Brief summary
The study aims at evaluating skin wrinkling, puffiness and fatigue and dark circle appearance on asian and african-american healthy volunteer cohorts receiving a cosmetic formulation containing NMN (2%). The product will be evaluated after 28 and 56 days of twice-daily application in comparison with a reference cosmetic formulation using clinical scoring under dermatological control. Cosmetic acceptability and future use will also be subjectively evaluated by analysis of the subjects answers to an evaluation questionnaire.
