레스베라트릴 트라이아세테이트(RTA)를 함유한 크림의 피부 노화 완화 효과

Skin aging degree can be objectively measured using the instrumental analysis. The purpose of this study was to evaluate the anti-aging effects of a cream containing 8000 PPM of resveratryl triacetate (RTA) in the human skin test. Twenty female subjects were given test products twice a day for 8 weeks on the face, and wrinkles, sagging, elasticity, dermis denseness, moisture and brightness were measured every 4 weeks by instrument analysis. After 4 and 8 week-use of the test product, total wrinkle area decreased (5.12%, 4.86%), total wrinkle volume decreased (10.53%, 8.41%), sagging decreased (4.69%, 5.91%), elasticity increased (2.84%, 3.98%), dermis denseness increased (15.65%, 20.80%), water content increased (5.83%, 7.37%), lightness (L* value) increased (0.79%, 1.07%), and individual typology angle (ITAo) increased (5.43%, 4.95%)compared with the baseline values before treatments, and all these changes were statistically significant (p < 0.05). No adverse skin reactions were observed in all participants during the study period. This study supports the anti-aging effects of the test product.
