Double-blind, Randomized Trial on the Effectiveness of Acetylhexapeptide-3 Cream and Palmitoyl Pentapeptide-4 Cream for Crow's Feet.

BACKGROUND: Crow's feet is one of the signs of skin aging. Many studies regarding skin aging have been carried out in Caucasians, as for Asians, there are different genotypes and phenotypes. Some anti-aging treatments carry a slightly higher risk of side effects and irritation in Asian skin. Currently, the use of topical active peptides for anti-aging, Acetylhexapeptide-3 (AHP-3) and Palmitoyl pentapeptide-4 (PPP-4), has been widely developed. This study aimed to investigate the anti-aging effects of AHP-3 and PPP-4 on the Asian patient with crow's feet.

METHODS: This study was a double-blind randomized trial using 21 Indonesian female subjects aged 26 to 55 years for eight weeks and divided into three groups: AHP-3 cream, PPP-4 cream, and placebo. The cream was applied twice daily to the periorbital area. The three groups were assessed using Corneometer, Tewameter, Cutometer, digital photography and Crow's Feet Grading Scale.

RESULTS: Based on clinical photos and data, improvements were found in several subjects using AHP-3 and PPP-4. PPP-4 appeared to demonstrate better results when compared to AHP-3 based on data, clinical photos, and self-assessment questionnaire.

CONCLUSION: PPP-4 demonstrated better results when compared to AHP-3 and placebo. This initial study provides an opportunity for further study with a more adequate number of samples and duration.
