A Clinical Study to Evaluate the Long-Term Efficacy and Tolerability of a Daily Anti-Aging Daily Serum

This double-blind, randomized, placebo-controlled, single-center clinical trial was conducted to assess the efficacy and tolerance of an anti-aging daily serum (Cell 1) to improve moderate overall photodamage and skin fatigue of aging skin after 12-weeks days of twice-daily use when compared to the efficacy of a combination of a placebo-control (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, week 4, week 8, and week 12. 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 at baseline and post-baseline by a clinical grader, a board-certified dermatologist. Furthermore, blinded photo-grading at baseline and week 12 were performed by two board certified dermatologists. Self-assessment questionnaires, Antera 3D image, Ultrasound Imaging, and VISIA photography were completed at baseline and post-baseline timepoints. Furthermore, 10 randomized subjects, a subset of the study (five in Cell 1 and five in Cell 2) had 2 mm punch skin biopsies collected from the lateral, pre-auricular at baseline and week 12. A total of 62 subjects completed study participation (31 in Cell 1 and 31 in Cell 2).
