Evaluating the Impact of Oleocanthal and Oleacein on Skin Aging: Results of a Randomized Clinical Study

Abstract

The prevalence of skin aging and the request for effective treatments have driven dermatological research towards natural solutions. This study investigates the anti-aging efficacy of two bioactive natural polyphenols, Oleocanthal and Oleacein, in a skincare formulation. A single-blind, randomized clinical trial involved 70 participants, using a comprehensive exclusion criterion to ensure participant safety and study integrity. Participants applied the Oleocanthal and Oleacein 1% serum formulation twice daily for 30 days. The efficacy was objectively assessed using the VISIA® Skin Analysis System at baseline, after 15 days, and after 30 days. Results indicated significant wrinkle reduction in most groups. For women aged 45–79 years, the mean change was −33.91% (95% CI: −46.75% to −21.07%). For men aged 20–44 years, it was −51.93% (95% CI: −76.54% to −27.33%), and for men aged 45–79 years, it was −46.56% (95% CI: −58.32% to −34.81%). For women aged 20–44 years, the change was −25.68% (95% CI: −63.91% to 12.54%), not statistically significant. These findings highlight the potential of EVOO-derived polyphenols in anti-aging skincare, particularly for older adults. This research paves the way for further exploration into natural compounds in dermatology, particularly for aging skin management.
