It is included in formulations targeting wrinkles and skin elasticity due to its ability to protect cells from environmental damage. In hair care, it promotes scalp health and may support hair growth by improving blood circulation. Commonly found in serums, creams, and toners, it is valued for enhancing skin hydration and barrier function. Also used in dietary supplements for potential cognitive and metabolic benefits, though topical applications are most prevalent in cosmetics.
