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.
