RESUMO

Skin aging is influenced by various exogenous and endogenous factors, ranging from ultraviolet (UV) light exposure and environmental toxins to biological sources, such as those that arise from normal metabolic processes (eg, free radicals). Glycation is the normal process by which glucose and other reducing sugars react with proteins to form an array of heterogeneous biomolecular structures known as advanced glycation end-products (AGEs) over time. However, AGEs are toxic to human cells and are implicated in the acceleration of inflammatory and oxidative processes, with their accumulation in the skin being associated with increased skin dulling and yellowing, fine lines, wrinkles, and skin laxity. Clinicians should become cognizant of how AGEs develop, what their biological consequences are, and familiarize themselves with available strategies to mitigate their formation.

RESUMO

Atopic Dermatitis (AD) epidemiologic studies report a higher incidence and prevalence among populations with skin of color (SOC). Additionally, differences in AD underlying gene mutations and skin morphology are observed to lead to frequent and prominent xerosis, pruritus, and pigmentary sequelae in patients of color. However, populations with SOC are underrepresented in dermatology clinical trials, including AD. This article reviews the nuances in AD epidemiology, clinical presentation, and impact on quality-of-life among populations with SOC, plus highlight the role of skincare in AD management.

RESUMO

Atopic Dermatitis (AD) is a chronic relapsing inflammatory skin disease associated with a significant patient burden on quality-of-life. Given skin barrier including skin microbiome changes are linked to AD pathogenesis, prebiotic emollients are shown to improve disease symptoms and maintain skin barrier integrity, normalizing skin microbiota. In this study, we evaluated the efficacy and safety of a prebiotic skincare routine in improving AD and xerosis, and ultimately quality-of-life in ethnically diverse patients. A total of 140 subjects from different racial/ethnic backgrounds, aged 3-80 years old with skin phototypes I-VI, and presenting with mild-AD or severe xerosis completed study. Expert grading, instrumentation, self-assessment questionnaires, plus clinical imaging demonstrated that a prebiotic cleanser and moisturizer routine significantly reduced skin conditions severity, strengthened skin barrier properties in both lesional and normal skin, and improved patients' quality-of-life while providing itch relief as soon as 4 weeks. The results of this research indicate that a prebiotic cleanser and moisturizer regimen offers benefits for diverse patient’s daily skincare routine by effectively managing AD and xerosis severity and symptoms, normalizing skin microbiota, plus preserving skin barrier integrity to prevent long-term sequelae.

RESUMO

Objective: The ability of the skin to maintain homeostasis declines with age. Adaptogens support the capacity of the skin to respond to stress. We sought to evaluate the efficacy of a novel serum comprised of plant-based adaptogens for improving photoaged skin following twice-daily application. Methods: A multi-center, 12-week trial was conducted in participants aged 45 to 65 years, Fitzpatrick Skin Type (FST) I to VI, with mild-to-severe photoaging based on a 10-point grading scale (3 [Minimum] to 7 [Maximum]). Visible improvements were assessed in erythema, pore size, skin dullness, skin texture, and uneven pigmentation utilizing a six-point grading scale (0=None to 5=Severe). Global skin quality was measured utilizing our Global Skin Quality Index (GSQI). Sebum measurements were obtained in a subset of participants. Patient satisfaction and tolerability were recorded throughout the study. Results: Fifty-three participants were enrolled and completed the study. Mean age was 56 years and 66 percent were White, 17 percent were Black, 8 percent were Hispanic, 6 percent were Asian/Pacific Islander, and 81 percent had moderate photodamage. At Week 12, significant mean percent improvements from baseline were demonstrated in erythema (50%), dullness (44%), texture (52%), pore size (23%), and uneven pigmentation (21%; all p<.0001). Significant GSQI improvements from baseline were observed at Week 12 (39%; p<0.0001). Significant mean reductions from baseline in skin surface sebum were demonstrated at Week 12 (-38%; p<0.0001). All adverse events (AEs) were mild and transient. Conclusion: A novel serum comprised of plant-based adaptogens, demonstrated improvements from baseline in the appearance of erythema, dullness, texture, pore size, uneven pigmentation, and global skin quality over 12 weeks. Participants reported high levels of satisfaction, with mild, transient AEs reported.

RESUMO

Objective: A topical serum comprised of plant-based adaptogens was purposefully developed to support the ability of the skin to adapt and achieve balance. The study described herein evaluated changes in the expression of target genes related to skin homeostasis following topical exposure. Methods: Utilizing an in vitro epidermal skin model, quantitative polymerase chain reaction (qPCR) analysis of gene expression was conducted following 48-hour exposure to 15µL of the study product (MYS serum) to the surface of each tissue (N=4). Biomarkers that play a key role in skin homeostasis were analyzed: Aryl hydrocarbon receptor (AhR), chloride channel accessory 2 (CLCA2), metallothionein 1A (MT1A), 1F (MT1F), and 1G (MT1G), and thioredoxin reductase 1 (TXNRD1). Statistically significant changes were calculated using unpaired t-test analysis (p<0.05) versus control (saline). A linear Fold Change (FC) value >2 was considered statistically significant. Results: An 85 percent (FC=1.85) increase in expression of AhR vs. control occurred following exposure to MYS serum indicating enhanced support of cellular and epidermal homeostasis, and the skin barrier's response to stress. Statistically significant increases in expression occurred with TXNRD1 (293%; FC=3.93), MT1A (307%; FC=4.07), MT1F (529%; FC=6.29), and MT1G (163%; FC=12.63) vs. control, indicating support of skin's adaptive response to stress and immune homeostasis. Significantly decreased levels of CLCA2 were demonstrated (69%; FC=-3.24) indicating inhibition of oxidative stress-induced senescence. Conclusion: Utilizing an in vitro epidermal skin model, a serum comprised of plant-based adaptogens demonstrated changes in the expression of target genes that play important roles in skin's ability to respond to stress and achieve homeostasis.

RESUMO

INTRODUCTION: Facial aging is a multifactorial phenomenon due to poor skin hydration, deficient intercellular communication, collagen/elastin breakdown, and oxidative stress. The objective of this study was to assess the efficacy of a multimechanistic antiaging prototype formulation on the appearance of photoaged facial skin after 24 weeks of twice daily use. METHODS: Fifty female subjects 35-65 years of age of all Fitzpatrick skin types with mild to moderate facial photoaging concerns (fine lines, wrinkles, sagging skin, tone and texture) were enrolled in this monadic study. Investigator and subject tolerability assessments were performed along with facial noninvasive corneometry hydration and elasticity measurements. The dermatologist investigator assessed fine lines, wrinkles, skin evenness, radiance, plumping, texture/smoothness, sagging/firming/lifting, and global appearance on a 5-point ordinal scale. RESULTS: Forty-seven of the 50 subjects completed the study with a 19% increase in skin firmness and a 35% increase in skin hydration via bio-instrumentation readings after 24 weeks of study product use. The investigator assessed a 40% improvement in lines, a 23% improvement in wrinkles, a 42% improvement in evenness, a 64% improvement in radiance, a 58% improvement in plumping, a 65% improvement in texture, a 60% improvement in firmness, and a 45% improvement in overall appearance at 24 weeks. CONCLUSION: The serum combination of humectants, peptides, and antioxidants yielded excellent tolerability with visual and mechanistic skin improvement beginning at 1 week with cumulative continuing improvement through 24 weeks of use in terms of hydration, firmness, texture, radiance, and fine lines.

RESUMO

OBJECTIVE: Fixed-combination halobetasol propionate (0.01%) and tazarotene (0.045%) lotion (HP/TAZ) is approved for the treatment of plaque psoriasis in adults, with a demonstrated efficacy and safety profile in phase 3 trials. This study examined the effect of HP/TAZ on the reduction of tumor necrosis factor alpha (TNF-α) and interleukin 17 A (IL-17A) and its correlation to psoriasis improvement. MATERIALS AND METHODS: Ten adults with mild-to-moderate plaque psoriasis and 2 symmetrical plaques self-applied HP/TAZ (treated plaque) or vehicle lotion (untreated plaque) for 12 weeks. At baseline and each study visit (weeks 2, 4, 8, and 12), Investigator's Global Assessment (IGA) score and erythema, scaling, and induration were assessed. Additionally, D-squame tape strips were utilized to quantify TNF-α and IL-17A in target lesions by enzyme-linked immunosorbent assay. RESULTS: Significant improvements in mean IGA score in HP/TAZ-treated compared with untreated plaques were evident at week 2 and maintained through week 12 (p < 0.003). HP/TAZ significantly reduced TNF-α levels at weeks 4 through 12 (p < 0.03) and IL-17A levels at weeks 2 through 8 (p < 0.05) in treated compared with untreated plaques. CONCLUSIONS: HP/TAZ was highly effective in treating psoriasis plaques and, although HP/TAZ is not a biologic, effectively reduced cytokine-associated inflammatory markers that drive psoriatic disease.

RESUMO

Barrier damage caused by facial acne vulgaris can be magnified by topical medication, such as adapalene (0.3%) and benzoyl peroxide (2.5%)(A/BPO), which utilizes a retinoid to normalize follicular keratinization and BPO to decrease the C. acnes population. Disease-induced irritation combined with topical medication-induced irritation results in dryness and enhanced inflammation leading to lower compliance and increased skin healing time. Ceramide-based moisturizers have documented barrier repair benefits for eczema but have not been studied for acne. The objective of this double-blind study was to measure the impact of acne treatment on skin barrier function and tolerance when paired with a ceramide routine. Participants were prescribed an A/BPO gel once daily. The treatment group received a ceramide-containing foaming facial cleanser and facial lotion, and the control group received basic foaming face wash for twice-daily use. Participant and investigator tolerability and efficacy were evaluated by both ordinal and clinical measures. Acne lesion counts and Investigator’s Global Assessments (IGA) of acne were obtained along with transepidermal water loss (TEWL) measurements for barrier function. TEWL for the treatment group remained significantly lower than the control at all timepoints and significantly improved from baseline by week 12. The treatment group had statistically lower mean investigator scores for dryness at all timepoints. Inflammatory lesion counts were significantly lower for the treatment group. A/BPO damaged the skin barrier, demonstrated by elevated TEWL, contributing to dryness, redness, and scaling. Use of a ceramide-containing cleanser and moisturizer significantly reduced severity and incidence of dryness, erythema, and scaling while more quickly resolving barrier damage and restoring function.

RESUMO

INTRODUCTION: Effective topical drug delivery is the essence of dermatologic treatment. The drug must be applied to the skin surface, be released from the vehicle, enter the stratum corneum, traverse the epidermis, and enter the dermis pharmacologically intact. New advances have improved emulsion-type formulation and drug delivery technology by encapsulating dispersed oil droplets in a robust multimolecular aqueous film of surfactants, oil, and water, enabling a multifold decrease in surfactant concentration compared to conventional creams. In the research reported here, we studied this new concept, termed polyaphron dispersion (PAD) technology, by comparing skin delivery of betamethasone dipropionate from a novel oil-in-water emulsion system of calcipotriene and betamethasone dipropionate (CAL/BDP) cream to that from a traditional topical suspension (CAL/BDP TS) utilizing in vitro and in vivo detection methods. METHODS: The amount of BDP released from the CAL/BDP cream and CAL/BDP TS was evaluated using both in vitro Franz cell analysis and in vivo human tape stripping from ten female human volunteers after a single application of CAL/BDP cream or CAL/BDP TS. For the tape stripping analysis, 20 circular tape strips were taken from forearm application sites at 1, 2, 4, and 8 h after application and analyzed for the amount of BDP in the tape strip using liquid chromatography-mass spectrometry (LC-MS). RESULTS: The in vitro Franz cell analysis demonstrated that the cumulative amount of BDP that diffused through the epidermis was statistically significantly greater for the CAL/BDP cream compared to the CAL/BDP TS at all time points. In addition, consistently higher amounts of BDP were recovered following CAL/BDP cream application than following CAL/BDP TS application at 1, 2, 4, and 8 h following application utilizing the in vivo tape stripping technique. CONCLUSION: The novel PAD technology-based cream formulation delivered more BDP into the upper stratum corneum and lower epidermis than a traditional topical suspension.

RESUMO

BACKGROUND: Since 1936, injectable carboxytherapy has been used for the treatment of circulatory issues and lack of tissue trophism. In the last 25 years, it has been applied to aesthetic issues, especially those related to the signs and symptoms of skin aging. Presently, carboxytherapy is available as a combination of transcutaneous gels that produce CO2 with benefit for atrophic skin. OBJECTIVE: The objective of this study was to investigate the efficacy and safety of a topical carboxy mask on facial photoaging after short term use of 4 weeks and long term use of 10 weeks. METHODS: The short term study was conducted for 14 days after 3 times weekly application of the facial mask for 1 h followed by a regression phase with evaluations at days 21 and 28. 11 healthy female subjects age 45-75 years were enrolled. Subjects applied the facial mask for 45 min, 3 times per week during the 2-week treatment period. The long term study was conducted for 10 weeks on 35 subjects 35-65 years with mild to moderate facial photoaging of Fitzpatrick skin types I-VI. Subjects underwent photography, elasticity, hydration, and VAS questionnaire assessments. RESULTS: The short term 4 week study demonstrated improvement in laser-Doppler measured blood flow and skin hydration. The long term 10 week study demonstrated improvement in firmness (16%, p = 0.001), sagging (9%, p = 0.023), and overall skin appearance (12%, p = 0.002). These findings were supported by the retraction time decrease at week 10 (-10%, p = 0.05). SUMMARY: The combination of two gels produced the liberation of CO2 , which improved short term skin hydration after 4 weeks of use and improved longer term skin elasticity after 10 weeks of use.

RESUMO

BACKGROUND: The recent removal of hydroquinone from the over-the-counter market has created a need for modern skin lightening formulations. An effective pigment lightening formulation must be non-irritating to prevent skin darkening from post-inflammatory hyperpigmentation, penetration enhanced to reach the epidermal/dermal junction, contain anti-inflammatory ingredients, and address multiple mechanisms of pigment production. OBJECTIVE: The objective of this research was to demonstrate the efficacy of a topical multimodal pigment lightening preparation containing tranexamic acid, niacinamide, and licorice. METHODS: Fifty female subjects 18+ years of all Fitzpatrick skin types with mild to moderate facial dyspigmentation were enrolled. Subjects were provided with the study product for twice daily use on the entire face and an SPF50 sunscreen with evaluations occurring at Week 4, Week 8, Week 12, and Week 16. The investigator used a face map to identify a pigmented target site on the face for dermaspectrophotometer (DSP) measurement. The dermatologist investigator completed a baseline facial efficacy and tolerability assessment. The subjects completed a tolerability assessment. RESULTS: 48/50 subjects completed the study without tolerability issues. The DSP readings demonstrated a statistically significant reduction in target spot pigmentation at Week 16. The investigator assessed a 37% decrease in pigment intensity, a 31% decrease in pigment extent, a 30% decrease in pigment homogeneity, a 45% improvement in brightness, a 42% improvement in clarity, and a 32% improvement in overall facial skin dyspigmentation at Week 16. CONCLUSION: The combination of penetration enhanced tranexamic acid, niacinamide, and licorice was effective in inducing facial pigment lightening.

RESUMO

Objectives: Evaluate the effects of a new antioxidant containing topical allyl pyrroloquinoline quinone (TAP) on expression of key markers and assess the efficacy and tolerability in subjects with photodamaged skin. Methods: Donor skin tissue was irradiated prior to and following application of study products (TAP; a leading antioxidant cream [L-VC]). Expression of markers related to epidermal homeostasis and oxidative stress were assessed at 48 hours and compared to untreated, irradiated control (n=3 each). Evaluation of lines/wrinkles, skin texture, skin tone, dullness, and erythema from baseline occurred over 12 weeks in subjects with mild-to-moderate photodamaged skin. Histological evaluation occurred at Weeks 6 and 12 (n=4). Results: Following application of TAP, significant expression of markers related to epidermal homeostasis and repair, recycling and removal, and oxidative stress were demonstrated, compared to control (p<0.05). Reduced expression of collagen degrading enzymes, compared to control, were observed (p<0.05). Application of L-VC demonstrated nonsignificant expression of markers versus control. In 40 subjects evaluated over 12 weeks, significant mean improvements from baseline were observed at Week 4 in skin texture and dullness (both p<0.0001) and skin tone and lines/wrinkles (both p=0.01). The study product was highly tolerable. Histologic evaluation demonstrated reductions in solar elastosis from baseline at Weeks 6 (33%, p=0.01) and 12 (60%, p=0.002). Conclusion: An antioxidant containing TAP addresses internal and external manifestations of photoaging. TAP demonstrated significant expression of key markers associated with epidermal homeostasis and counteracting oxidative stress. Significant, early improvements in the appearance of photodamaged skin and histological improvements in solar elastosis were observed.

RESUMO

BACKGROUND: Silymarin is the active component of milk thistle, which has antioxidant properties by scavenging free radicals and potential comedolytic properties. AIMS: This study aimed to assess the efficacy and safety of 0.5% silymarin-loaded antioxidant serum (SAS) used to treat mild-to-moderate acne. PATIENTS AND METHODS: A prospective, open-label pilot study was conducted. We enrolled 22 Korean acne patients who applied the 0.5% SAS on the whole face twice daily while continuing the current anti-acne medications. Grade of acne severity, individual lesion counts, sebum output levels, skin erythema, and melanin pigmentation were assessed. RESULTS: After a 4-week application, the modified Global Acne Grading Score (mGAGS), Global Evaluation Acne (GEA) scale, and the acne lesion counts were significantly decreased. Sebum secretion, skin pigmentation, and erythema were also reduced during the study period, yet only the melanin pigmentation index reached statistical significance. Subgroup analysis revealed that the patients who took the low-dose oral isotretinoin during the study period showed more noticeable improvements in skin sebum output and melanin pigmentation. Additionally, no adverse event was associated with using the 0.5% SAS. CONCLUSION: The 0.5% silymarin-containing antioxidant formulation improved acne's clinical severity and related skin biophysical parameters.

RESUMO

BACKGROUND: Humans are exposed to physical, biological, chemical, and psychological stressor throughout their life span. In recent years many medicinal plants have been shown to induce stress adapting and protective functions. Plant-derived extracts and vitamin E exhibit stress protection or resistance by normalizing cellular homeostasis and enhancing resistance to toxic stimuli to overcome cellular damage. Here we report the evaluation of a topical preparation (product test materials; PTM) containing an ingredient blend of Rhodiola Rosea, Eleutherococcus Senticosus (Siberian Ginseng), Rhaponticum Carthamoides, Inonotus Obliqus, and Slegainella Lepidophylla as the base formula and tested the addition of Lespedeza Capitata (leaf/stem) extract plus vitamin E and/or Aloe Vera to determine the induced protective functions in human skin when challenged with intrinsic and extrinsic stressors. METHODS: The base topical preparation plus Lespedeza Capitata extract plus vitamin E or the base topical preparation plus vitamin E and Aloe Vera were assayed in vitro on (a) intrinsically stressed excised abdominoplasty skin, (b) full thickness (FT) skin equivalent models post-treated with a combination of ultra-violet (UV) B light (250 mJ/cm2) and diesel particular matter (DPM) (75 µg/mL) skin, for their effect on antioxidant, inflammation, and stress biomarker geners. Additionally, the bioadaptive activity of the PTMs was confirmed in providing resilience and protection against UV-induced erythema. For example, in a clinical study, daily topical application of the PTMs on the buttocks of 20 woman (18-78 years old), average age of 51.1 years, median body mass index (BMI) of 26.5 for 8 weeks followed by 2 minimal erythema dose (MED) of UVB exposure was accessed 24 hours after irradiation. Statistical analysis was performed by t-test and ANOVA, repectively. RESULTS: Pretreatment with the topical PTMs on intrsinically stressed skin significantly reduced the expression of the stress gene biomarkers, p53, pro-inflammatory cytokines Interleukin-1ß (IL-1ß) and Tumor Necrosis Factor-α (TNFα) and the pro-apoptotic BCL2 associated X, apoptosis regulator (BAX) values compared to controls. Topical application of the PTMs on Full Thickness (FT) human skin treated with UVB light and DPM significantly enhanced the stress response by activating heat shock transcription factor 4 (HSF4) and heat shock protein family B (small) member 1 (HSPB1) gene levels belonging to the heat shock protein (HSP) family by significantly increasing the expression of heme oxygenase 1 (HMOX1). At the same time, significantly reducing IL-1ß levels were observed plus protection of skin cells from toxicity ocurred by significantly increasing the expression of B-cell lymphoma 2 (BCL2) (anti-apoptotic gene). In the clinical study, daily topical applications of the PTMs for 8 weeks followed by 2MED of UVB irradiation with clinical assessment 24 hours later revealed a significantly reduced intensity of erythema when compared to the buttock region treated with UVB alone. CONCLUSIONS: The PTMs containing adaptogen ingredients may confer stress resistance and induce stress protective responses against intrinsic as well as extrinsic stressors as demonstrated by the obtained in vitro and clinical evidence.

RESUMO

BACKGROUND: Permanent hair dye is the most commonly used anti-aging procedure used by both men and women. However, permanent hair dye can cause irritant contact dermatitis due to ammonia and allergic contact dermatitis due to paraphylenediamine (PPD). METHODS: This research examined an ammonia-free and PPD-free permanent hair dye in 50 ethnically diverse females 21-91 years of age who were current users of permanent hair dyes. Subjects were patch tested prior to dyeing. Two dye sessions were undertaken at baseline and 2-6 weeks post-baseline depending on the dyeing habits of the subject. RESULTS: 50/50 subjects successfully completed the study with no incidence of allergic or irritant contact dermatitis. After 2 dyeing procedures, the dermatologists rated an 87% improvement in hair shine, 90% improvement in hair color, 88% improvement in hair moisturization, 87% improvement in hair porosity, and 88% improvement in hair combability. CONCLUSIONS: A MEA-based ammonia-free cream hair color without PPD or resorcinol was safe for use on the hair and scalp of females with diverse hair types and textures.

RESUMO

Introduction: This study examined the efficacy and tolerability of a once-daily regimen of a 3% salicylic acid treatment gel containing turmeric and a low concentration of salicylic acid plus shea butter exfoliating moisturizer when used as monotherapy or in as an adjunct to other Rx psoriasis medications. Patients and Methods: This single-site 12-week study enrolled 20 subjects >18 years of age with mild-to-moderate psoriasis involving <10% body surface area. Assessments were performed at baseline and Weeks 4, 8, and 12 using a 5-point scale (0 = none to 4 = severe). The investigator-assessed efficacy (changes from baseline for erythema, desquamation, induration, and overall global assessment [IGA]) and tolerability (irritation and edema). Study subjects assessed efficacy parameters of redness, scaling, and overall skin problems along with tolerability parameters of stinging, burning, itching, and irritation. Subjects applied the turmeric and salicylic acid treatment gel along with a moisturizer once daily to all affected areas. Results: Half (50%) of the subjects were using concomitant Rx psoriasis treatments, while the other 50% received the study psoriasis treatment regimen as monotherapy. Investigator assessments of erythema, desquamation, induration, and IGA scores showed significant reductions from baseline (P ≤ 0.021) at Weeks 4, 8, and 12. At Week 12, these reductions reached 48%, 46%, 51%, and 48%, for these parameters, respectively. The investigator observed no irritation or edema at any time point. Subject assessments of redness, scaling, and overall improvement demonstrated significant reductions in 8 of 9 assessments (P ≤ 0.037). The subjects reported mild irritation at Weeks 4, 8, and 12. No treatment compliance issues or adverse events related to study product occurred during the study. Conclusion: A once-daily over-the-counter (OTC) turmeric/salicylic acid gel followed by a shea butter/salicylic acid exfoliating moisturizer demonstrated excellent tolerability and efficacy in plaque-type psoriasis after 12 weeks of once-daily use.

RESUMO

BACKGROUND: New development of cell-targeted therapies to enable site-specific skin tissue drug delivery may reduce off-target effects, decrease unwanted toxicities, and enhance drug efficacy. These efforts have led to several targeting strategies that modulate active product delivery to include small molecule-, nucleic acid-, peptide-, antibody-, and cell-based strategies. Tissue specific cell-targeting strategies such as these may be useful in cosmetic dermatologic applications. OBJECTIVE: The aim of this 16-week clinical trial of a skin brightening composition containing melanocyte cell-targeted biodelivery was to assess its effectiveness in restoring the skin complexion evenness by modulating melanocyte activity in a cohort of 50 Fitzpatrick type I–VI subjects with moderate to severe dyspigmentation. RESULTS: Data from expert grading, skin surface colorimetry, and subject self-assessments reflected significant improvement in facial skin tone as early as 2 weeks after treatment initiation, with continual improvement through week 16. The most dramatic pigmentation improvement, based on investigator assessments, was a statistically significant improvement in skin brightness at week 2 that progressed to week 8 with significant improvement in skin evenness and brightness. By weeks 12 and 16, progressive levels of significant improvement in skin evenness and brightening became apparent. Colorimetry demonstrated progressive improvement in skin dyspigmentation starting at 2 weeks and continuing to week 16. Subject self-assessment data supported similar improvements in skin dyspigmentation. CONCLUSION: These results demonstrate the ability of a cell-targeted topical therapy to achieve improvements in skin pigmentation through site-specific suppression of melanocyte activity.

RESUMO

BACKGROUND: Inflammatory papulopustular rosacea produces sensitive facial skin. Thus, medications designed for rosacea require careful vehicle development to insure optimal drug delivery in an environment suitable for barrier repair. OBJECTIVE: The objective of this phase 1 study was to elucidate the barrier effects of an investigational topical minocycline anhydrous gel 3% in subjects with inflammatory rosacea. METHODS: 31 male or female subjects with all complexion types and moderate facial rosacea, defined as 15+ inflammatory facial lesions, were enrolled in this single-site study to evaluate the effects of an investigational topical 3% minocycline anhydrous gel vehicle on skin barrier function; the new topical minocycline gel is an investigational product under development and has completed a phase 2b study in rosacea patients. Following a 30-minute acclimation period, subjects underwent a one-minute transepidermal water loss (TEWL) measurement on the left cheek and triplicate pin probe corneometry measurements from the right cheek. Subjects used the investigational topical 3% minocycline anhydrous gel every evening and returned to the research center at day 1, week 2, and week 4. RESULTS: 30/31 subjects completed the research study. The study medication produced a 23% (P=0.003) increase in skin hydration at day 1 and maintained the hydration increase with a 22% (P=0.003) increase at week 2 and a 20% increase (P=0.001) at week 4. Simultaneously, skin barrier function also improved with an 11% reduction in TEWL at day 1 followed by an 18% reduction in TEWL at week 2 (P=0.001) and a 28% decrease in TEWL at week 4 (P<0.001). This improvement in skin barrier was due to a combination of skin healing and the moisturizing properties of the investigational topical 3% minocycline anhydrous gel medication evaluated in this study. CONCLUSION: The investigational topical 3% minocycline anhydrous gel decreases TEWL, indicating barrier repair, while increasing corneometry measurements, indicating improved skin hydration.

RESUMO

The original article “The Skin Health and Beauty Pyramid” was published in 2014. In the last 7 years, many new skin care innovations have been developed that were not available at the time of the first publication. New mechanisms of action for recently identified unmet skin aging needs along with novel ingredients have been commercialized that warrant the attention of dermatologists, skin care professionals, and patients. This article updates the original pyramid with these new concepts. J Drugs Dermatol. 2021;20(6):695-699. doi:10.36849/JDD.5883 THIS ARTICLE HAD BEEN MADE AVAILABLE FREE OF CHARGE.
