s) may be in one formulation and the sunscreen in another. The topical formulations are, according to several embodiments, applied once a day, twice a day, or every other day. Greater frequencies may also be used. Lesser frequencies may also be used, for example in maintenance phase after the desired effects have been achieved. Multi-chamber dispensers can be used in some embodiments. In several embodiments, a kit comprising a formulation as described herein is provided along with instructions for use. In one embodiment, the kit further comprises a separate sunscreen to be reapplied on a more frequent basis (such sunscreen can be provided as a brush on sunscreen). Applicators (brushes, sticks, sponges, etc.) may be provided to apply the formulations described herein, and may also be included in a kit. The kit can comprise one or more of the formulations described herein in varying strengths (e.g., of the therapeutic ingredients).
In several embodiments, skin irritation is reduced by 10-100% after use. For example, significant skin calming effects and improvements in overall appearance, radiance, skin health, skin smoothness, and/or skin tone (evenness, e.g., lack of redness) are visible in several embodiments after 4 weeks, 8 weeks and 12 weeks. Certain improvements in skin may be visible or felt upon use or within days of use. Although specific regions of skin irritation or redness are treated according to several embodiments, an overall skin rejuvenating effect can also be achieved on skin that has no identifiable regions of irritation.
Several embodiments of the formulations are particularly advantageous because they provide coverage (e.g., color, camouflage) in a formulation that goes on smoothly and is not chalky or sticky. This is helpful to cover areas of redness or irritation while the formulation is simultaneously working to reduce said redness or irritation. This is also helpful to minimize the number of products a user applies to his/her face (or body) because it reduces the need for a separate foundation. A beige formulation with green undertones is provided to counteract redness in some embodiments. A non-fragranced clear formulation is provided in other embodiments.
Several embodiments of the formulations are water resistant. In one embodiment, the formulation is water resistant, e.g., with respect to SPF, for up to 30, 40, 60 and 120 minutes. Long-wear formulations are provided in several embodiments.
The formulations, according to several embodiments, are especially effective because they offer a multi-modal approach to reduction of redness or irritation. The combination of the skin conditioning agent with the anti-inflammatory and sunscreen provides a multi-modal approach that addresses discoloration via multiple pathways and results in the creation of a unique and effective formulation. In several embodiments, the anti-inflammatory agents, by acting through a pathway that involves inflammation's role in irritation, are particularly effective when combined with the skin conditioning and/or antimicrobial agents.
In some embodiments, one or more mild keratolytic agents may be optionally included, wherein the keratolytic is gentle enough to be used on sensitive skin that is, for example, irritated, inflamed, and red. Mild keratolytic agents may help remove or soften older, damaged surface tissue (e.g., keratin) and promote the generation of new skin cells. Mild keratolytic agents used in the formulations described herein include but are not limited to one or more of the following: plant extracts (such as from the aster family), salicylic acid, alpha hydroxy acid, beta hydroxy acid, sulfur, azelaic acid, glycolic acid, urea, lactic acid, resorcinol, allantoin, fruit acids, and fruit oils. Gentle exfoliants include chemical or mechanical exfoliants. The keratolytic agents are provided, in several embodiments, in a range of about 0.005% to about 10% (e.g., 0.005%, 0.05%, 0.1%, 0.5%, 1%, 5%, 10%, and ranges in between).

In some cases, where siloxanes are included such as cyclopentasiloxane, a by-product (such as cyclotetrasiloxane in one embodiment) may be present at, for example, 0.1%, 0.5%, 1%, 2%, 5%, and ranges in between.
In those embodiments in which caprylic/capric triglycerides are provided, they may be used, for example, as skin conditioners and/or occlusive agents, the latter serving, in several embodiments, to increase the hydration of the skin (e.g., by preventing loss of moisture through the skin), thereby reducing the tendency of dry skin to become irritated. In some embodiments, caprylic/capric triglycerides are a mixed triester derived from coconut oil and glycerin. Caprylic/capric triglycerides function as a skin conditioning agent in several embodiments, helping to soften, smooth, and/or improve water barrier functions of skin. In several embodiments, they also function as emollient, dispersing agent and/or solvents. In several embodiments, the triglycerides provide a non-greasy barrier as well as skin lubrication. In several embodiments, their use can enhance delivery of ingredients contained in the formulations disclosed herein.

Components may be isolated and/or purified before or after extraction in some embodiments.
Where percentages are provided for agents, ingredients and compounds, they can be % m/m, % m/w, % w/w, % m/v, % v/v and variations thereof with respect to the formulation as a whole, unless otherwise indicated.
The use of agents, ingredients and compounds may be used interchangeably herein. In several embodiments, reference to the term “based” includes the recited agent, ingredient or compounds. For example, a vitamin E-based compound includes vitamin E itself. As used herein, the terms composition and formulation can be used interchangeably. Salt forms of the acids identified herein may be used instead of or in addition to the acid.
With respect to the use of plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application.
It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (for example, bodies of the appended claims) are generally intended as “open” terms (for example, the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (for example, “a” and/or “an” should be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. For example, “an” agent can include one, two or several ingredients (and not necessarily a single ingredient). In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number (for example, the bare recitation of “two recitations,” without other modifiers, means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (for example, “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
In addition, where features or aspects of the disclosure are described in terms of Markush groups, those skilled in the art will recognize that the disclosure is also thereby described in terms of any individual member or subgroup of members of the Markush group.
