The Food and Drug Administration (FDA) has announced that sunscreen products meeting modern standards for effectiveness may be labeled with new information to help consumers find products that reduce the risk of skin cancer and early skin aging, in addition to helping prevent sunburn.
The regulation allows sunscreens that pass the FDA's test for protection against ultraviolet A (UVA) and ultraviolet B (UVB) radiation to be labeled as "broad spectrum." UVA and UVB radiation contribute to sunburn, skin cancer, and premature skin aging. Sunburn is primarily caused by UVB radiation.
Under the new rules, manufacturers of sunscreens labeled as broad spectrum and SPF 15 or higher may state that the products will help prevent sunburn and reduce the risk of skin cancer and early skin aging. Products that have SPF values between 2 and 14 and pass the FDA's test may be labeled as broad spectrum, but the manufacturers may not state that these products reduce skin cancer risk or early skin aging.
Any product that is not broad spectrum, or that is broad spectrum but has an SPF between 2 and 14, must carry a warning stating that the product has not been shown to help prevent skin cancer or early skin aging.
More information on sunscreens is available from the FDA online.
