ABSTRACT
INTRODUCTION: Peptide-C ampoules (PC) contain peptides, 10% of vitamin C, hyaluronic acid, and Vichy volcanic mineralizing water. AIMS: To assess the effectiveness and tolerability of PC. PATIENTS AND METHODS: An observational study conducted in 9 countries in women ≥30 years old with signs of facial skin aging (grade >0 for forehead and/or crow's feet wrinkles and bothered by skin quality). Investigator assessments and subject questionnaires were performed at initial visit and Day 30 after application of PC twice daily for 28 days. Tolerance was assessed throughout the study. RESULTS: Effectiveness and safety were analyzed in 1382 and 1742 subjects, respectively. Most subjects (mean age 48.5 ± 8.6 years) had skin phototype II or III (91.7%) and dry or combination skin (63.9%). PC was used as a standalone care or prior to a planned procedure (70%), or after a procedure (30%). Between baseline and Day 30, 63% and 64% of all subjects (N = 1360) had an improvement in forehead wrinkles and crow's feet wrinkles, respectively. Skin hydration improved in 67.3% of subjects. According to investigator and subject assessments, skin quality, skin radiance, skin aging signs, wrinkles, complexion, and skin pores significantly improved by Day 30. Similar results were observed for subgroup analyses when PC was used as standalone skin care or after a procedure. Tolerance of PC was rated as good to very good by 97.7% of subjects. CONCLUSIONS: Peptide-C ampoules is effective in reducing visible signs of skin aging, and well tolerated, when used alone or as an adjunct to anti-aging procedures.
