FDA Regulates Sunscreen Safety Amidst 'Nontoxic' Marketing Claims
The U.S. Food and Drug Administration (FDA) regulates sunscreens as over-the-counter drugs due to their health claims, such as preventing sunburn and reducing the risk of skin cancer and premature aging. Despite the marketing of sunscreens as 'nontoxic,' 'clean,' or 'natural,' these terms are not legally defined in the U.S., allowing brands to use them without meeting specific standards. The FDA evaluates sunscreen ingredients based on the 'generally recognized as safe and effective' (Grase) standard. Currently, only zinc oxide, titanium dioxide, and bemotrizinol are considered Grase. Dermatologists emphasize the importance of using sunscreen to protect against UV radiation, which is a significant risk factor for skin cancer.
