DETAILED DESCRIPTION

[0022] Proper skin care is important for heath and cosmetic reasons. Skin is a vital organ and a breakdown in the skin can adversely affect the skin's function as a barrier and make it susceptible to infection. A breakdown in the skin can also be very painful, such as the case of excessively dry skin. Visual irregularities and fine lines and wrinkles in the skin can adversely affect a person's confidence and other people's perceptions.

[0023] There remains a need for improved methods of treating skin and maintaining or improving its health and cosmetic features. It is against this background that the present disclosure is made.

[0024] Surprisingly, it has been found that using a micro-exfoliation tool together with selected skin care agents results in improved skin health and appearance. It was also surprising that skin compositions containing retinaldehyde in place of retinol or adapalene resulted in faster and/or greater improvement in skin characteristics, including, firmness, elasticity, fine lines and wrinkles, skin texture, dullness, dyschromia, and skin tone. Further, skin compositions containing retinaldehyde were much more tolerable when compared with other skin compositions.

[0025] It was also surprisingly found that the skin compositions containing retinaldehyde, in place of benzoyl peroxide, was tolerable and effective against mild to moderate acne vulgaris. The skin treated with compositions described herein saw a reduction or elimination of acne.

[0026] These and other embodiments will be apparent to those of skill in the art and others in view of the following detailed description. The present disclosure generally relates to skin treatment using a retinaldehyde containing composition and/or a micro- exfoliation tool and/or additional selected skin care agents. While not wanting to be bound by theory, it is believed that the combination of the micro-exfoliation tool and the selected skin care agents increases the uptake of the selected skin care agents by the epidermis (outer layer of skin) than if the skin care agent was just placed on top of the epidermis. This is believed to be in part because the micro-exfoliation tool increases the surface area of the epidermis by creating micro pores or holes in the skin, thereby allowing a greater number of skin cells on the epidermis to contact and benefit from the selected skin care agent. One result of this is that a user can see improved results in a shorter period of time.

[0189] Example 9: Clinical Study Evaluating Efficacy and Tolerance of IRS compared with Adapalene Gel

[0190] The objective of the study is to evaluate and compare the anti-aging efficacy and tolerability of 0.1% Adapalene compared to Intensive Renewing Serum over a 12-week period when used by women with mild to moderate lines and wrinkles, dullness and moderate dyschromia.

[0191] Subjects reported to the facility at Baseline for Expert Grader assessments of various facial photoaging and irritation parameters, subjective assessments of facial irritation, digital imaging of the face, replica sampling of the crow's foot area, capacitance and firmness/elasticity measurements of the face and completed a self-assessment questionnaire. Subjects were randomized to receive 1 of 2 investigational products for treatment to the entire face for 12 weeks. Subjects returned to the lab at Week 2 and Week 4 to have Expert Grader assessments, digital imaging and self-assessments repeated. At Weeks 8 and 12, subjects returned for Expert Grader assessments, digital imaging, replica sampling, capacitance and firmness/elasticity measurements and self-assessments.

[0192] Treatments & Procedures:

[0193] Expert Grader Assessments: In addition to screening and selecting the final panel, an Expert Grader assessed the face of each subject for various irritation and efficacy parameters at Baseline and after 2, 4, 8 and 12 weeks of treatment. The scale that was used for each assessment parameter (unless otherwise indicated) is: 0=none, 1-3= mild, 4- 5=moderate, 7-9=severe.

[0194] Irritation parameters: The Expert Grader assessed the face of each subject at each time point for the following irritation parameters using a 0-9 scale: Erythema, Dryness, Scaling, and Edema. Using a 0-9 scale, subjects were asked to rate their amount of: Burning, Stinging, Itching, Tightness, and Dryness.

[0195] Efficacy parameters: The assessments of efficacy were made using methods that would provide the Sponsor the most information on changes in the subject's skin over time. The methods that the Expert Grader used to assess efficacy are as follows: 1. Live Grading: Absolute scores from viewing the subject's face were assigned using a 0-9 scale. Live grades were conducted at each time point. 2. Baseline Aided Grading: Absolute scores from viewing the subject's face were assigned using a 0-9 scale at the Baseline visit and the Expert Grader used the subject's Baseline photo for reference at follow-up visits. Baseline aided grading was conducted at each time point other than at Baseline. 3. Comparison Grading from Photos: Comparison grading was performed after the conclusion of the study. The Expert Grader compared the photos from each time point to Baseline for improvement/worsening using the below scale: -4=Marked worsening, -3=Moderate worsening, -2=Mild worsening, -l=Barely perceptible worsening, -0.1=Forced choice worsening, 0=No change, 0.1=Forced choice improvement, l=Barely perceptible improvement, 2=Mild improvement, 3=Moderate improvement, and 4=Marked improvement.

[0196] The following efficacy parameters were assessed by the Expert Grader along with the assessment method(s) are listed: 1. Skin Texture (softness/smoothness) [tactile]: Live grading, 2. Skin Texture [visual]: Live grading/Baseline aided, 3. Fine Lines (eye area including crow's feet): Live grading/Baseline aided/Comparison scores from photos, 4. Wrinkles (eye area, including crows feet): Live grading, Baseline aided, Comparison scores from photos, 5. Pore appearance: Comparison scores from photos, 6. Firmness: Live grading, 7. Sagging (nasolabial fold area): Comparison scores from photos, 8. Discrete hyperpigmentation: Comparison scores from photos, 9. Mottled hyperpigmentation: Comparison scores from photos, 10. Skin tone evenness: Comparison scores from photos, 11. Radiance/luminosity/glow (defined as Dull to luminous/shiny): Live grading, 12. Sallowness (sallow to rosy): Live grading/ Baseline aided, 13. Overall healthy skin appearance: Comparison scores from photos, 14. Overall photodamage: Live grading/Baseline aided, 15. Pinch recoil (under the eye): Live grading (For this assessment, a 0-9 score will not be assigned. Per the Sponsor, the evaluator will pinch the subject's skin at the designated site using the thumb and forefinger and hold the skin in place for approximately 2 seconds. A stopwatch will be started upon release and the time required for the subject's skin to return to its original conformation will be measured to the nearest tenth of a second. A decrease in pinch recoil times over time indicates an improvement in skin "bounce-back" or elasticity/resiliency.). For the above efficacy parameters, parameters that indicate live grades were completed at Baseline and after 2, 4, 8 and 12 weeks of treatment. For the parameters that indicate grading of photos, the grading was completed after the conclusion of the study.

[0197] Digital Photography: Digital images using visible, cross-polarized, parallel, and UV lighting were taken of each subject's face using a custom photography system. Images were taken of each subject's face (Left, Right and Center views) at Baseline and again after 2, 4, 8 and 12 weeks of treatment.

[0198] Skin Surface Impressions: Silflo impressions of the left crow's foot area were made by a trained cyberDERM technician at Baseline (prior to treatment) and again after 8 and 12 weeks of treatment. The sampled site on each individual subject was delineated by affixing an adhesive ring using extreme care not to alter the surface tension across the skin. Skin impressions were obtained with silicon dental impression material. A thin layer of freshly prepared material was gently spread over the bounded area of the ring using a stainless steel spatula. Within 2 to 3 minutes, the material should polymerize after which time the ring together with the impression was lifted from the skin. Each specimen was immediately coded as to subject, time point and test site. A Digital Image Analysis System consisting of Visioline VL 650 hardware (Courage + Khazaka, Cologne, Germany) with a specialized image analysis software package (Image-Pro Premiere) was used. The resulting images consisted of a series of shadows that directly corresponded to the pattern of wrinkles. During analysis, one can measure changes in skin surface topography by selecting a gray level threshold that allows one to directly determine the projected area of the shadowed region associated with the wrinkles. Changes in skin surface topography can be quantified by measuring the dimensions of the individual shadows as well as the overall area of shadowing.

[0199] Corneometer® CM 825: All measurements were taken following a minimum 25 -minute acclimation period in a controlled environment with the relative humidity maintained at less than 50% and temperature maintained at 19-22°C. The measuring principle of the Courage + Khazaka Corneometer® CM 825 is based on capacitance measurement of a dielectric medium. Any change in the dielectric constant due to skin surface hydration variation alters the capacitance of a precision measuring capacitor. The measurement can detect even slight changes in the hydration level. The reproducibility of the measurement is very high and the measurement time is very short (1 s). The instrument technician took five measurements from the left and right sides of the face at the nexus where a line drawn lateral from the nostril meets a line drawn vertical from the corner of the eye at Baseline (prior to treatment) and again after 8 and 12 weeks of treatment. The average value was computed for each site after each measurement session.

[0200] DermaLab® Suction Cup: All measurements were taken following a minimum 25 -minute acclimation period in a controlled environment with the relative humidity maintained at less than 50% and temperature maintained at 19-22°C. A DermaLab® USB with a Suction Cup was used to evaluate skin elasticity. The suction probe which was placed on the test site is capable of producing a vacuum up to 650mbar. Within the suction chamber there is a height detection system to measure how much the skin has moved as a result of the applied vacuum. The measuring aperture is 10mm in diameter and the probe itself has an ultra low weight of approximately 7g for minimum skin bias. The probe was secured to the panelist's site using an adhesive ring. When the suction pump is activated it creates a vacuum that draws the skin into the chamber and the height to which the skin is drawn in is recorded in the software and used to calculate elasticity parameters. The skin is then allowed to relax for 1 second before the vacuum resumes for a total of 5 cycles. Parameters related to elasticity and firmness were reported. The instrument technician took one measurement from the left and right sides of the face at the nexus where a line drawn lateral from the nostril meets a line drawn vertical from the corner of the eye at Baseline (prior to treatment) and again after 8 and 12 weeks of treatment.

[0201] Self-Assessment Questionnaires: Subjects completed Sponsor-supplied self-assessment questionnaires (Appendix D) at Baseline and after 2, 4, 8 and 12 weeks of treatment.

[0202] Baseline Questionnaire included questions about skin type, the frequency of acne pimples or breakouts, types and names of products used in their regular skincare routine, effects of other products on skin.

[0203] Week 2 Questionnaire included questions about what the subject liked and disliked about the test product, if the subject experienced any irritation (burning, stinging, itching, tightness, dryness, redness, etc.) while using the test product for the past 2 weeks.

[0204] Week 4 Questionnaire included questions about what the subject liked and disliked about the test product, if the subject experienced any irritation (burning, stinging, itching, tightness, dryness, redness, etc.) while using the test product for the past 2 weeks, and was asked to rate the level of agreement with the following statements compared to starting the study (baseline): a. Skin looks healthier, b. Skin feels healthier, c. My skin looks clearer, d. Pores appear smaller, e. I experienced fewer pimples/breakouts, f. Skin feels firmer, g. Skin's texture looks smoother, h. Age spots/darks spots are less visible, i. Skin's texture is visibly more even, j . Skin feels smoother, k. Skin is visibly more radiant, 1. Skin looks visibly younger, m. Skin feels younger, n. Skin tone/color is visibly more even, o. I see fewer lines/wrinkles, p. The product reduced the appearance of nose to mouth lines (nasolabial folds), q. Skin is visibly less red, r. Oily and dry patches feel more balanced, s. Makeup stays fresh all day after using the product, t. Makeup goes on much better after using the test product, u. I like the overall appearance of my skin, v. The test product did not leave my skin feeling tight or uncomfortable, w. I liked using the test product nightly, and x. I liked using the test product.

[0205] Weeks 8 and 12 Questionnaires included questions similar to the week 4 questionnaire, as well as whether the subject was satisfied with their results and would they continue to use the product and recommend product to a friend. [0206] Investigational Products: The following investigational products (test product and benchmark) were supplied by the Sponsor and were labeled as follows:

[0207] Product C: REDEFINE Intensive Renewing Serum,

[0208] Product N: Differin 0.10% Adapalene

[0209] Treatment Procedures: approximately 20-25 subjects assigned to each product per randomization.

[0210] Product C: Morning instructions: Follow your regular morning skincare routine. Evening instructions: Product C should be used once daily in the evening, after your regular cleanser. Open a capsule by twisting off the tail end of one capsule. Apply the serum over your entire face, including under the eyes and crow's feet. Do not apply on eyelids. Avoid getting into eyes, In case of inadvertent eye contact, rinse eyes with plenty of water to remove product from eyes. Do not wash off from skin. Use one capsule per night. Follow with the rest of your evening skin care Regimen. Note: make sure that no water gets into the jar and that your hands are dry before use. Please ensure the jar is tightly closed after each use.

[0211] Product N: Morning instructions: Follow your regular morning skincare routine. Evening instructions: Product N should be used once daily in the evening, after your regular cleanser. Clean the skin gently with your regular cleanser and pat dry before applying Product N. Cover the entire face, including under the eyes and crow's feet, with a thin layer. Do not apply on eyelids. Avoid product contact with eyes, lips and mouth. If contact occurs, immediately flush the area with water. Do not wash off. Wash hands after use. Do not use more than one time a day. Follow with the rest of your evening skin care Regimen.

[0212] The results of the tolerability assessments demonstrates Intensive Renewing Serum was well tolerated and more tolerated than Adapalene. These assessments were measured subjectively and objectively as described above.

[0213] Subjective Results- Burning: somewhat greater degree of perceived burning with Adapalene, Stinging: somewhat greater degree of perceived stinging with Adapalene, Itching: little to no difference in perceived itching between products, Dryness/Tightness: slightly greater perception of dryness/tightness with Adapalene, most notably at Week 4.

[0220] Table 27 provides the results of the self-assessment questionnaires, which provided information regarding the subject' s overall experience with the products. Subjects using the Intensive Renewing Serum were much more satisfied with their results after 12 weeks.

Table 27: Summary of User Experience

[0221] Example 10: Clinical study of the safety and efficacy of IRS for acne.

[0222] The objective of this study was to evaluate the efficacy and tolerance of the Intensive Renewing Serum with a skin care regimen when used by women with mild to moderate acne vulgaris over a twelve week time period. [0223] This was a single center, single cell (target completion n=25), nonrandomized 12 week clinical study of female subjects ages 22-45 years of age with a Fitzpatrick Skin Type of I- VI with mild to moderate acne vulgaris (defined by an IGA score of 2-3) on the face with a minimum of 5 inflammatory lesions (jawline to hairline), mild to moderate skin clarity (defined by a score of 3-6 on a 0-9 scale) and mild to moderate crow's feet wrinkles (defined by a score of 1-6 on a 0-9 scale). A minimum of 50% of subjects had a moderate degree of crow's feet wrinkles (defined by a score of 4-6 on a 0-9 scale) and this group of subjects underwent analysis skin surface impressions and ultrasound measurements.

[0224] Clinical Evaluations: At the Baseline, Week 2, Week 4, Week 8, and Week 12 visits the Principal Investigator assessed the following clinical grading parameters:

[0225] 1. Investigator Global Acne Assessment Score: 0=Clear, residual hyperpigmentation and erythema may be present; l=Almost clear, a few scattered comedones and a few (less than five) small papules; 2=Mild, easily recognizable; less than half the face is involved, many comedones and many papules and pustules; 3=Moderate, more than half of the face is involved, numerous comedones, papules, and pustules; 4=Severe, entire face is involved, covered with comedones, numerous papules and pustules, and few nodules and cysts; 5 Very severe, highly inflammatory acne covering the face; with nodules and cysts present.

[0226] 2. Global Lesion Count: At the Baseline, Week 2, Week 4 and Week 8 visits each subject had their inflammatory lesions (papules and pustules) and noninflammatory lesions (open and closed comedones) and macules (PIH/PIE) separately counted and recorded for their forehead, left cheek, chin (including the area above the upper lip), and right cheek. The counts in each section were added up to give a total lesion count number.

[0227] 3. Clinical Grading Parameters: At the Baseline, Week 2, Week 4, Week 8 and Week 12 visits clinical grading parameters (Overall Healthy Appearance of Skin Condition, Even Skin Tone, Skin Texture*, Global Fine Lines, Pore Appearance, Global Wrinkles, Skin Clarity, Fine Lines - Crow's Feet and Under Eye, Radiance, Coarse Wrinkles - Crow's Feet and Under Eye, Oiliness, Overall Photodamage„Plumpness/Fullness, Skin Firmness* [*assessed by touch]) were assessed using a 0-9 modified Griffiths scale where 0=none, l-3=mild, 4- 6=moderate and 7-9=severe. In addition, sub-orbital skin elasticity was assessed via pinch-recoil measurement. The Principal Investigator gently pinched the skin of the subject's lower eyelid using the thumb and forefinger. The Principal Investigator held the skin in place for approximately 3 seconds. A decrease in pinch-recoil times indicated an improvement in skin elasticity/resiliency. The pinch-recoil response was graded on a 0-9 scale where 0= none, 1-3 = mild skin laxity, 4-6 = moderate skin laxity, and 7-9 = severe skin laxity.

[0228] 4. Clinical Tolerance Scores and Safety Endpoints: At the Baseline, Week 2, Week 4, Week 8 and Week 12 visits the following parameters were assessed by the Principal Investigator or by the subject (via interview by the Principal Investigator) using a 0- 3 scale where 0 = None, 1-1.5 = Mild, 2-2.5 = Moderate and 3-3.5 =Severe). Principal Investigator: erythema, edema, dryness, scaling, and peeling. Subject: burning/itching, itching, and tightness.

[0229] Sebumeter Measurements: At the Baseline, and Week 8 visits a Sebumeter was used to assess sebum quantities on the skin surface (skin oiliness). The Sebumeter used grease spot photometry for the qualification of sebum. A single reading was taken from all subjects at the center of the forehead and on the center of the left cheek (to measure outside the T-zone area). The same placement was used for all readings for each subject by placing a small probe (similar size to the eraser on a pencil) on the skin. No pain, discomfort, or known documented ill effects were associated with this procedure. The Week 8 measurements was taken at about the same time (+/- 3 hours) as the Baseline visit to assure the same level of sebaceous gland activity.

[0230] Ultrasound Measurements: At the Baseline visit 15 subjects were chosen by the Principal Investigator who had moderate crow's feet wrinkles (score of 4-6 on a 0-9 scale) to have Ultrasound measurements performed of both left and right crow's feet areas at the Baseline and Week 8 visits. The Ultrasound Echography was used to measure the skin thickness. This was done with a DermaScan C (Cortex Technology, Hadsund, Denmark). This consisted of a hand held probe that contained an ultrasonic transducer which was interfaced to a specially configured computer. The probe had a built-in closed water path and was capable of scanning an area of the skin surface 12.1mm in length. To ensure good transmission of the ultrasound signals, a water compatible ultrasound gel (Dane Gel, cyberDerm, Inc. Broomall, PA) was used as a skin contact medium. The scanner processed four frames per second and displayed the results as a live-B-mode image. A standard medium focus 20MHz transducer with maximum focal distance of 13mm was employed. With this transducer, the axial system resolution was 60 μπι and the lateral system resolution was 150 μπι. Gain settings were selected that produced the best visualization of the test site, this gain setting was recorded for each person and was used for subsequent visits so changes in echo strength could accurately be evaluated. [0231] Cutometer Measurements: At the Baseline, Week 4 and Week 8 visits all subjects had a single cutometer measurement conducted on the right ocular bone directly beneath the center of the eye. The cutometer measured elasticity (skin firmness) of the upper skin layers using a negative pressure that was created in the device and applied perpendicularly to the skin surface; in the time strain mode, skin was drawn in to the aperture of the probe by a constant vacuum that was applied to the skin surface fir a defined time and then the vacuum was reduced to 0 mbar so the skin could return to its original shape. The penetration depth of the skin in the probe was measured by a non-contact optical measuring system. Extensibility (R0), resiliency (R2), pure elasticity (R5), and biological elasticity (R7) parameters were all recorded for each subject.

[0232] Corneometer Measurements: At the Baseline, Week 2, Week 4 and Week 8 visits all subjects had corneometer measurements of the left cheek. The corneometer was used to measure the moisture content of the skin. This measurement was performed by having a small open probe placed on the skin surface. Three single readings were taken per subject on the center of the left cheek (at the intersection of lines extending up from the corner of the mouth and horizontally across the bottom of the nose) at each visit.

[0233] Skin Surface Impressions: At the Baseline, Week 8 and Week 12 visits skin surface impressions (replicas) were performed on both left and right crow's feet areas on up to 15 subjects chosen by the Principal Investigator at Baseline. Silflo impressions performed at each visit. The skin impressions were obtained with silicone dental impression material. A thin layer of freshly prepared material was gently spread over the bounded area of a ring using a stainless steel spatula. The material polymerized after about 2-3 minutes after which the ring together with the impression was lifted from the skin. Each specimen was immediately coded with the subject's number, time point and test site, then stored for analysis. A Digital Image Analysis System consisting of Visioline VL 650 hardware (Courage + Khazaka, Cologne, Germany) with a specialized image analysis software package (Image-Pro Premiere) was used for impression analysis. This system consisted of a high resolution black and white video camera interfaced with a computer. An LED illuminator was used to cross illuminate the specimen perpendicular to the major lines which accentuated the surface details. Images were made with the illuminator at a fixed angle and distance while the specimen was positioned on a turntable. The resulting images consisted of a series of shadows that directly corresponded to the pattern of wrinkles. During the analysis the changes in the skin surface topography were measured by selecting a gray level threshold that allowed the projected area of the shadowed region associated with the wrinkles to be directly determined. Changes in the skin surface topography were quantified by measuring the dimensions of the individual shadows as well as the overall area of shadowing.

[0234] Subject Questionnaires: At Baseline, Week 2, Week 4, Week 8 and Week 12 visits, subjects completed a self-assessment questionnaire while seated in front of a mirror.

[0235] Study Products: 1. Wash (U BLEMISH Acne Treatment Sulfur Wash), 2. Toner (UNBLEMISH Clarifying Toner), 3. Treatment (UNBLEMISH Dual Intensive Acne Treatment), 4. SPF (UNBLEMISH oil Control Lotion SPF 20), 5. Hydration Serum (ENHANCEMENTS Active Hydration Serum), 6. Night serum (REDEFINE Intensive Renewing Serum).

[0236] Product Application: Each subject received a skin regimen (Wash, Toner, Treatment, and SPF) and a Night Serum at the Baseline visit for daily morning and evening applications for 12 weeks. Subjects received a Hydration Serum for evening applications Weeks 9-12. Subjects applied the skin regimen to their full face following the instructions. Both written and verbal instructions were provided to each subject prior to their first application.

[0238] Conclusion: Twenty three (23) subjects aged 22 to 45 years completed this twelve (12) week study (target accrual was twenty five). All received a skin care regimen (Wash, Toner, Acne Treatment, and SPF) plus serums (Night and Hydration). Statistically significant improvement and tolerability was demonstrated over the twelve (12) week study period.

[0239] Acne improved significantly with reduction of IGA and Inflammatory & Non-Inflammatory Lesion Counts. Statistically significant improvement of IGA was seen as early as Week 2. Inflammatory Lesion Counts and Non-inflammatory Lesion Counts demonstrated statistically significant reduction by Week 2 and Week 4, respectively.

[0240] All clinical grading parameters demonstrated statistically significant improvement except Pinch Recoil. Eight (8) of fifteen (15) parameters demonstrated statistically significant reduction (improvement) as early as Week 2 and four (4) of fifteen (15) by Week 4. Statistically significant improvement was seen in Skin Firmness and Crow's Feet & Under-eye Course Lines by Week 8 and Week 12, respectively.

[0241] Corneometer measurements from the central and left cheek demonstrated statistically significant improvement in moisture content (hydration) at Week 8. Cutometer measurements from the right suborbital face demonstrated improvement in elasticity (skin firmness) measurements. While Pure and Biological Elasticity demonstrated improvement, Extensibility achieved statistically significant improvement as both Week 2 and Week 4. Minimal changes were seen for Resiliency. Sebumeter measurements from the central forehand and left cheek demonstrated 18% and 2% sebum reduction at Week 8, respectively. These changes were not statistically significant. Image analysis of Skin Surface Impressions (replicas) of the crow's feet areas demonstrated statistically significant reduction in Shadow Area (lines) at Week 8 (24% reduction) and Week 12 (33% reduction). Ultrasound measurements of the crow's feet areas showed no statistically significant changes in Thickness and Intensity at Week 8 and Week 12 compared to baseline.

[0242] Product-related skin irritation was reported by one subject who did not complete the study and statistically significant Dryness and near statistically significant Peeling was noted at Week 2. For the remainder of the 12 week study, clinical tolerance scores demonstrated no statistically significant changes.

[0243] Subject Questionnaire responses revealed statistically significant favorable responses in the majority of questions.

[0244] In summary, the treatment regimen plus serums significantly improved acne and appearance and was well tolerated.

[0245] Example 11 : Effect of 6 Test Materials on the Activation of Retinoic Acid Response Element (RARE) transcription factor pathway.

[0246] Objective: Retinoic Acid Receptor (RAR) controls gene transcription by binding to Retinoid Acid Response Elements (RAREs) in DNA. This process is modulated by all trans retinoic acid (ATRA) - a compound with well-established anti-aging skin benefits. Despite these benefits ATRA also exhibits undesirable side effects, and the discovery of ATRA functional analogues with improved therapeutic and/or cosmetic activity profile is highly desirable. Cignal RARE Reporter Assay® is designed to screen for such compounds using cell cultures. The objective of this project was to test 6 compounds (retinoic acid (ATRA), retinol, vitamin A palmitate, retinal, 10%w/w Near-1 in dimethylisosorbide, and 10%w/w retionoid ester in dimethylisosorbide) for the ability to activate RARE in this Cignal RARE Reporter Assay model.

[0247] Materials & Methods: The experiments were performed using HEK293 cells (Sigma, St. Louis, MO; cat.# 85120602) seeded at 50,000 per well in a 96 well black- wall tissue culture plate. Cells were transfected by mixing Cignal Reporter Assay firefly/renilla luciferase constructs (cat.# CCS-016L; Qiagen) with Attractene Transfection Reagent (Qiagen) in Opti-MEM supplemented with 1% MEM Non-essential amino acid solution without L-glutamine. After medium change test materials were added and their effect on RARE induction was quantified 24h later with the Dual-Luciferase Reporter Assay System (cat.# E1960; Promega).

[0248] Results and Discussion: RARE-mediated luciferase expression for each experimental condition measured in chemoluminescence units and as fold change vs. water control showed statistically-significant increase for all ATRA concentrations, which provided technical validation of the experiment. All test materials except Vit-A-Pal were active with Retinal being the best performer, followed by Near-1. As determined by the Renilla readings, none of the compounds were toxic at the tested concentrations. Overall, retinal is 1.7 times less effective than retinoic acid in modulating the RARE pathway at 1 uM, equivalent to retinoic acid at 5 uM. Table 32 presents the effect of test materials on RARE-mediated gene expression as % for all experimental conditions.

[0249] Example 12: Effect of 4 Test Materials on the Activation of Retinoic X Receptor transcription factor pathway.

[0250] Objective: Retinoid X receptors (RXRs) are one class of nuclear receptors through which retinoids mediate their biological effects. These receptors function as transcription factors by binding as heterodimers to specific sequences in the promoters of target genes. The protein encoded by this gene is a member of the steroid and thyroid hormone receptor superfamily of transcriptional regulators. One of its ligands is all trans retinoic acid (ATRA) - a compound with well-established anti-aging skin benefits. Despite these benefits ATRA also exhibits undesirable side effects, and the discovery of ATRA functional analogues with improved therapeutic and/or cosmetic activity profile is highly desirable. Cignal RXR Reporter Assay® is designed to screen for such compounds (retinoic acid (ATRA), retinal, 10%w/w Near-l in dimethylisosorbide, and 10%w/w retionoid ester in dimethylisosorbide) using cell cultures. The objective of this project was to test four compounds for the ability to activate RXR in this Cignal RXR Reporter Assay model.

[0251] The experiments were performed using HEK293 cells (Sigma, St. Louis, MO; cat.# 85120602) seeded at 50,000 per well in a 96 well black-wall tissue culture plate. Cells were transfected by mixing Cignal RXR Reporter Assay firefly/renilla luciferase constructs (cat.# CCS9044L; Qiagen) with Attractene Transfection Reagent (Qiagen) in Opti- MEM supplemented with 1% MEM Non-essential amino acid solution without Lglutamine. After medium change test materials were added and their effect on RXR induction was quantified 24h later with the Dual -Luciferase Reporter Assay System (cat.# El 960; Promega).

[0252] RXR is a mixture of an inducible retinoid X receptor - responsive firefly luciferase construct and a constitutively expressing Renilla construct, which acts as an internal control for normalizing transfection efficiencies and monitoring cell viability. Signal quantification was obtained with ThermoFisher Scientific Luminoskan Ascent Microplate Luminometer.

[0253] Results and Discussion: Results of RXR-mediated luciferase expression for each experimental condition measured in chemoluminescence units, as fold change vs. water control and as % of water control (Table 33) show statistically-significant increase for all ATRA concentrations, which provided technical validation of the experiment. All test materials except retinoid ester were active, with ATRA and Retinal being the best performers, followed by Near-1. As determined by the Renilla readings, none of the compounds were toxic at the tested concentrations.

[0254] Conclusion: NEAR-1 showed concentration dependent impact on RXR- mediated gene expression and at its highest tested concentration of lOuM it demonstrated statistically-significant modulatory effect (1.3 fold). Additionally, rretinal is 2.4 times less effective in modulating RXR pathway in comparison to retinoic acid at 5 uM.

Table 33: Effect of test materials on the RXR-mediated gene expression showed as % water control.

P values were calculated using two-tailed Student test. Bolded tests are experimental conditions having statistically-significant modulatory effect (>20% difference from water control and p<0.05).

[0255] Example 13 : Assessment of the Melanin-Modulatory Effect of Four Test Materials and of their Skin Irritation Potential in MelanoDermTM Skin Substitutes

[0256] Objective: The objective of this assay was to determine the ability of the test materials (dimethylisosorbide [DMI], retinoic acid [ATRA], 10%w/w NEAR-1 in dimethylisosorbide [NEAR-1], Niacinamide PC [NAD], and Kojic Acid [KA]) and combinations thereof to inhibit melanin production in MelanoDerm™ skin substitute model. The effect of these experimental conditions on the secretion of the proinflammatory cytokine IL-8 was also assessed, as a surrogate for skin irritation potential.

[0257] Tissues were equilibrated at 37°C for 60 min. and undiluted samples (25μ1) of test materials were applied on top of tissues in duplicates. DMI and kojic acid were applied at 2.5% and 2% (w:v) respectively (dissolved in double distilled water). Tissue culture was pursued in the pigmentation-inducing medium EPI-lOO- MM-1 13 for 14 days, with reapplication of test materials and changes of tissue culture media every 2-3 days.

[0258] At the end of the experiment, tissue pigmentation was quantified non- invasively with NS800 portable spectrophotometer (3 H Technology Co., Ltd., China). This instrument is a reflectance spectrophotometer that measures reflected light in the visible spectrum (range: 400-700nm) recording colors in a three-dimensional space known as CIEL*a*b* color space. In this project, the L* value representing the lightness of the color was used for color assessment. For the purpose of this experiment, the range of the L* parameter spanned from 17.8 (black background) to 87.8 (white background).

[0259] Tissue culture-conditioned media were assayed for the presence of IL-8 by indirect ELISA (using Invitrogen IL-8 Human CytoSet, cat.# CHC 1303).

[0260] For melanin quantification, the MelanoDerms were frozen, solubilized in Solvable™ (Perkin Elmer) and melanin was extracted at 95°C overnight. The colorimetric signals proportional to the concentration of extracted melanin, as well as those proportional to the IL-8 in the tissue-conditioned medium in the ELISA test were quantified with Molecular Devices microplate spectrophotometer MAX190 at 490nm and 405nm.

[0261] Results and Discussion: From the macroscopic documentation of all the MelanoDerm tissues at the end of the experiment, differences of color are clearly visible between the solvent controls and some test materials. Table 34 informs whether cytotoxicity may have played a role in these differences. Table 34 also reports the non-invasive MelanoDerm color measurement performed with portable spectrophotometer.

Table 34: Cytotoxicity, spectrophotometric color measurements and pigmentation of MelanoDerm tissues exposed to different experimental conditions for 2 weeks.

Cytotoxicity of test materials was determined by microscopic observation of MelanoDerm tissues. Non-invasive quantification of MelanoDerm pigmentation difference between test materials and solvent control was performed with portable spectrophotometer. Numbers represent the raw *L (brightness) values (higher the value - lighter the color). Pigmentation is expressed in μg/ml (melanin) and as % water control. N/A: not applicable.

[0262] At the end of the experiment, melanin extraction was initiated for selected tissues and completed two days later. Data analysis revealed decreased tissue pigmentation by the tested compounds, at least in part due to cytotoxicity (Table 34).

[0263] The quantification of interleukin 8 is reported in FIG. 16 and Table 35 shows a strong upregulation of this proinflammatory cytokine by all tested retinoid combinations.

Table 35: Actual numerical values corresponding to the IL-8 levels presented in FIG. 3.

Corresponding p values reflecting statistical significance of variance vs. water control col. units (colormetric units). [0264] Conclusion: In the retinoid category, NEAR-1 at 833μΜ and [Retinaldehyde 833 μΜ + NAD 835μΜ] combination appeared to provide the best whitening effect at non-cytotoxic concentration. Additionally, retinoic acid + niacinamide (both at 832 uM) lightened melanoderma 78% more than untreated control. In contrast, retinal + niacinamide (both at 832 uM) lightened the melanoderma 75% more versus untreated control, and was not cytotoxic. Note that niacinamide in this test was tested at 832 uM, is roughly 0.01%), which is 3 orders of magnitude (about 500 times) lower than its effective concentration for skin brightening effect, used topically in cosmetic formulation. Therefore, we consider its contribution to activity in this assay to be negligible.
