According to the Washington Post, Sunbathers headed to the beach this summer will find new sunscreen labels on store shelves that are designed to make the products more effective and easier to use. But despite those long-awaited changes, many sunscreens continue to carry SPF ratings that some experts consider misleading and potentially dangerous, according to a consumer watchdog group.
A survey of 1,400 sunscreen products by the Environmental Working Group finds that most products meet new federal requirements put in place last December. The rules from the Food and Drug Administration ban terms like “waterproof,” which regulators consider misleading, and require that sunscreens filter out both ultraviolet A and B rays. Previously some products only blocked UVB rays, which cause most sunburn, while providing little protection against UVA rays that pose the greatest risk of skin cancer and wrinkles.
“The high SPF numbers are just a gimmick,” says Marianne Berwick, professor of epidemiology at the University of New Mexico. “Most people really don’t need more than an SPF 30 and they should reapply it every couple of hours.” Berwick says sunscreen should be used in combination with hats, clothing and shade, which provide better protection against ultraviolet radiation.
Per the FDA, “Labeling a product with a specific SPF value higher than 50 would be misleading to the consumer.” At the time the agency proposed capping all SPF values at 50 because “there is not sufficient data to show that products with SPF values higher than 50 provide greater protection for users.”
More than 76,000 men and women in the U.S. will be diagnosed with melanoma this year and 9,480 are expected to die from the aggressive form of skin cancer, according to the National Cancer Institute. The disease, which is often linked to ultraviolet exposure, is usually curable when detected early.
