A Clinical Study to Evaluate the Efficacy of an Anti-Aging Serum

This double-blind, randomized, controlled, single-center clinical trial was conducted to assess the efficacy and tolerance of an anti-aging serum to improve moderate overall photodamage and skin fatigue of aging skin after 7 days of twice-daily use when compared to the efficacy of a combination of anti-aging serum and an anti-aging facial moisturizer. A total of 26 female subjects, aged 34-60, completed study participation.

This double-blind, randomized, controlled, single-center clinical trial was conducted to assess the efficacy and tolerance of an anti-aging serum (Cell 1) to improve moderate overall photodamage and skin fatigue of aging skin after 7 days of twice-daily use when compared to the efficacy of a combination of anti-aging serum and an anti-aging facial moisturizer (Cell 2). Skin fatigue was characterized by dehydrated skin with a lack of firmness (visual) and a dull appearance on the global face.

Efficacy and tolerability were assessed through clinical grading at baseline, day 3, and day 7. Efficacy evaluation on fine lines and wrinkles in the crow's feet area; overall eye appearance on the periocular area; and smoothness (tactile), firmness (visual), radiance, and overall photodamage on the global face were performed 15 minutes post product application. Self-assessment questionnaires, Glossymeter measurements, and VISIA photography were completed at baseline, day 3, and day 7.

A total of 26 subjects completed study participation, which included 12 subjects in Cell 1, and 14 subjects in Cell 2.
