INDIVIDUAL ARTICLE: Skincare in Skin of Color: A Comprehensive Approach to Preprocedure, Intraprocedure, and Postprocedure.

Hyperpigmentation, uneven skin tone, textural changes, and dull skin are common cosmetic concerns in skin of color. Other signs of aging, including fine lines, deeper wrinkles, and skin laxity, also occur but may present in later decades. In-office procedures such as laser treatments, energy devices, toxins, fillers, and chemical peels are useful options for addressing the most common cosmetic concerns in skin of color patients. Skincare can play an important role in improving cosmetic outcomes when used in conjunction with in-office procedures. With the availability of these approaches, clinicians can now integrate in-office procedures with skincare strategies to offer patients with skin of color a comprehensive treatment plan that meets their needs.

Influence of Season on Efficacy and Tolerability of Tazarotene 0.045% Lotion for the Treatment of Acne.

Objective: The condition of the skin can vary due to weather fluctuations. Therefore, this post-hoc analysis evaluated efficacy and safety of tazarotene 0.045% lotion in warmer versus colder months. Methods: In two Phase III, double-blind, 12-week studies, participants aged nine years or older with moderate-to-severe acne were randomized 1:1 to once-daily tazarotene or vehicle lotion. The pooled population (N=1,614) was stratified by randomization date (warmer=May to September; colder=October to April). Evaluations included inflammatory/noninflammatory lesion counts, treatment success, adverse events, and safety/tolerability. Results: Tazarotene 0.045% lotion was similarly efficacious over colder and warmer months. Compared with vehicle, tazarotene demonstrated significantly greater least-squares mean absolute reductions from baseline to Week 12 in inflammatory (colder/warmer tazarotene vs. vehicle: -16.6/-15.8 vs. -13.2/-12.9) and noninflammatory lesions (-23.2/-22.6 vs. -17.5/-15.1); treatment success rates were also significantly higher (30.1/30.8% vs. 18.2/17.6%) (P<0.001, all). No strong seasonal trends in safety were observed, though tazarotene led to slightly more discontinuations (3.4% vs. 1.9%) and related adverse events (12.0% vs. 10.3%) in colder versus warmer months. Transient increases in scaling, erythema, and itching at Weeks 2 to 8 of tazarotene treatment were slightly higher in colder versus warmer months but returned to baseline/improved by Week 12. Limitations: Geographical variation across study sites can lead to varying temperatures and humidity within the same months. Conclusion: Tazarotene 0.045% lotion was efficacious and well tolerated for acne treatment, regardless of season. Year-round tolerability of tazarotene 0.045% lotion may be due to its lower tazarotene concentration and polymeric emulsion technology, which simultaneously delivers moisturizers/humectants/emollients to skin.

Atopic Dermatitis and the Role of the Skin Microbiome in Choosing Prevention, Treatment, and Maintenance Options.

BACKGROUND: Atopic dermatitis (AD) is a common skin condition characterized by disturbed barrier function, skin inflammation, and cutaneous dysbiosis. Clinically, it manifests as chronic-recurrent xerosis, pruritus, and erythematous lesions. Its pathophysiology is complex, making the selection of appropriate treatment options a task. AIM: To share insights gained from a literature review and discussions with experts in dermatology on key factors related to the prevention, treatment, and management of AD in relation to the skin microbiome. METHODS: Results from an expert panel were summarized and discussed to provide updated recommendations for the treatment and maintenance of AD. RESULTS: Evidence supports a strategy for managing inflammatory skin diseases with a selenium-rich post-biotic thermal water and biomass containing moisturizer. The moisturizer helps to restore homeostasis of the skin, re-populate a diverse microbiome, encourage the growth of commensal bacteria, and improve barrier function and symptoms of AD. CONCLUSIONS: Normalization of skin microbiome diversity using a topical moisturizer containing post-biotic aqua and biomass may offer a valuable option for the treatment and maintenance of inflammatory skin diseases. Clinicians should discuss the benefits of this treatment in the context of a full AD management program that covers prevention, active treatment, and maintenance.

The Effects of Once-Daily Tretinoin 0.05% Lotion on Quality of Life in Patients with Moderate-to-Severe Acne Vulgaris.

BACKGROUND: In two phase III clinical trials of patients with moderate-to-severe acne (NCT02932306, NCT02965456), tretinoin 0.05% lotion reduced inflammatory and noninflammatory lesions relative to vehicle lotion, with low potential for cutaneous irritation. OBJECTIVE: Data from these studies were analyzed post hoc to investigate the effects of tretinoin 0.05% lotion on patient-reported quality of life, as assessed using the Acne-Specific Quality of Life Questionnaire (Acne-QoL). METHODS: Mean changes from baseline to week 12 in Acne-QoL scores were analyzed in the pooled intent-to-treat population and a subgroup with treatment success (≥ 2-grade improvement on the Evaluator's Global Severity Scale and rating of "clear" or "almost clear"). Pearson correlations were conducted in the pooled intent-to-treat population to assess the relationship between the Acne-QoL acne symptoms domain and each of the other three domains. RESULTS: In the pooled intent-to-treat population (n = 1640), greater mean improvements were found with tretinoin 0.05% lotion vs vehicle in all four domains: self-perception (mean change: 7.4 vs 6.7); role-emotional (6.8 vs 6.0); role-social (4.8 vs 4.6); acne symptoms (6.5 vs 5.6); all p < 0.05. Relative to the intent-to-treat population, participants who experienced treatment success with tretinoin 0.05% lotion had higher (better) mean Acne-QoL scores at week 12. Correlations between acne symptoms and the other three domains were found at baseline and week 12 (p < 0.05). CONCLUSIONS: Participants with moderate-to-severe acne reported better quality of life after 12 weeks of treatment with tretinoin 0.05% lotion. Clinical improvements in acne symptoms may have contributed to these outcomes. TRIAL REGISTRATION: ClinicalTrials.gov: NCT02932306, NCT02965456.

Retinoids and azelaic acid to treat acne and hyperpigmentation in skin of color.

In this review, we examine published data reporting the efficacy of pharmaceutical agents to treat associated postinflammatory hyperpigmentation commonly seen in skin of color. Retinoids and azelaic acid have been widely used to treat acne. Now there are increasing data describing their use in skin of color for the treatment of both acne and the subsequent postinflammatory hyperpigmentation. Historically, some dermatologists have been hesitant to use retinoids in skin of color because of perceived hypersensitivity in this patient population. However, recent data support the use of retinoids and azelaic acid in skin of color as both safe and beneficial.
