Sunscreens are products that absorb or block ultraviolet (UV) radiation from the sun, helping to protect people from sunburn and reduce the risk of skin cancer. Mineral sunscreens, also called sunscreens or physical sunscreens, contain ingredients like titanium dioxide or zinc oxide and protect the skin by blocking the sun's harmful UV rays. Chemical sunscreens contain carbon-containing molecules that absorb sunlight, such as oxybenzone, octinoxate, octisalate, and avobenzone.
