Sunscreens in the United States: Current Status and Future Outlook. Adv Exp Med Biol. 2020;1268:355-379 Authors: Glaser KS, Tomecki KJ Abstract Incidence rates of nonmelanoma skin cancer and melanoma have been on the rise in the USA for the past 25 years. UV radiation (UVR) exposure remains the most preventable environmental risk factor for these cancers. Aside from sun avoidance, sunscreens continue to provide the best alternative protection. UVR directly damages DNA and causes indirect cellular damage through the creation of reactive oxygen species, the sum of which leads to cutaneous immunosuppression and a tumorigenic milieu. The current generation of sunscreens protect from UVR through two main mechanisms: absorption and deflection. In the USA, the Food and Drug Association (FDA) regulates sunscreen products which are considered over-the-counter drugs. With the release of new FDA testing and labeling requirements in 2011 and the enactment of the Sunscreen Innovation Act in 2014, sunscreen manufacturers are now required to evaluate their products not only on the sun protection factor (SPF) but also on broad-spectrum UVA protection. The American Academy of Dermatology Association and the American Academy of Pediatrics have provided specific recommendations for proper sun protection and sunscreen usage with the continual goal of increasing public awareness and compliance with appropriate sun protective measures.
