Sunscreens and Photoaging: An Update

UV radiation (UVR) can lead to the development of nonmelanoma skin cancers (NMSCs) and pre­mature skin aging. Sunscreens are safe and effective in protecting against photocarcinogenesis and photoaging. Many types of sunscreens are available, including organic and inorganic products, as well as those containing antioxidants and other additives that may enhance the protective quali­ties of a sunscreen. Additionally, the new US Food and Drug Administration (FDA) policy on sun­screen labeling and testing ensures that consumers are offered protection against both UVA and UVB radiation. If photodamage does occur, there are many treatments available to improve both the medical and cosmetic consequences of sun damage. Regular and appropriate sunscreen use minimizes the risk for developing skin cancer and slows the process of premature skin aging.
