Used in skincare and dermatological formulations due to its natural presence in the skin and its role in UV protection. It acts as a photoprotectant by absorbing ultraviolet radiation, helping to shield skin cells from UV-induced damage. Its ability to undergo reversible isomerization upon UV exposure makes it a subject of interest in studies on photoaging and immune modulation in the skin. Also investigated for its potential anti-inflammatory properties and role in maintaining skin barrier function.
