Two Phase 3, Randomized, Controlled Trials of Ruxolitinib Cream for Vitiligo.

BACKGROUND: Vitiligo is a chronic autoimmune disease that causes skin depigmentation. A cream formulation of ruxolitinib (an inhibitor of Janus kinase 1 and 2) resulted in repigmentation in a phase 2 trial involving adults with vitiligo. METHODS: We conducted two phase 3, double-blind, vehicle-controlled trials (Topical Ruxolitinib Evaluation in Vitiligo Study 1 [TRuE-V1] and 2 [TRuE-V2]) in North America and Europe that involved patients 12 years of age or older who had nonsegmental vitiligo with depigmentation covering 10% or less of total body-surface area. Patients were randomly assigned in a 2:1 ratio to apply 1.5% ruxolitinib cream or vehicle control twice daily for 24 weeks to all vitiligo areas on the face and body, after which all patients could apply 1.5% ruxolitinib cream through week 52. The primary end point was a decrease (improvement) of at least 75% from baseline in the facial Vitiligo Area Scoring Index (F-VASI; range, 0 to 3, with higher scores indicating a greater area of facial depigmentation), or F-VASI75 response, at week 24. There were five key secondary end points, including improved responses on the Vitiligo Noticeability Scale. RESULTS: A total of 674 patients were enrolled, 330 in TRuE-V1 and 344 in TRuE-V2. In TRuE-V1, the percentage of patients with an F-VASI75 response at week 24 was 29.8% in the ruxolitinib-cream group and 7.4% in the vehicle group (relative risk, 4.0; 95% confidence interval [CI], 1.9 to 8.4; P<0.001). In TRuE-V2, the percentages were 30.9% and 11.4%, respectively (relative risk, 2.7; 95% CI, 1.5 to 4.9; P<0.001). The results for key secondary end points showed superiority of ruxolitinib cream over vehicle control. Among patients who applied ruxolitinib cream throughout 52 weeks, adverse events occurred in 54.8% in TRuE-V1 and 62.3% in TRuE-V2; the most common adverse events were application-site acne (6.3% and 6.6%, respectively), nasopharyngitis (5.4% and 6.1%), and application-site pruritus (5.4% and 5.3%). CONCLUSIONS: In two phase 3 trials, application of ruxolitinib cream resulted in greater repigmentation of vitiligo lesions than vehicle control through 52 weeks, but it was associated with acne and pruritus at the application site. Larger and longer trials are required to determine the effect and safety of ruxolitinib cream in patients with vitiligo.

Phase 3 Trials of Tapinarof Cream for Plaque Psoriasis.

BACKGROUND: Tapinarof cream is a topical aryl hydrocarbon receptor-modulating agent under investigation for the treatment of psoriasis. Tapinarof modulates the expression of interleukin-17 and the skin-barrier proteins filaggrin and loricrin. METHODS: We conducted two identical phase 3 randomized trials of tapinarof in patients with mild-to-severe plaque psoriasis. Adults with a baseline Physician's Global Assessment (PGA) score of 2 (mild) to 4 (severe) (on a scale from 0 to 4, with higher scores indicating more severe psoriasis) and a percent of total body-surface area affected of 3 to 20% were randomly assigned in a 2:1 ratio to use tapinarof 1% cream or vehicle cream once daily for 12 weeks. The primary end point, PGA response, was a PGA score of 0 (clear) or 1 (almost clear) and a decrease from baseline of at least 2 points at week 12. Secondary efficacy end points at week 12 were a reduction of at least 75% in the Psoriasis Area and Severity Index (PASI) score, a PGA score of 0 or 1, the mean change from baseline in the percent of body-surface area affected, and a reduction of at least 90% in the PASI score. Patient-reported outcomes were the mean changes from baseline to week 12 in the proportion of patients who had a decrease of at least 4 points in the Peak Pruritus Numeric Rating Scale (PP-NRS) score (range, 0 [no itch] to 10 [worst imaginable itch]), the PP-NRS total score, the Dermatology Life Quality Index total score, and the Psoriasis Symptom Diary score. RESULTS: In trials 1 and 2, a total of 692 and 674 patients, respectively, were screened, with 510 and 515 patients being enrolled. A PGA response occurred in 35.4% of the patients in the tapinarof group and in 6.0% of those in the vehicle group in trial 1 and in 40.2% and 6.3%, respectively, in trial 2 (P<0.001 for both comparisons). Results for secondary end points and patient-reported outcomes were generally in the same direction as those for the primary end point. Adverse events with tapinarof cream included folliculitis, nasopharyngitis, contact dermatitis, headache, upper respiratory tract infection, and pruritus. CONCLUSIONS: Tapinarof 1% cream once daily was superior to vehicle control in reducing the severity of plaque psoriasis over a period of 12 weeks but was associated with local adverse events and headache. Larger and longer trials are needed to evaluate the efficacy and safety of tapinarof cream as compared with existing treatments for psoriasis.

Impact of Different Packaging Configurations on A Topical Cream Product.

PURPOSE: The objective of this study was to investigate whether different dispensing processes can alter the physicochemical and structural (Q3) attributes of a topical cream product, and potentially alter its performance. METHODS: Acyclovir cream, 5% (Zovirax®) is sold in the UK and other countries in a tube and a pump packaging configurations. The structural attributes of the cream dispensed from each packaging configuration were analyzed by optical microscopy, confocal Raman microscopy and cryo-scanning electron microscopy. Rheological behavior of the products was also evaluated. Product performance (rate and extent of skin delivery) was assessed by in vitro permeation tests (IVPT) using heat-separated human epidermis mounted in static vertical (Franz-type) diffusion cells. RESULTS: Differences in Q3 attributes and IVPT profiles were observed with creams dispensed from the two packaging configurations, even though the product inside each packaging appeared to be the same in Q3 attributes. Visible globules were recognized in the sample dispensed from the pump, identified as dimethicone globules by confocal Raman microscopy. Differences in rheological behaviour could be attributed to these globules as products not dispensed through the pump, demonstrated a similar rheological behaviour. Further, IVPT confirmed a reduced rate and extent to delivery across human epidermis from the product dispensed through a pump. CONCLUSIONS: Different methods of dispensing topical semisolid products can result in metamorphosis and Q3 changes that may have the potential to alter the bioavailability of an active ingredient. These findings have potential implications for product developers and regulators, related to the manufacturing and comparative testing of reference standard and prospective generic products dispensed from different packaging configurations.

Tapinarof cream 1% once daily: Significant efficacy in the treatment of moderate to severe atopic dermatitis in adults and children down to 2 years of age in the pivotal phase 3 ADORING trials.

BACKGROUND: Tapinarof cream 1% once daily (QD), a topical aryl hydrocarbon receptor agonist, downregulates pro-inflammatory Th2 cytokines, upregulates skin-barrier components, and reduces oxidative stress. OBJECTIVE: To assess tapinarof efficacy and safety in adults and children down to 2 years of age with atopic dermatitis (AD). METHODS: Eight hundred and thirteen patients were randomized to tapinarof or vehicle QD in two 8-week phase 3 trials. RESULTS: The primary efficacy endpoint, Validated Investigator Global Assessment for Atopic Dermatitis score of 0 or 1 and ≥2-grade improvement from baseline at Week 8, was met with statistical significance in both trials: 45.4% versus 13.9% and 46.4% versus 18.0% (tapinarof vs vehicle; both P < .0001). Significantly superior Eczema Area and Severity Index 75 (EASI75) responses were also observed with tapinarof versus vehicle at Week 8: 55.8% versus 22.9% and 59.1% versus 21.2% (both P < .0001). Rapid improvements in patient-reported pruritus were also significant with tapinarof versus vehicle. Common adverse events (≥5%) of folliculitis, headache, and nasopharyngitis were mostly mild or moderate, with lower discontinuations due to adverse events in the tapinarof groups than with vehicle. LIMITATIONS: Long-term efficacy was not assessed. CONCLUSION: Tapinarof demonstrated highly significant efficacy and favorable safety and tolerability in a diverse population of patients with AD down to 2 years of age.

Long-term safety and effectiveness of roflumilast cream 0.3% in adults with chronic plaque psoriasis: A 52-week, phase 2, open-label trial.

BACKGROUND: Efficacy and/or safety profiles limit topical psoriasis treatments. OBJECTIVE: Evaluate long-term effects of once-daily roflumilast cream 0.3% in patients with psoriasis. METHODS: In this open-label phase 2 trial, adult patients (N = 332) with psoriasis who completed the phase 2b parent trial or were newly enrolled applied roflumilast once-daily for 52 weeks. Safety and effectiveness were assessed. RESULTS: Overall, 244 patients (73.5%) completed the trial; 13 patients (3.9%) discontinued due to adverse events (AEs) and 3 (0.9%) due to lack of efficacy. Twelve patients (3.6%) reported treatment-related AEs; none were serious. ≥97% of patients had no irritation. No tachyphylaxis was observed with 44.8% of the patients achieving Investigator Global Assessment (IGA) Clear or Almost Clear at Week 52. LIMITATIONS: Intertriginous-IGA and Psoriasis Area and Severity Index (PASI) were not evaluated in all patients. CONCLUSIONS: In this long-term trial, once-daily roflumilast cream was well-tolerated and efficacious up to 64 weeks in patients in the earlier trial, suggesting it is suitable for chronic treatment, including the face and intertriginous areas.

Topical nanoencapsulated cannabidiol cream as an innovative strategy combating UV-A-induced nuclear and mitochondrial DNA injury: A pilot randomized clinical study.

BACKGROUND: UV-A radiation contributes to photoaging/photocarcinogenesis by generating inflammation and oxidative damage. Current photoprotective strategies are limited by the availability/utilization of UV-A filters, highlighting an unmet need. Cannabidiol (CBD), having anti-inflammatory/antioxidant properties via regulation of nuclear erythroid 2-related factor, heme oxygenase 1, and peroxisome proliferator-activated receptor gamma, could potentially mitigate damage from UV-A exposure. OBJECTIVE/METHODS: This is a prospective, single-center, pilot clinical trial (NCT05279495). Nineteen participants applied nano-CBD (nCBD) or vehicle (VC) cream to randomized, blinded buttock sites twice daily for 14 days; then, the treated sites were irradiated with ≤3× UV-A minimal erythema dose. After 24 hours, punch biopsies were obtained for histology, immunohistochemistry, and real-time polymerase chain reaction. RESULTS: At 24 hours, 21% of participants had less observed erythema on CBD-treated skin than on VC skin. Histologically, nCBD-treated skin had reduced UV-A-induced epidermal hyperplasia than VC (P = .01). Immunohistochemistry detected reduced cytoplasmic/nuclear 8-oxoguanine glycosylase 1 staining in nCBD-treated skin compared with VC (P < .01). Quantitative mtDNA polymerase chain reaction demonstrated that UV-A-induced deletion of ND4 (proxy:4977 bp deletion; P = .003) and ND1 (proxy:3895 bp deletion; P = .002) was significantly reduced by in vivo nCBD treatment compared with VC. LIMITATIONS: Small sample size is this study's limitation. CONCLUSION: Topically applied nCBD cream reduced UV-A-induced formation of a frequent mutagenic nuclear DNA base lesion and protected against mtDNA mutations associated with UV-A-induced skin aging. To our knowledge, this trial is the first to identify UV-protective capacity of CBD-containing topicals in humans.

Parent satisfaction with lotion, cream, gel and ointment emollient types: secondary analysis of the Best Emollients for Eczema study.

BACKGROUND: The main determinant of emollient effectiveness is whether it is used, which in turn is linked with user satisfaction. OBJECTIVES: To compare parental satisfaction with emollient type for the treatment of childhood eczema. METHODS: Secondary analysis of data from the Best Emollients for Eczema (BEE) trial was undertaken. In total, 550 children aged between 6 months and 12 years were recruited from primary care in England and randomized to use a lotion, cream, gel or ointment as their main emollient for 16 weeks. At week, 16 parents were asked to complete an Emollient Satisfaction Questionnaire (ESQ). Completion rates and scores were compared, using χ2 test, t-test calculations and one-way Anova as appropriate. RESULTS: Data on 378 participants (68.7% of those randomized) were analysed. Mean ESQ scores were gel 20.9 (SD 5.3), lotion 20.4 (SD 5.6), cream 18.8 (SD 6.3) and ointment 15.2 (SD 6.8) (P < 0.001). In pairwise comparisons, there was a statistically significant difference in mean ESQ scores between ointment and lotion (P < 0.001), ointment and cream (P < 0.001) and ointment and gel (P < 0.001) but not between lotion, cream and gel. Participants using lotions had highest overall satisfaction and were most likely to continue using their emollient. ESQ scores were correlated with reported emollient use and improvements in parent-reported eczema severity. CONCLUSIONS: Overall, lotions and gels were favoured over creams and ointments. Although satisfaction is determined by personal preference, these results will aid parents, clinicians and children to find the right emollient(s) for them.

Randomised, split-face study of a dermocosmetic cream containing Sphingobioma xenophaga extract and Neurosensine® in subjects with rosacea associated with erythema and sensitive skin.

INTRODUCTION: Rosacea is a chronic inflammatory skin condition associated with erythema, inflammation and skin sensitivity. OBJECTIVES: To assess the benefit of a dermocosmetic cream (DC cream) containing Sphingobioma xenophaga extract and soothing agent in adult females with rosacea-associated erythema and sensitive skin. MATERIALS AND METHODS: During phase 1, DC was applied twice daily on the randomized half-face and compared to usual-skincare (USC) for 28 days. During phase 2, DC was applied on the full face twice daily for 56 days. Clinical, instrumental and skin sensitivity assessments were performed at all visits; demodex density (standardized skin surface biopsy (SSSB) method) was performed at baseline and D28, quality of life (QoL) was assessed using the stigmatization questionnaire (SQ), Rosacea Quality of Life index (ROSAQoL) and Dermatology Life Quality Index (DLQI) at baseline and D84. RESULTS: At D28, a significant benefit of DC over USC was observed for erythema, tightness, burning and stinging (all p ≤ 0.05), erythema measured by chromameter (p < 0.01), corneometry and transepidermal water loss (p < 0.0001 and p < 0.05, respectively), skin sensitivity (p < 0.001) and significant reduction of mean demodex density (p < 0.05) on the DC side. At D84, DC significantly (all p < 0.05) improved clinical signs and symptoms on both sides of the face compared to baseline; SQ, ROSAQoL and DLQI scores improved by 40.4%, 25.0% and 55.7%, respectively compared to baseline. Tolerance was excellent. CONCLUSION: DC significantly improved erythema, skin sensitivity, demodex count, QoL and feeling of stigmatization of subjects with rosacea and is very well tolerated.

Establishment and application of perceived age prediction model for the periocular aging research of Chinese Han women.

BACKGROUND: The assessment of skin aging through skin measurements faces limitations, making perceived age evaluation a more valuable and direct tool for assessing skin aging. Given that the aging process markedly affects the appearance of the eye contour, characterizing the eye region could be beneficial for perceived age assessment. This study aimed to analyze age-correlated changes in the eye contour within the Chinese Han female population and to develop, validate, and apply a multiple linear regression model for predicting perceived age. MATERIALS AND METHODS: A naïve panel of 107 Chinese women assessed the perceived ages of 212 Chinese Han women. Instrumental analysis evaluated periorbital parameters, including palpebral fissure width (PFW), palpebral fissure height (PFH), acclivity of palpebral fissure (AX), angle of inner canthal (AEN), and angle of outer canthal (AEX). These parameters were used to construct a multiple linear regression model for predicting the perceived ages of Chinese Han women. A combined treatment using Fotona 4D and an anti-aging eye cream, formulated with plant extracts, peptides, and antioxidants, was conducted to verify the cream's anti-aging efficacy and safety. This eye cream was then tested in a large-scale clinical trial involving 101 participants. The prediction model was employed in this trial to assess the perceived ages of the women after an 8-week application of the eye cream. RESULTS: All parameters were observed to decrease with age. An intergroup comparison indicated that eyelid aging in Chinese Han women accelerates beyond the age of 50. Consequently, a linear regression model was constructed and validated, with the perceived age being calculated as 183.159 - 1.078 * AEN - 4.487 * PFW + 6.061 * PFH - 1.003 * AX - 0.328 * AEX. The anti-aging efficacy and safety of the eye cream were confirmed through combined treatment with Fotona 4D, showing improvements in wrinkles, elasticity, and dark circles under the eyes. In a large-scale clinical evaluation using this eye cream, a perceived age prediction model was applied, suggesting that 8 weeks of use made participants appear 2.25 years younger. CONCLUSION: Our study developed and validated a multiple linear regression model to predict the perceived age of Chinese Han women. This model was successfully utilized in a large-scale clinical evaluation of anti-aging eye cream, revealing that 8 weeks of usage made participants appear 2.25 years younger. This method effectively bridges the gap between clinical research and consumer perceptions, explores the complex factors influencing perceived age, and aims to improve anti-aging formulations.

Comprehensive evaluation of the efficacy and safety of a new multi-component anti-aging topical eye cream.

BACKGROUND: The delicate periorbital region is susceptible to skin dehydration, wrinkles, and loss of elasticity. Thus, targeted and effective anti-aging interventions are necessary for the periorbital area. AIM: To evaluate the efficacy and safety of a new anti-aging eye cream formulated with the active complex (Yeast/rice fermentation filtrate, N-acetylneuraminic acid, palmityl tripeptide-1, and palmitoyl tetrapeptide-7). METHODS: The cell viability and expressions of key extracellular matrix (ECM) components of the active complex were evaluated using a human skin fibroblast model. In the 12-week clinical trial, skin hydration, elasticity, facial photographs, and collagen density following eye cream application were assessed using Corneometer, Cutometer, VISIA, and ultrasound device, respectively. Dermatologists and participants evaluated clinical efficacy and safety at baseline, and after 4, 8, and 12 weeks. RESULTS: PCR and immunofluorescent analyses revealed that the active complex significantly stimulated fibroblast proliferation (p < 0.05) and markedly promote the synthesis of collagen and elastin. Clinical findings exhibited a substantial enhancement in skin hydration (28.12%), elasticity (18.81%), and collagen production (54.99%) following 12 weeks of eye cream application. Dermatological evaluations and participants' assessments reported a significant improvement in skin moisture, roughness, elasticity, as well as fine lines and wrinkles by week 8. CONCLUSION: The new anti-aging eye cream, enriched with the active complex, demonstrates comprehensive rejuvenating effects, effectively addressing aging concerns in the periorbital area, coupled with a high safety profile.

Treatment of Granuloma Annulare Using Tapinarof Cream 1.

Granuloma annulare is a benign, non-infectious cutaneous granulomatous disease. Its pathogenesis is not completely elucidated but has recently been thought to involve immunologic and cytokine receptor signaling dysregulation. This includes the involvement of both Th1 and Th2 pathways as well as Th17 and Th22 axes and the Janus kinase/signal transducers and activators of the transcription (JAK-STAT) pathway. First-line treatment is typically intralesional or topical corticosteroids, however, these therapies do not always provide consistent, long-term efficacy for all patients. The successful use of therapies that target the specific inflammatory and immunologic mechanisms that underlie the pathogenesis of GA has been described. Here we describe a case of long-standing GA treated with tapinarof cream 1% applied once daily for 30 days. To our knowledge, this treatment has not yet been adequately described in the literature. J Drugs Dermatol. 2024;23(10):889-893.  doi:10.36849/JDD.8321.

Image Analysis of Xerosis and Atopic Dermatitis Following Prebiotic Skincare Regimen in Ethnically Diverse Patients.

Variations in the epidemiology, clinical presentation, and disease course in atopic dermatitis (AD) patients with Skin of Color (SOC) compared with white counterparts have been reported. In this study, we evaluated the capability of a new imaging device (SkinCam) in quantifying skin texture changes in diverse patients, presenting with AD or xerosis, after using a prebiotic skincare routine over 10 weeks.  A total of 39 subjects from diverse racial/ethnic backgrounds, aged 3 to 76 years old, with Fitzpatrick skin phototypes I to VI, presenting with mild AD and moderate to severe xerosis, were enrolled in the study. All subjects used a prebiotic cleanser on its own for 2 weeks, followed by a prebiotic moisturizer in conjunction for an additional 8 weeks. Standardized images of the subjects' legs were taken with SkinCam at several time points (baseline, week 2, and week 10), and analyzed for skin texture parameters. Our results demonstrate that both skin texture irregularity and skin color patterns significantly improve over time with a prebiotic skincare regimen in AD (n=12) and xerosis (n=24) subjects. Interestingly, image analyses showed more improvement over time in xerosis and AD SOC patients (n=18, Fitzpatrick IV-VI). Lastly, skin texture analyses from SkinCam imaging correlated with clinical assessments, showing significant improvement by prebiotic skincare regimen in all subjects by week 10. In summary, our results demonstrate that the SkinCam imaging device has the capability to effectively monitor skin texture parameters over time in both AD and xerosis patients with lightly and darkly pigmented skin. J Drugs Dermatol. 2024;23(7):557-563.  doi:10.36849/JDD.8371.

Ruxolitinib 1.5% Topical Cream for the Treatment of Pediatric Alopecia Areata.

Alopecia areata (AA) is a common autoimmune disorder. Although its pathogenesis is not fully understood, AA involves CD8 T cell-mediated destruction of the hair follicle. Several treatment options exist; however, there is minimal evidence in the pediatric population. Currently, there are no curative treatments for AA. The literature suggests that Janus kinase (JAK) inhibitors may be an effective treat-ment for AA, but evidence in pediatric patients is limited. Here, we report a case of severe pediatric AA treated with topical ruxolitinib, a JAK inhibitor. J Drugs Dermatol. 2024;23(5):378-379. doi:10.36849/JDD.7782.

Going Beyond Ceramides in Moisturizers: The Role of Natural Moisturizing Factors.

Xerosis is experienced by almost everyone at some time in their lives and the foundation of management of dry skin (both consumer- and healthcare professional--directed) rests on the use of moisturizers. Given the wide range of available moisturizers, counseling patients about selecting the optimum moisturizer for their individual situation relies on knowledge of ingredients and formulations. Traditionally, the main focus for many moisturizers centered on the core functional and structural role of ceramides within the epidermal barrier.  However, while a key aspect of transepidermal water loss and other skin barrier functions, components other than ceramides are equally essential in increasing moisturization. The skin's natural moisturizing factors (NMFs) are a complex mixture of water-attracting compounds such as amino acids, urea, lactate, pyrrolidone carboxylic acid (PCA), and electrolytes which play a fundamental role in preserving physiologic function by regulating the water content of the stratum corneum. By facilitating water retention, NMFs contribute significantly to the suppleness, elasticity, normal desquamation, and overall integrity of the skin barrier. Incorporation of NMFs into moisturizers addresses critical deficiencies in the skin's moisture balance that exist in xerotic and atopic skin, and in many skin disorders, mitigating signs and symptoms associated with xerosis and promoting optimal skin health. The biochemical composition of NMFs and the intricate interplay with epidermal homeostasis translate to a central role in moisturizers used for prophylactic and therapeutic management of various dry skin conditions, beyond ceramides alone.

Heatmap Evaluation of Facial Hydration Using a Novel Python Program.

BACKGROUND: Evaluating cleansers and moisturizers provides important information to guide clinicians in the recommendation of these products. This project was performed to visualize skin hydration via heatmap after the use of a gentle skin cleanser (GSC) and moisturizing lotion (ML). METHODS: Half-face, intra-individual open-label study in healthy volunteers. Cleanser was administered in a single application that was then wiped off the face. Moisturizing lotion was applied at least once-daily for one week. Hydration measurements were made at 30 pre-defined points on half of the face, at baseline, and 30 minutes post-application; an additional assessment at week 1 was made for the moisturizing lotion. Heatmaps were generated using Python programming software to interpolate hydration values to colors that were then superimposed onto the volunteer's facial image.  Results: Five subjects completed the cleanser assessments, and 5 subjects completed the 30-minute evaluation for the lotion, with 4 completing the week 1 assessment. There was a visible shift in skin hydration post-GSC application from values approximately in the 12-42 AU (arbitrary unit) range to 30-60 AU at 30 minutes. Similarly, there was a shift in hydration from baseline to 30 minutes that continued to increase through week 1 of ML use. CONCLUSIONS: This innovative heatmap data generation showed a clear, visual change in hydration over time. There was a visible shift in hydration values from baseline to 30 minutes after application of cleanser; hydration also improved after use of moisturizing lotion at 30 minutes and increased after week 1 application.  J Drugs Dermatol. 2024;23(6):463-465.     doi:10.36849/JDD.8221.

Effects of a Sheer 100% Mineral Sunscreen Moisturizer on Facial Photodamage Across Fitzpatrick Skin Types.

BACKGROUND: All skin tones need to be protected from the damaging effects of solar radiation. Although mineral sunscreens offer protection, they can have a thick, greasy feel and leave a white cast, particularly on darker skin tones. Tints offset white cast and provide visible light protection; however, patients may prefer a sheer option. Therefore, a multifunctional, sheer, 100% mineral sunscreen moisturizer (MSM) with broad-spectrum SPF 50 was developed to have positive aesthetics and deliver anti-aging and skin health benefits to all skin tones.  Methods: An IRB-approved, 12-week, open-label clinical study was conducted to investigate the efficacy and tolerability of the MSM. Thirty-nine (39) females aged 35 to 60 years with moderate-severe overall facial photodamage and representing all Fitzpatrick skin types (FST) were recruited. Participants applied the MSM to the face and neck in the morning and reapplied per US Food and Drug Administration requirements. Efficacy and tolerability grading, photography, ultrasound imaging, corneometer measurements, and questionnaires were completed at baseline and weeks 4, 8, and 12.  Results: Statistically significant progressive improvements were demonstrated from baseline to week 12. At week 12, 23.4% and 26.5% mean improvements in overall photodamage were seen for FST I-III and FST IV-VI, respectively. Favorable tolerability was shown for both the face and neck. Photography corroborated clinical grading, and ultrasound imaging indicated a trend in skin density improvement. The MSM was well-perceived.  Conclusion: The MSM is an efficacious and well-tolerated product for patients of all skin tones who desire a sheer, 100% mineral sunscreen moisturizer with anti-aging and skin health benefits. J Drugs Dermatol. 2024;23(7):538-544.  doi:10.36849/JDD.8082.

Topical Steroids Sold as Fade Creams in Beauty Supply Stores: A Danger for Cosmetic Consumers.

Topical corticosteroids are used extensively in dermatology. Class 1 high potency topical steroids (HPTS) can result in unwanted side effects such as skin hypopigmentation, atrophy, and acneiform eruptions. HPTS are only legally available by prescription to ensure appropriate use in the United States (US). The authors have noticed a recent increase in patients presenting with steroid acne after buying HPTS products in beauty supply stores. These products are marketed as fade creams to treat hyperpigmentation and uneven skin tone. We assessed skincare products containing HPTS (clobetasol or betamethasone) in 33 beauty supply stores in Miami, FL; Washington, DC; and Baltimore, MD. Out of 33 beauty supply stores, 14 (42.42%) contained HPTS skincare products, and they were all located in Miami. Out of 15 stores visited in Miami, 14 (93.33%) contained skincare products with clobetasol, and 5 (33.33%) contained skincare products with both clobetasol and betamethasone. Of the stores selling HPTS skincare products, the number of different brands available ranged from 1 to 7, with an average of 4.21 different brands per store. Our study reveals that HPTS are readily available in over-the-counter skincare products in many beauty supply stores. HPTS skincare products were only available in one of three cities suggesting there may be a regional supplier distributing these products. It may also indicate that there is less oversight of retail stores in Miami with HPTS products. More studies are needed to quantify the availability of these products in different locations throughout the US. Further Studies can help identify this problem and raise awareness among consumers of the dangers of HPTS skincare products in beauty supply stores.

Efficacy, Safety, Satisfaction, Adherence to Treatment With Nano-Formulated Cysteamine Tranexamic Acid Cream to Treat Melasma.

BACKGROUND: Melasma is a chronic pigmentary disorder. In this study, an innovative cream combining cysteamine and tranexamic acid (TXA) was assessed. OBJECTIVE: To evaluate the safety, efficacy, and patient satisfaction of a novel nano-formulated cysteamine and TXA combination cream in treating subjects with epidermal melasma. METHODS:   Fifty (50) randomized subjects participated and received cysteamine and TXA combination cream. The cream was applied for 30 minutes daily for a 3-month duration. Treatment effectiveness, safety, patient satisfaction, and adherence were evaluated. RESULTS: A continuous improvement in melasma was observed, with modified Melasma Area and Severity Index (mMASI) scores improving by 40%, 57%, and 63% at 30, 60, and 90 days, respectively. The primary endpoint of a decrease in mMASI scores was met, with 91% of participants experiencing melasma improvement. Patient Satisfaction and Patient Adherence scores indicated satisfaction. Convenience exhibited the strongest correlation with patient adherence.  Conclusion: Nano-formulated cysteamine and TXA combination cream showed significant efficacy in decreasing mMASI score while demonstrating a strong safety profile and patient satisfaction.  J Drugs Dermatol. 2024;23(7):529-537.     doi:10.36849/JDD.7765R1.

Assessment of the Vehicle for Roflumilast Cream Compared to a Ceramide-Containing Moisturizing Cream in Mild Eczema.

BACKGROUND: Inflammatory dermatologic conditions suitable for topical treatments benefit from a hydrating vehicle that improves the skin barrier without irritation. OBJECTIVE: This research was designed to assess skin barrier effects and aesthetic attributes of the vehicle for topical roflumilast cream (vehicle) vs a currently marketed ceramide-containing moisturizing cream (moisturizer). METHODS: This was a single-site, randomized, intraindividual, double-blind, controlled study conducted over 17 days. Patients (aged 18 years or older) with mild, symmetric asteatotic eczema of the lower extremities were enrolled to receive lower leg applications of the vehicle on one leg and moisturizer on the other. The primary efficacy endpoint was a change in transepidermal water loss (TEWL) from baseline to day 15. Secondary efficacy endpoints included change from baseline in TEWL at other study visits, change from baseline in hydration as assessed via corneometry, and patient- and investigator-rated assessments of the products. Safety and tolerability were also assessed. RESULTS: A total of 40 patients enrolled in the study. The primary efficacy endpoint was met for both treatments. A statistically significant difference in TEWL on day 1 favored the moisturizer, but no difference was seen between vehicle and moisturizer at any other timepoint. Both vehicle and moisturizer also met the secondary efficacy endpoint of change from baseline in hydration. LIMITATIONS: The sample size was small. CONCLUSIONS: The vehicle for roflumilast cream performed similarly to a leading, currently marketed, dermatologist-recommended, ceramide-containing moisturizer across all patient- and investigator-rated assessments of efficacy, tolerability, and aesthetic properties in patients with mild asteatotic eczema.

Photo Visualization of Skintone Compatibility of an SPF 35 Sunscreen.

BACKGROUND: Visual casts and discoloration are common barriers to sunscreen use in melanin-rich populations. However, photoprotective measures are essential for individuals with all skin types, including darker skin. METHODS: Single-center, 7-day, open-label study of healthy adult females with Fitzpatrick Skin Types (FST) IV to VI and sensitive skin treated with once-daily daily facial moisturizer sun protection factor 35 (DFM SPF35). Subjects completed a cosmetic acceptability questionnaire at days 1 and 7. Photography using VISIA CR was performed at day 7. Adverse events were monitored throughout the study. RESULTS: Thirty-two (32) subjects participated; 31.3% had FST IV, 53.1% V, and 15.6% VI skin. DFM SPF35 was viewed as cosmetically elegant. At day 1, 96.7% of subjects agreed product was easy to apply; 90.0% reported soft skin after product use; 86.7% said it had a lightweight, non-greasy feel and hydrated the skin. At day 7, 93.7% reported no visible white residue on their skin and said the product applied easily/absorbed well. The majority (90.6%) would continue using and would recommend the product; and 87.5% reported the product blended seamlessly into their skin, which agreed with clinical photography. Responses were consistent among subjects with normal, oily, or combination skin. No adverse events were reported. CONCLUSIONS: DFM SPF35 blended well into the skin and was perceived favorably among subjects with SOC after 1 and 7 days of use. Subjects felt it had good cosmetic acceptability without unacceptable white residues or a greasy feeling. Dermatologists need to be versed in products that can be used on a variety of skin types.J Drugs Dermatol. 2024;23(7):515-518.  doi:10.36849/JDD.8223.
