Red and Black Currant Fruit Extract with Biotin Improves Skin Wrinkles and Reduces Hair Shedding in Healthy Women

The study evaluated a polyphenol-rich red and black currant fruit extract combined with biotin (RiboBeauty®) in 52 healthy women with mild-to-moderate facial wrinkles and excessive hair shedding. Participants consumed 500 mg/day of the currant extract plus biotin for 12 weeks. The intervention significantly improved skin and hair parameters compared with placebo. After 12 weeks, crow’s feet wrinkle area decreased by 18.5%, wrinkle volume decreased by 16.1%, and skin surface roughness was reduced by 14.7%. Hair health also improved, with hair shedding reduced by 37.2%, while hair density and overall hair appearance showed significant enhancement. The benefits were attributed to the high polyphenol content of the red and black currant fruits, particularly anthocyanins and other antioxidant compounds that help protect collagen, reduce oxidative stress, and support hair follicle function.
