Background  Allegations on the benefits of incorporating vitamin C, vitamin E, and combinations thereof in topical skincare formulations are mostly based on in vitro and ex vivo experiments and/or limited protocols of specific stress conditions (pollution, UV exposure, laser irradiation,…).    Objective  To evaluate the instrumentally measurable effects and quantitative consumer perceptions of a protective and reparative serum on a panel of volunteers under normal nonstressed conditions of use, employing FOITS technology and innovative self‐assessment methods.    Method  In an open‐label study women of ≥40 years with visible signs of photoaging applied a serum comprising  l ‐ascorbic acid USP (15% w/v), tocopheryl acetate USP, and 5 ppm palmitoyl tripeptide‐38 to the face once daily for 56 days. Skin roughness and isotropy changes were evaluated on days 0, 28, and 56, visual instrumental evaluation of skin‐tone parameters was assessed on days 0 and 56. Subjects completed self‐assessment questionnaires every third day of the trial period for radiance, homogeneity, and wrinkle appearance.    Results  Skin‐roughness parameters decreased significantly by 8%‐9% ( P  < .05) and subjects experienced a significant increase in skin isotropy ( P  < .05). Photographic analysis revealed significant improvements in skin tone, with a 9% decrease in redness and 8% increase in homogeneity ( P  < .0001 for both), in excellent agreement with subjects' perception of significant improvements of radiance, complexion, and wrinkles.    Conclusion  The study confirms statistically significant correlation between objectively measured and quantitative subjectively perceived benefits of the bespoke serum containing antioxidants and a matrix‐restoring peptide.
