1. Field of the Invention
The present invention relates to cosmetic compositions and, in particular, to multi-purpose skin care compositions.
2. Description of the Related Art
Various skin care products such as creams, lotions, bar soaps and gels are commercially available to cleanse, moisturize, exfoliate and minimize wrinkling of the skin. Typically, these skin care products are designed for a singular purpose. In order to achieve multiple benefits, an individual may have to use more than one skin care product. Recently, skin care products have been developed that may have more than one use such as a combination cleanser and moisturizer. However, there can some difficulty in producing multi-use products as the physical properties of each individual component may not be compatible with one another. Also, these multi-purpose products may not be as effective when used alone. Accordingly, there remains a need for multi-purpose skin care products that can provide multiple skin care benefits.

Exemplary embodiments disclosed herein are directed to skin care compositions that include one or more ingredients that provide a plurality of skin care benefits such as, but not limited to, exfoliating the skin naturally, reducing fine lines and wrinkles and improving skin elasticity and firmness.
According to a first embodiment, the skin care composition is composed of a safe and effective amount of at least one anti-wrinkling agent and a safe and effective amount of a natural exfoliating complex.
In another embodiment, the anti-wrinkling agent is a hexapeptide. In another embodiment, the hexapeptide is an acetyl hexapeptide-3.
In yet another embodiment, the natural exfoliating complex is composed of ahnfeltia cocinna. In another exemplary embodiment the natural exfoliating complex also includes butylene glycol and glycosaminoglycans.
In yet another embodiment, the skin care compositions include a safe and effective amount of a hexapeptide or a hexapeptide complex, preferably in combination with one or more of the following ingredients: Willow Bark Extract, APT (glycosaminoglycans, water, butylenes glycol and Ahnfeltia extract), Moist 24 (Imperate Cylindrica (Root) Extract, Water, Glycerin, PEG-8, and Carbomer), Skin Flux, Polyolprepolymer-15, Dipalmitoyl Hydroxyproline (DPHP), Deliner (zea mays extract), and Oat Beta Glucan.
In yet another embodiment, the compositions contain at least three ingredients selected from the following group: a hexapeptide complex, Willow Bark Extract, APT (glycosaminoglycans, water, butylenes glycol and Ahnfeltia extract), Moist 24, Skin Flux, Polyolprepolymer-15, Dipalmitoyl Hydroxyproline (DPHP), Deliner (zea mays extract), and Oat Beta Glucan.
In other embodiments, the skin care composition may include one or more additional components such as, but not limited to, conditioning agents, skin protectants, antioxidants, sunscreen actives, cleansing agents, cosmetic soothing aids, or the like.
The hexapeptide complex is an anti aging ingredient that is chemically combined from naturally derived amino acids that minimizes and softens fine lines. It is an excellent wrinkle reducer of the fine to medium depth “expression” lines, and specifically targets the repeated, biomechanical, muscular contractions of facial expressions such as laughing, squinting, frowning, etc. by functioning to reduce the intensity of these muscle contractions that overtime engrave wrinkles in the skin. It also helps to relax muscles, as opposed to paralyzing them, like botox, thereby reducing the appearance of wrinkles without toxicity and without the loss of natural expression. Thus, it offers an injection free, non-toxic alternative to botox. The hexapeptide complex is preferably an acetyl hexapeptide-3. Depending on the application of the skin care composition, the amount of hexapeptide and other ingredients used may be varied. The skin care composition may include hexapeptide complexes having hexapeptide concentrations ranging from approximately 0.00001 to approximately 15% w/w, preferably from 0.01% w/w to 10% w/w, and more preferably from 0.1 to 5%.
The hexapeptide component of the hexapeptide complex has been clinically shown to minimize wrinkling of the skin. As those skilled in the art will appreciate, wrinkling of the skin can be attributed to natural aging and overexposure to the sun. Although the mechanism of wrinkle formation is not completely known, studies have shown that visible fine wrinkles may be attributable to a reduction in the number and size of elastic fibers in the papillary dermis, an atrophy of the dermis and a reduction in subcutaneous adipose tissue. With respect to coarse wrinkles, studies have shown that these wrinkles may be attributed to excessive deposition of abnormal elastic elements in the upper dermis and thickening of the skin.
The hexapeptide component has been shown to reduce wrinkle formation by reducing the release of catecholamines and limiting the production of SNARE complexes, which are membrane proteins that regulate neurotransmitter release. Studies have shown that minimizing the production of the SNARE complexes decreases the formation of coarse wrinkles. Additionally, the hexapeptide compound has been shown to minimize the overproduction and release of catecholamines, which are attributable to wrinkle formation and fine wrinkles.
APT or APT GC is a natural, mild, exfoliation medium that increases cellular turnover (fibroblast proliferation) by approximately 18% within about 4 weeks, without the over stimulation commonly caused by the use of alpha hydroxyacids or retinal that commonly irritated and cause hyperplasia (an uneven thickening of the skin in an erratic formation). Thus, cells rebuild more slowly and in a more uniform and organized manner like a brick and mortar fashion. This slow rebuilding process ensures a more perfected, symmetrical, cell alignment, and therefore, a more uniform skin health, firmness, elasticity, and tonality or skin opacity. Raw material cell culture studies show that the newly rebuilt cells possess a high water binding capacity that provide intense, immediate, super hydration. Also, the APT can increase the density of the collagen bundles of the upper dermis, which can lead to greater skin elasticity. The Ahnfeltia Concinna component of APT provides for the natural exfoliation of skin. In contrast to prior art exfoliants such as AHA, APT GC can permit the uniform exfoliation of the skin. That is, while AHA can increase skin cell turnover (i.e. exfoliate the top layer(s) of skin), it is particularly harsh and may cause “skin shock” that may cause redness and irritation of the skin. Accordingly, the underlying skin layers may regenerate at different rates leading to uneven skin appearance. Furthermore, AHA can have different rates of penetrating the skin that may also contribute to blotchiness that can be associated with exfoliation procedures.
In contrast to prior art exfoliants, APT can improve skin tone by approximately 15% after 4 weeks of use. The APT component can be more uniformly absorbed by the skin to reduce blotchiness. Also, pore size can be reduced by approximately 35% and skin texture can be improved by approximately 42% after 4 weeks of use. Furthermore, because the APT component does not utilize harsh chemicals, redness and irritation can be reduced. With respect to skin redness, the skin care composition can improve skin redness (i.e., lessen skin redness) by approximately 25% after 2 weeks and by approximately 33% after 4 weeks of use. With respect to skin irritation, the skin care composition can decrease skin irritation by approximately 9% after 2 weeks and approximately 23% after 4 weeks of use. The concentration of APT contained in the formulations preferably ranges from 0 to approximately 5% w/w and more preferably from approximately 0.01% w/w to approximately 2% w/w.
The willow bark extract is a natural exfoliating extract that can increase the cellular renewal capability of the formulations better than salicylic acid and with less irritation. The willow bark extract also creates a general improvement in the skin's appearance that results in smother skin and a reduction in fine lines and wrinkles. The willow bark extract that is used in the compositions of the present invention is preferably white willow bark which has an irritation factor comparable to that of glycerin tat registers at an almost non-existent level. It is therefore a well suited exfoliation vehicle for aging, dry, dehydrated, and sensitive skin. The amount of willow bark extract used in the formulations of the present invention ranges from approximately 0 to 5% w/w, and more preferably from between 0.2 and 2.5%.
The Moist 24 component is a plant based, twenty four hour, long lasting moisturizer that is beneficial for the continuous hydration of aging skin. It is also excellent for dry, dehydrated skin that is deficient in potassium, since potassium balances the acid/alkaline system in the body and works with sodium to regulate the skin's water balance among many other functions. The Moist 24 used in the formulations of the present invention preferably ranges from between approximately 0 and 3% w/w, and more preferably between approximately 1 and 0.25%.
DPHP reduces wrinkles caused by physiological aging. It defends against both natural and photo-induced skin aging factors, including weakening of the collagen fiber network, degrading of the dermal matrix and the dermal/epidermal junction, and free radical damage that has mediated to skin cells within the fibroblasts. It further helps to prevent resulting skin aging effects including flaccid, lose skin, loss of tone and firmness, development of wrinkles and crow's feet, skin structural loss and moisture content. Additionally, it delivers a complex, triple action effect upon aging including anti-wrinkle, effects, long lasting lipophilic moisturizing activity, and skin firming by stimulating pro-collagen production to protect the extra cellular dermal matrix, protecting the elastin in the skin, and protecting fibroblasts against free radicals. The preferred amount of DPHP used in the formulations of the present invention ranges between 0 and approximately 1% w/w.
The Skin Flux component effectively enhances skin moisture because of its unique skin identical lipid concentration. It improves skin barrier function and therefore provides exceptional protection for the skin. It further enhances the delivery and exchange of skin lipids to facilitated “lipid dry” skin conditions as opposed to “water dry” conditions, and is ideal for aging, dry, dehydrated and sensitive skin that in most cases, commonly experiences depleted lipid content. The preferred amount of Skin Flux used in the compositions of the present invention ranges from 0 to approximately 5%, and more preferably from between 1 and 2% w/w.
Polyolprepolymer-15 is a component which improves the deposition of actives in the upper layers of the skin and creates a well suited delivery systems for the active ingredients in the compositions of the present invention. It ensures a slow, but optimum timing of the deposition of the active components due to its chemical structure and molecular weight, creating within the stratum cornium a long lasting liquid reservoir for release of various materials in the skin. The prepolyolprepolymer-15 component is particularly ideal for compositions which have a high amount of active ingredients, since it slows their penetration in a timed release manner that does not shock the skin.
As the skin ages, the prefect integrity of the extra-cellular matrix, which is a combination of collagen, elastin, and glycosaminoglycans, undergoes alterations causing wrinkles to appear. The Deliner component stimulates fibronectin synthesis, which is the webbing of the extra-cellular matrix, which in turn, enables fibroblast to migrate to those areas of the matrix that have been altered or badly damaged. As a result, fibroblastic synthesis is reactivated and reforms the extra-cellular matrix. Ultimately the repaired matrix provides support and firmness to the skin tissue causing wrinkles to fade. The preferred amount of Deliner used in the compositions of the present invention may range from 0 to approximately 2% w/w, and is more preferably around 1%.
Oat Beta Glucan is a natural, soothing plant derivative which has anti-inflammatory properties. This component increases collagen synthesis and cell renewal, reduces fine lines and wrinkles, protects the skin from UV damage, and serves as a protective film-forming agent. The preferred amount of Oat Beta Glucan used in the compositions of the present invention may range from approximately 0 to 5% w/w, and more preferably between 1 and 2%.
The combination of ingredients of the skin care compositions of the present invention are believed to provide synergistic benefits which are otherwise not available with any one of the components used by itself. Clinical evaluations based on the use of the hexapeptide complex itself evidenced a reduction in fine lines and wrinkles, including laugh lines, frown lines, and smile lines, by approximately 13% after 2 weeks and approximately 33% in 4 weeks of use. It was further observed that 100% of participants experienced a reduction in under-eye fine lines and wrinkles on the average of approximately 16% after 4 weeks and approximately 52% after 8 weeks of use. Additionally, an increase in moisture content by 37% after 15 minutes of use was observed.
It is further believed that the compositions of the present invention may improve skin complexion causing the skin to be more flawless and even-toned. Additionally, it is believed that the use of the compositions may increase cellular turnover by 100% with minimal irritation after approximately 2 to 4 weeks of use.
Furthermore, in other exemplary embodiments, the skin care composition may include other components including, but not limited to, conditioning agents, skin protectants, antioxidants, UV absorbing agents, sunscreen actives, cleansing agents, viscosity modifying agents, film formers, emollients, surfactants, solubilizing agents, preservatives, fragrance, chelating agents, foaming or antifoaming agents, opacifying agents, stabilizing agents, pH adjustors, absorbents, anti-caking agents, slip modifiers, various solvents, solubilizing agents, denaturants, abrasives, bulking agents, emulsion stabilizing agents, suspending agents, colorants, binders, conditioning agent-emollients, surfactant emulsifying agents, biological products, anti-acne actives, anti-wrinkle and anti-skin atrophy actives, skin barrier repair aids, cosmetic soothing aids, topical anesthetics, artificial tanning agents and accelerators, skin lightening actives, antimicrobial and antifungal actives, sebum stimulators, sebum inhibitors, humectants, and/or combinations thereof.
