Abstract: Ultraviolet light is an electromagnetic wave emitted from sunlight which is divided into 3 wavelengths. UV wavelengths, divided into UVA rays, UVB rays and UVC rays. UVC rays will be trapped in the ozone layer and UVA radiation can reach (90-95%) while at UVB will be less (<10%). The body needs special protection from UV radiation, especially on organs that are exposed to direct sunlight, namely the skin. Sunscreen is a compound that functions as skin protection from excessive sun exposure, especially from exposure to ultraviolet (UV) rays. Sunscreen is divided into 2 types, namely physical sunscreen and chemical sunscreen.
