Abstract

Background. The phenomenon of global warming increases the urgency of protection for humans to avoid the negative effects of exposure to Ultraviolet (UV) radiation. The depletion of the ozone layer can cause skin damage to the molecular level which then increases the thickening and aging of the skin, to the possibility of skin cancer in humans. Sunscreen can provide protection from the effects of radiation caused by UV rays. In the use of sunscreen, the term SPF (Sun Protecting Factor) is also known which is a reflection of how long UVA and UVB can provide radiation to human skin. The low level of one's knowledge about the adverse effects of UV exposure is a factor in the occurrence of skin cancer in humans. Purpose.
