Vitamin C and peptides are widely used in cosmetic products but there is a paucity of clinical studies showing that the formulations are effective in treating signs of facial aging.
These 3 clinical studies evaluated the effectiveness of an anti‐aging formula containing natural vitamin C (10%), biopeptides (rice and lupin), hyaluronic acid, and Vichy volcanic mineralizing water, in amber glass ampoules with no preservatives (Peptide‐C ampoules).
Dansyl chloride fluorescence labeling compared cell turnover for Peptide‐C ampoules vs untreated skin in 32 female subjects.
Study 2, an open clinical study, evaluated the efficacy on wrinkles of Peptide‐C ampoules by investigator clinical scoring based on Dynamical Atlas visual assessment (N=40) and subject self‐assessment questionnaires (N=47).
Study 3, an open clinical study, evaluated wrinkles by instrumental quantification with 3D fringe projection analysis (N=40) and subject questionnaires (N=51).
