Effects of Hippohae rhamnoides Extracts on Skin Conditions

Abstract

Purpose: In this study, a human application test was performed to verify the skin improvement effect of Hippophae rhamnoides (H. rhamnoides) fruit oil and hot-water extracts to improve wrinkles around the eyes, facial cheek lifting, skin elasticity, skin density, skin tone, spots and pigmentation as ingredients for cosmetics. To meet this purpose, this study has focused on the development and commercialization of new natural ingredients. Methods: This study conducted a human application test to verify the skin improvement effect of H. rhamnoides fruit oil and hot-water extracts in 20 adult women aged 30-60 years old. By applying ANTERA 3D, we evaluated wrinkles around the eyes, improved facial cheek lifting, and spots and pigmentation, evaluated skin elasticity improvement using a Ballistometer, and evaluated skin density improvement by applying DUB® SkinScanner. The skin tone improvement was evaluated by applying a photometer and an anterior eye imaging system. Results: After 3 and 6 weeks of treatment, the rates of improvement at the areas where the test material was applied were respectively 6.75% and 12.86% at the wrinkles around the eyes, 31.15% and 44.63% for facial cheek lifting, 2.46% and 4.28% for skin elasticity, 6.12% and 9.63% for skin density, 1.12% and 1.63% for skin tone, and 1.60% and 2.46% for spots and pigmentation. Conclusion: As a result, the effects of H. rhamnoides fruit oil and hot-water extracts for reducing skin wrinkles, blemishes, and pigmentation, and improving facial cheek lifting, skin elasticity, density, and skin tone were verified. We believe that H. rhamnoides fruit oil and hot-water extracts can be used as a new skin anti-aging cosmetic ingredient.
