Clinical Evaluation of a Nature-Based Bakuchiol Anti-Aging Moisturizer for Sensitive Skin.

ABSTRACT

BACKGROUND: Patients with sensitive skin find topical retinoid use for anti-aging purposes challenging due to irritation. Bakuchiol, a meroterpene from the Psoralea corylifolia seed, has retinol functionality through retinol-like regulation of gene expression. OBJECTIVE: This research examined the tolerability, efficacy, and barrier effects of a nature-based bakuchiol-containing cleanser and moisturizer in subjects with sensitive skin. METHODS: 60 female subjects Fitzpatrick skin types I–V age 40–65 years with sensitive mild to moderate photodamaged skin were enrolled in this 4 week study. A sensitive skin panel was constructed 1/3 eczema/atopic dermatitis, 1/3 rosacea, 1/3 cosmetic intolerance syndrome. Subjects used a nature-based cleanser and moisturizer twice daily and underwent transepidermal water loss (TEWL), corneometry, tolerability assessments, and efficacy assessments at baseline, 5–10 minutes post-application, and week 4. RESULTS: The skin care products were well tolerated and efficacious (P<0.001) in terms of investigator assessed improvement in visual smoothness, tactile smoothness, clarity, radiance, overall appearance, and global anti-aging. Cheek corneometry measurements demonstrated a statistically significant 16% increase in skin moisture content (P<0.001). CONCLUSION: A bakuchiol nature-based anti-aging moisturizer is well tolerated and effective in individuals with sensitive skin.J Drugs Dermatol. 2020;19(12) doi10.36849/JDD.2020.5522.
