The FDA is changing long-standing rules on sunscreen labeling, requiring that sunscreens protect against both UVA and UVB radiation in order to be labeled “broad spectrum.” By this summer, OTC sunscreen manufacturers will have to follow this new regulation, along with a few others. Many common phrases used on sunscreens, such as “sunblock,” “waterproof,” “sweatproof,” and “prevents skin cancer,” will no longer be permitted by the FDA. The length of time that the product is “water resistant” will need to be used instead. The new regulations will also require an SPF rating of 15 or higher in order to claim that the product helps prevent sunburn or skin cancer. The new regulations will also apply to moisturizers and cosmetics that contain sunscreen.
