Zinc Oxide, a naturally reflective white powdered natural mineral, is commonly used to provide broad-spectrum sun protection in physical sunscreens. Unlike chemical sunscreens—which filter aging UVA/UVB rays—mineral sunscreens physically block them. When used as directed, mineral sunscreens with Zinc Oxide can help prevent sunburn and reduce the risk of skin cancer and early skin aging caused by the sun.
