Solamarine is widely used in cosmetic and skincare formulations for its photoprotective properties. It helps protect skin cells from UV-induced damage by stabilizing cellular structures and reducing oxidative stress. Due to its ability to absorb ultraviolet radiation, it is incorporated into sunscreens and anti-aging products to enhance protection against photoaging. It is also used in after-sun care products for its soothing and regenerative effects on sun-exposed skin. Additionally, Solamarine finds application in hair care products, where it protects hair proteins and pigments from UV degradation, helping maintain color and strength in sun-exposed hair.
