The present invention relates generally to multi-purpose topical skin compositions that can be used on dry skin, oily skin, normal skin, or combination skin.
There are thousands of skin formulations available to consumers. Further, there are a myriad of different skin types among the population. Such skin types range from normal skin, dry skin, oily skin, and combination skin (e.g., normal/dry, normal/oily, dry/oily). The leads to a confusing and exhaustive search for different products for different applications.
The inventor found a solution to the aforementioned problems. This solution is premised on the use of particular combination of ingredients that synergistically work on all skin-types ranging from normal skin, dry skin, oily skin and combination skin (e.g., normal/dry, normal/oily, dry/oily). In this regard, two separate combinations of natural ingredients were identified and confirmed to be effective across all skin types. Further, the inventor identified sub-combinations of natural ingredients that can be specifically tailored for a given skin-type.
In one instance, for example, the combination of Silybum marianum extract and Momordica grosvenori fruit extract (primary combination) was found to be effective on all skin-types of normal, dry, and oily skin. The addition of Linum usitatissimum seed extract and hydrolyzed algin to the primary combination was found to work well on dry skin. The addition of Psidium guajava fruit extract and Kunzea ericoides leaf extract to the primary combination was found to work well on oily skin. The addition of Plumeria alba flower extract and Nymphea gigantea flower extract to the primary combination was found to work well on normal skin.
In another instance, for example, the combination of Silybum marianum extract and Pseudopterogorgia elisabethae extract (primary combination) was found to be effective on all skin-types of normal, dry, and oily skin. The addition of Linum usitatissimum seed extract and hydrolyzed algin to the primary combination was found to work well on dry skin. The addition of Psidium guajava fruit extract and Spiraea ulmaria extract to the primary combination was found to work well on oily skin. Psidium guajava fruit extract was a hydroglycolic fruit extract. The addition of Plumeria alba flower extract, Euterpe oleraceae fruit extract, and Camellia sinensis leaf extract to the primary combination was found to work well on normal skin. The Plumeria alba flower extract was an aqueous extract.
In one instance, the formulations described in Tables 11-19 can be used as vehicles for any of the combinations of the present invention. Such formulations are generic and can be modified by increasing or decreasing the amount of the various ingredients, which explains why ranges are provided. In particular embodiments, the water can by increased or decreased as needed. Further, although the claims section do not identify the specific formulations in Tables 11-19, it is intended by the inventors that such claims may be made. Therefore, Tables 11-19 are incorporated into the summary of the invention section by reference.

Given the number of various products on the market today and the myriad of different skin-types, a person is oftentimes at a loss to identify an appropriate product. Further, many current products include caustic agents that can irritate skin, leave the skin feeling dry, or leave the skin feeling oily.
The inventors discovered a solution to counteract these issues. In particular, the solution concerns two separate combinations of ingredients obtained from natural sources that have been shown (see examples) to work on different skin types ranging from oily skin, dry skin, or normal skin. Further, subcombinations were found to work particularly well on a given skin type.
These and other non-limiting aspects of the present invention are described in further detail below.
A. Determining Skin-Type
A first step it utilizing the compositions of the present invention can be to determine a user's skin type. It is well known in the cosmetic's field that there are three main skin types: (1) normal skin; (2) dry skin; and (3) oily skin. A fourth skin type is simply a combination of any one of normal, dry, or oily skin (e.g., normal/dry, normal/oily, oily/dry). There are also well-known methods for determining a person's skin type.
For instance, normal skin can be identified as having a smooth texture and no greasy patches or flaky areas. Therefore, a product that can retain skin moisture in its present form can be used to maintain the appearance of normal skin.
As for dry skin, it has a low level of sebum production from sebaceous glands and is prone to irritation or erythema. The appearance of dry skin has a parched look caused by the skin's inability to retain moisture. Oftentimes it feels “tight” and uncomfortable after washing and is prone to chapping, flaking, and cracking. Dry skin can be exacerbated by wind, extremes of temperature and air-conditioning, all of which cause the skin to flake, chap and feel tight. Dry skin typically has a dull appearance. Therefore, a product that deliver appropriate hydration and restore moisture to dry skin can be used to countreract the effects of dry skin.
With respect to oily skin, such skin is shiny, thick and dull colored. It feels oily and has coarse pores and pimples and other unsightly blemishes due to overproduction of sebum from sebaceous glands and from clogged/blocked pores. In this regard, oily skin usually has oil producing sebaceous glands that are overactive and produce more oil than is needed. The oil oozes and gives the skin a greasy shine. The pores are enlarged and the skin has a coarse look. Therefore, a product that can help control skin surface oiliness while also cleansing clogged pores can be used to counteract the effects of oily skin.
As noted above, combination skin is a combination of both oily, dry, and/or normal skin (e.g., normal/dry, oily/dry, normal/oily). For oily/dry skin, there is typically a greasy center panel consisting of nose, forehead and chin (also known as the “T-zone” of a person's face) and a dry panel consisting of cheeks, mouth and the areas around the eyes. Therefore, a product that can control the excess oil production in sebaceous glands in the T-zone while also hydrating the dry skin areas outside of the T-zone can be used for such oily/dry skin.
Once a particular skin-type is identified, a person can then select an appropriate composition to correct or maintain the skin-type.
B. Combination of Silybum marianum and Luo Han Guo Fruit Extracts
The inventors discovered that the combination of Silybum marianum extract and Momordica grosvenori fruit extract was found to be effective on all skin-types of normal, dry, and oily skin.
Milk thistle (Silybum marianum) is a plant native to Southern Europe and Asia. It is known for producing red to purple flowers, shiny pale green leaves with white veins, and fruit. The Silybum marianum extract of the present invention is a hydroalcohlic (water and alcohol denat) extract that includes silymarin as an active ingredient (silymarin is a mixture of flavanonol derivatives that includes silibine, silicristine, silidianin, isosolibine, and isosilicristine). The fruit portion of Silybum marianum includes silymarin. The Silybum marianum extract can be obtained from the fruit portion of this plant by mascerating the fruit pulp and then subjecting the pulp to a hydroalcoholic solution of water and SD alcohol 39-C (alcohol denat.) to obtain the extract.

H. Determining Skin-Type
The primary skin types of humans are normal skin, dry skin, oily skin, and combination skin. Normal skin typically has an even tone, soft, a smooth texture, with no visible pores or blemishes, and no greasy patches or flaky areas. Therefore, a product that can retain skin moisture in its present form can be used to maintain the appearance of normal skin.
Dry skin usually has a low level of sebum and can be prone to irritation. The appearance of dry skin is usually a parched look caused by the skin's inability to retain moisture. Oftentimes it feels “tight” and uncomfortable after washing and is prone to chapping, flaking, and cracking. Dry skin can be exacerbated by wind, extremes of temperature and air-conditioning, all of which cause the skin to flake, chap and feel tight. Dry skin typically has a dull appearance. Therefore, a product that deliver appropriate hydration and restore moisture to dry skin can be used to countreract the effects of dry skin.
Oily skin is typically shiny, thick and dull colored. It typically feels oily and has coarse pores and pimples and other unsightly blemishes. Oily skin usually has oil producing sebaceous glands that are overactive and produce more oil than is needed. The oil oozes and gives the skin a greasy shine. The pores are enlarged and the skin has a coarse look. Therefore, a product that can help control skin surface oiliness while also cleansing clogged pores can be used to counteract the effects of oily skin.
Combination skin is a combination of both oily and dry skin. Usually, there is a greasy center panel consisting of nose, forehead and chin (also known as the “T-zone” of a person's face) and a dry panel consisting of cheeks, mouth and the areas around the eyes. Therefore, a product that can help control the excess oil production in sebaceous glands in the T-zone while also hydrating the dry skin areas outside of the T-zone can be used.

B16 Pigmentation Assay:
Melanogenesis is the process by which melanocytes produce melanin, a naturally produced pigment that imparts color to skin, hair, and eyes. Inhibiting melanogenesis is beneficial to prevent skin darkening and lighten dark spots associated with aging. This bioassay utilizes B16-F1 melanocytes (ATCC), an immortalized mouse melanoma cell line, to analyze the effect of compounds on melanogenesis. The endpoint of this assay is a spectrophotometric measurement of melanin production and cellular viability. B16-F1 melanocytes, cultivated in standard DMEM growth medium with 10% fetal bovine serum (Mediatech) at 37° C. in 10% CO2, were treated with each of the extracts identified in Tables 1-8 for 6 days. Following incubation, melanin secretion was measured by absorbance at 405 nm and cellular viability was quantified.
Collagen Stimulation Assay:
Collagen is an extracellular matrix protein critical for skin structure. Increased synthesis of collagen helps improve skin firmness and elasticity. This bioassay analyzes the effect of extracts on the production of procollagen peptide (a precursor to collagen) by human epidermal fibroblasts. The endpoint of this assay is a spectrophotometric measurement that reflects the presence of procollagen peptide and cellular viability. The assay employs the quantitative sandwich enzyme immunoassay technique whereby a monoclonal antibody specific for procollagen peptide has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any procollagen peptide □present is bound by the immobilized antibody. After washing away any unbound substances, an enzyme-linked polyclonal antibody specific for procollagen peptide is added to the wells. Following a wash to remove any unbound antibody-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of procollagen peptide bound in the initial step using a microplate reader for detection at 450 nm. The color development is stopped and the intensity of the color is measured. Subconfluent normal human adult epidermal fibroblasts (Cascade Biologics) cultivated in standard DMEM growth medium with 10% fetal bovine serum (Mediatech) at 37° C. in 10% CO2, were treated with each of the extracts identified in Tables 1-8 for 3 days. Following incubation, cell culture medium was collected and the amount of procollagen peptide secretion quantified using a sandwich enzyme linked immuno-sorbant assay (ELISA) from Takara (#MK101).
Tumor Necrosis Factor Alpha (TNF-α) Assay:
The prototype ligand of the TNF superfamily, TNF-α, is a pleiotropic cytokine that plays a central role in inflammation. Increase in its expression is associated with an up regulation in pro-inflammatory activity. This bioassay analyzes the effect of extracts on the production of TNF-α by human epidermal keratinocytes. The endpoint of this assay is a spectrophotometric measurement that reflects the presence of TNF-α and cellular viability. The assay employs the quantitative sandwich enzyme immunoassay technique whereby a monoclonal antibody specific for TNF-α has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any TNF-α □present is bound by the immobilized antibody. After washing away any unbound substances, an enzyme-linked polyclonal antibody specific for TNF-α is added to the wells. Following a wash to remove any unbound antibody-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of TNF-α bound in the initial step using a microplate reader for detection at 450 nm. The color development is stopped and the intensity of the color is measured. Subconfluent normal human adult keratinocytes (Cascade Biologics) cultivated in EpiLife standard growth medium (Cascade Biologics) at 37° C. in 5% CO2, were treated with phorbol 12-myristate 13-acetate (PMA, 10 ng/ml, Sigma Chemical, #P1585-1MG) and each of the extracts identified in Tables 1-8 for 6 hours. PMA has been shown to cause a dramatic increase in TNF-α secretion which peaks at 6 hours after treatment. Following incubation, cell culture medium was collected and the amount of TNF-α secretion quantified using a sandwich enzyme linked immuno-sorbant assay (ELISA) from R&D Systems (#DTA00C).
Antioxidant (AO) Assay:
An in vitro bioassay that measures the total anti-oxidant capacity of an extract. The assay relies on the ability of antioxidants in the sample to inhibit the oxidation of ABTS® (2,2′-azino-di-[3-ethylbenzthiazoline sulphonate]) to ABTS®-+ by metmyoglobin. The antioxidant system of living organisms includes enzymes such as superoxide dismutase, catalase, and glutathione peroxidase; macromolecules such as albumin, ceruloplasmin, and ferritin; and an array of small molecules, including ascorbic acid, α-tocopherol, β-carotene, reduced glutathione, uric acid, and bilirubin. The sum of endogenous and food-derived antioxidants represents the total antioxidant activity of the extracellular fluid. Cooperation of all the different antioxidants provides greater protection against attack by reactive oxygen or nitrogen radicals, than any single compound alone. Thus, the overall antioxidant capacity may give more relevant biological information compared to that obtained by the measurement of individual components, as it considers the cumulative effect of all antioxidants present in plasma and body fluids. The capacity of the antioxidants in the sample to prevent ABTS oxidation is compared with that of Trolox, a water-soluble tocopherol analogue, and is quantified as molar Trolox equivalents. Anti-Oxidant capacity kit #709001 from Cayman Chemical (Ann Arbor, Mich. USA) was used as an in vitro bioassay to measure the total anti-oxidant capacity of each of the extracts identified in Tables 1-8. The protocol was followed according to manufacturer recommendations. The assay relied on antioxidants in the sample to inhibit the oxidation of ABTS® (2,2′-azino-di-[3-ethylbenzthiazoline sulphonate]) to ABTS®⋅+ by metmyoglobin. The capacity of the antioxidants in the sample to prevent ABTS oxidation was compared with that Trolox, a water-soluble tocopherol analogue, and was quantified as a molar Trolox equivalent.
ORAC Assay:
Oxygen Radical Absorption (or Absorbance) Capacity (ORAC) of the aromatic skin-active ingredients and compositions can also be assayed by measuring the antioxidant activity of such ingredients or compositions. This assay can quantify the degree and length of time it takes to inhibit the action of an oxidizing agent such as oxygen radicals that are known to cause damage cells (e.g., skin cells). The ORAC value of the aromatic skin-active ingredients and compositions can be determined by methods known to those of ordinary skill in the art (see U.S. Publication Nos. 2004/0109905 and 2005/0163880; Cao et al. (1993)), all of which are incorporated by reference). In summary, the assay described in Cao et al. (1993) measures the ability of antioxidant compounds in test materials to inhibit the decline of B-phycoerythrm (B-PE) fluorescence that is induced by a peroxyl radical generator, AAPH. The extracts identified in Tables 1-8 were subjected to this assay.
Mushroom Tyrosinase Activity Assay:
In mammalian cells, tyrosinase catalyzes two steps in the multi-step biosynthesis of melanin pigments from tyrosine (and from the polymerization of dopachrome). Tyrosinase is localized in melanocytes and produces melanin (aromatic quinone compounds) that imparts color to skin, hair, and eyes. Purified mushroom tyrosinase (Sigma) was incubated with its substrate L-Dopa (Fisher) in the presence or absence of each of the extracts in Tables 1-8. Pigment formation was evaluated by colorimetric plate reading at 490 nm. The percent inhibition of mushroom tyrosinase activity was calculated compared to non-treated controls to determine the ability of test extracts to inhibit the activity of purified enzyme. Test extract inhibition was compared with that of kojic acid (Sigma).
Matrix Metalloproteinase Enzyme Activity (MMP3; MMP9) Assay:
An in vitro matrix metalloprotease (MMP) inhibition assay. MMPs are extracellular proteases that play a role in many normal and disease states by virtue of their broad substrate specificity. MMP3 substrates include collagens, fibronectins, and laminin; while MMP9 substrates include collagen VII, fibronectins and laminin. Using Colorimetric Drug Discovery kits from BioMol International for MMP3 (AK-400) and MMP-9 (AK-410), this assay is designed to measure protease activity of MMPs using a thiopeptide as a chromogenic substrate (Ac-PLG-[2-mercapto-4-methyl-pentanoyl]-LG-OC2H5)5,6. The MMP cleavage site peptide bond is replaced by a thioester bond in the thiopeptide. Hydrolysis of this bond by an MMP produces a sulfhydryl group, which reacts with DTNB [5,5′-dithiobis(2-nitrobenzoic acid), Ellman's reagent] to form 2-nitro-5-thiobenzoic acid, which can be detected by its absorbance at 412 nm (ε=13,600 M-1 cm-1 at pH 6.0 and above 7). The extracts identified in Tables 1-8 were subjected to this assay.
Cyclooxygenase (COX) Assay:
An in vitro cyclooxygenase-1 and -2 (COX-1, -2) inhibition assay. COX is a bifunctional enzyme exhibiting both cyclooxygenase and peroxidase activities. The cyclooxygenase activity converts arachidonic acid to a hydroperoxy endoperoxide (Prostaglandin G2; PGG2) and the peroxidase component reduces the endoperoxide (Prostaglandin H2; PGH2) to the corresponding alcohol, the precursor of prostaglandins, thromboxanes, and prostacyclins. This COX Inhibitor screening assay measures the peroxidase component of cyclooxygenases. The peroxidase activity is assayed colorimetrically by monitoring the appearance of oxidized N,N,N′,N′-tetramethyl-p-phenylenediamine (TMPD). This inhibitor screening assay includes both COX-1 and COX-2 enzymes in order to screen isozyme-specific inhibitors. The Colormetric COX (ovine) Inhibitor screening assay (#760111, Cayman Chemical), was used to analyze the effects of each of the extracts identified in Tables 1-8 on the activity of purified cyclooxygnase enzyme (COX-1 or COX-2). According to manufacturer instructions, purified enzyme, heme and test extracts were mixed in assay buffer and incubated with shaking for 15 min at room temperature. Following incubation, arachidonic acid and colorimetric substrate were added to initiate the reaction. Color progression was evaluated by colorimetric plate reading at 590 nm. The percent inhibition of COX-1 or COX-2 activity was calculated compared to non-treated controls to determine the ability of test extracts to inhibit the activity of purified enzyme.
Lipoxygenase (LO) Assay:
An in vitro lipoxygenase (LO) inhibition assay. LOs are non-heme iron-containing dioxygenases that catalyze the addition of molecular oxygen to fatty acids. Linoleate and arachidonate are the main substrates for LOs in plants and animals. Arachadonic acid may then be converted to hydroxyeicosotrienenoic (HETE) acid derivatives, that are subsequently converted to leukotirenes, potent inflammatory mediators. This assay provides an accurate and convenient method for screening lipoxygenase inhibitors by measuring the hydroperoxides generated from the incubation of a lipoxygenase (5-, 12-, or 15-LO) with arachidonic acid. The Colorimetric LO Inhibitor screening kit (#760700, Cayman Chemical) was used to determine the ability of each of the extracts identified in Tables 1-8 to inhibit enzyme activity. Purified 15-lipoxygenase and test extracts were mixed in assay buffer and incubated with shaking for 10 min at room temperature. Following incubation, arachidonic acid was added to initiate the reaction and mixtures incubated for an additional 10 min at room temperature. Colorimetric substrate was added to terminate catalysis and color progression was evaluated by fluorescence plate reading at 490 nm. The percent inhibition of lipoxyganse activity was calculated compared to non-treated controls to determine the ability of test extracts to inhibit the activity of purified enzyme.
Elastase Assay:
EnzChek® Elastase Assay (Kit#E-12056) from Molecular Probes (Eugene, Oreg. USA) was used as an in vitro enzyme inhibition assay for measuring inhibition of elastase activity for each of the extracts identified in Tables 1-8. The EnzChek kit contains soluble bovine neck ligament elastin that has been labeled with dye such that the conjugate's fluorescence is quenched. The non-fluorescent substrate can be digested by elastase or other proteases to yield highly fluorescent fragments. The resulting increase in fluorescence can be monitored with a fluorescence microplate reader. Digestion products from the elastin substrate have absorption maxima at ˜505 nm and fluorescence emission maxima at ˜515 nm. The peptide, chloromethyl ketone, is used as a selective, collective inhibitor of elastase when utilizing the EnzChek Elastase Assay Kit for screening for elastase inhibitors.
Additional assays that can be used to determine the efficacy of any one of the compositions disclosed throughout the specification and claims can be determined by methods known to those of ordinary skill in the art. The following are non-limiting assays that can be used in the context of the present invention. It should be recognized that other testing procedures can be used, including, for example, objective and subjective procedures.
Oil Control Assay:
An assay to measure reduction of sebum secretion from sebaceous glands and/or reduction of sebum production from sebaceous glands can be assayed by using standard techniques known to those having ordinary skill in the art. In one instance, the forehead can be used. A composition of the present invention can be applied to one portion of the forehead once or twice daily for a set period of days (e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, or more days), while another portion of the forehead is not treated with the composition. After the set period of days expires, then sebum secretion can be assayed by application of fine blotting paper to the treated and untreated forehead skin. This is done by first removing any sebum from the treated and untreated areas with moist and dry cloths. Blotting paper can then be applied to the treated and untreated areas of the forehead, and an elastic band can be placed around the forehead to gently press the blotting paper onto the skin. After 2 hours the blotting papers can be removed, allowed to dry and then transilluminated. Darker blotting paper correlates with more sebum secretion (or lighter blotting paper correlates with reduced sebum secretion.
Erythema Assay:
An assay to measure the reduction of skin redness can be evaluated using a Minolta Chromometer. Skin erythema may be induced by applying a 0.2% solution of sodium dodecyl sulfate on the forearm of a subject. The area is protected by an occlusive patch for 24 hrs. After 24 hrs, the patch is removed and the irritation-induced redness can be assessed using the a* values of the Minolta Chroma Meter. The a* value measures changes in skin color in the red region. Immediately after reading, the area is treated with a composition of the present invention. Repeat measurements are taken at regular intervals to determine the formula's ability to reduce redness and irritation.
Skin Moisture/Hydration Assay:
Skin moisture/hydration benefits can be measured by using impedance measurements with the Nova Dermal Phase Meter. The impedance meter measures changes in skin moisture content. The outer layer of the skin has distinct electrical properties. When skin is dry it conducts electricity very poorly. As it becomes more hydrated increasing conductivity results. Consequently, changes in skin impedance (related to conductivity) can be used to assess changes in skin hydration. The unit can be calibrated according to instrument instructions for each testing day. A notation of temperature and relative humidity can also be made. Subjects can be evaluated as follows: prior to measurement they can equilibrate in a room with defined humidity (e.g., 30-50%) and temperature (e.g., 68-72° C.). Three separate impedance readings can be taken on each side of the face, recorded, and averaged. The T5 setting can be used on the impedance meter which averages the impedance values of every five seconds application to the face. Changes can be reported with statistical variance and significance.
Skin Clarity and Reduction in Freckles and Age Spots Assay:
Skin clarity and the reduction in freckles and age spots can be evaluated using a Minolta Chromometer. Changes in skin color can be assessed to determine irritation potential due to product treatment using the a* values of the Minolta Chroma Meter. The a* value measures changes in skin color in the red region. This is used to determine whether a composition is inducing irritation. The measurements can be made on each side of the face and averaged, as left and right facial values. Skin clarity can also be measured using the Minolta Meter. The measurement is a combination of the a*, b, and L values of the Minolta Meter and is related to skin brightness, and correlates well with skin smoothness and hydration. Skin reading is taken as above. In one non-limiting aspect, skin clarity can be described as L/C where C is chroma and is defined as (a2+b2)1/2.
Skin Dryness, Surface Fine Lines, Skin Smoothness, and Skin Tone Assay:
Skin dryness, surface fine lines, skin smoothness, and skin tone can be evaluated with clinical grading techniques. For example, clinical grading of skin dryness can be determined by a five point standard Kligman Scale: (0) skin is soft and moist; (1) skin appears normal with no visible dryness; (2) skin feels slightly dry to the touch with no visible flaking; (3) skin feels dry, tough, and has a whitish appearance with some scaling; and (4) skin feels very dry, rough, and has a whitish appearance with scaling. Evaluations can be made independently by two clinicians and averaged.
Clinical Grading of Skin Tone Assay:
Clinical grading of skin tone can be performed via a ten point analog numerical scale: (10) even skin of uniform, pinkish brown color. No dark, erythremic, or scaly patches upon examination with a hand held magnifying lens. Microtexture of the skin very uniform upon touch; (7) even skin tone observed without magnification. No scaly areas, but slight discolorations either due to pigmentation or erythema. No discolorations more than 1 cm in diameter; (4) both skin discoloration and uneven texture easily noticeable. Slight scaliness. Skin rough to the touch in some areas; and (1) uneven skin coloration and texture. Numerous areas of scaliness and discoloration, either hypopigmented, erythremic or dark spots. Large areas of uneven color more than 1 cm in diameter. Evaluations were made independently by two clinicians and averaged.
Clinical Grading of Skin Smoothness Assay:
Clinical grading of skin smoothness can be analyzed via a ten point analog numerical scale: (10) smooth, skin is moist and glistening, no resistance upon dragging finger across surface; (7) somewhat smooth, slight resistance; (4) rough, visibly altered, friction upon rubbing; and (1) rough, flaky, uneven surface. Evaluations were made independently by two clinicians and averaged.
Skin Smoothness and Wrinkle Reduction Assay with Methods Disclosed in Packman et al. (1978):
Skin smoothness and wrinkle reduction can also be assessed visually by using the methods disclosed in Packman et al. (1978). For example, at each subject visit, the depth, shallowness and the total number of superficial facial lines (SFLs) of each subject can be carefully scored and recorded. A numerical score was obtained by multiplying a number factor times a depth/width/length factor. Scores are obtained for the eye area and mouth area (left and right sides) and added together as the total wrinkle score.
Skin Firmness Assay with a Hargens Ballistometer:
Skin firmness can be measured using a Hargens ballistometer, a device that evaluates the elasticity and firmness of the skin by dropping a small body onto the skin and recording its first two rebound peaks. The ballistometry is a small lightweight probe with a relatively blunt tip (4 square mm-contact area) was used. The probe penetrates slightly into the skin and results in measurements that are dependent upon the properties of the outer layers of the skin, including the stratum corneum and outer epidermis and some of the dermal layers.
Skin Softness/Suppleness Assay with a Gas Bearing Electrodynamometer:
Skin softness/suppleness can be evaluated using the Gas Bearing Electrodynamometer, an instrument that measures the stress/strain properties of the skin. The viscoelastic properties of skin correlate with skin moisturization. Measurements can be obtained on the predetermined site on the cheek area by attaching the probe to the skin surface with double-stick tape. A force of approximately 3.5 gm can be applied parallel to the skin surface and the skin displacement is accurately measured. Skin suppleness can then be calculated and is expressed as DSR (Dynamic Spring Rate in gm/mm).
Appearance of Lines and Wrinkles Assay with Replicas:
The appearance of lines and wrinkles on the skin can be evaluated using replicas, which is the impression of the skin's surface. Silicone rubber like material can be used. The replica can be analyzed by image analysis. Changes in the visibility of lines and wrinkles can be objectively quantified via the taking of silicon replicas form the subjects' face and analyzing the replicas image using a computer image analysis system. Replicas can be taken from the eye area and the neck area, and photographed with a digital camera using a low angle incidence lighting. The digital images can be analyzed with an image processing program and the are of the replicas covered by wrinkles or fine lines was determined.
Surface Contour of the Skin Assay with a Profilometer/Stylus Method:
The surface contour of the skin can be measured by using the profilometer/Stylus method. This includes either shining a light or dragging a stylus across the replica surface. The vertical displacement of the stylus can be fed into a computer via a distance transducer, and after scanning a fixed length of replica a cross-sectional analysis of skin profile can be generated as a two-dimensional curve. This scan can be repeated any number of times along a fix axis to generate a simulated 3-D picture of the skin. Ten random sections of the replicas using the stylus technique can be obtained and combined to generate average values. The values of interest include Ra which is the arithmetic mean of all roughness (height) values computed by integrating the profile height relative to the mean profile height. Rt which is the maximum vertical distance between the highest peak and lowest trough, and Rz which is the mean peak amplitude minus the mean peak height. Values are given as a calibrated value in mm. Equipment should be standardized prior to each use by scanning metal standards of know values. Ra Value can be computed by the following equation: Ra=Standardize roughness; lm=the traverse (scan) length; and y=the absolute value of the location of the profile relative to the mean profile height (x-axis).
MELANODERM™ Assay:
In other non-limiting aspects, the efficacy of the compositions of the present invention can be evaluated by using a skin analog, such as, for example, MELANODERM™. Melanocytes, one of the cells in the skin analog, stain positively when exposed to L-dihydroxyphenyl alanine (L-DOPA), a precursor of melanin. The skin analog, MELANODERM™, can be treated with a variety of bases containing the compositions and whitening agents of the present invention or with the base alone as a control. Alternatively, an untreated sample of the skin analog can be used as a control.
All of the skin-active ingredients, compositions, or methods disclosed and claimed in this specification can be made and executed without undue experimentation in light of the present disclosure. While the skin-active ingredients, compositions, or methods of this invention have been described in terms of particular embodiments, it will be apparent to those of skill in the art that variations may be applied to the skin-active ingredients, compositions, or methods and in the steps or in the sequence of steps of the method described herein without departing from the concept, spirit and scope of the invention.
