Benzophenone-3(UV9), often labeled as oxybenzone in sunscreen products, is a widely used chemical compound in cosmetics and sunscreens. This organic UV filter serves as a sunblock agent, absorbing and dissipating harmful ultraviolet (UV) rays, particularly UVB and some UVA radiation. Benzophenone-3 helps protect the skin from sunburn and UV-induced damage, making it a common ingredient in sunscreens, lotions, and lip balms.
