With the unofficial start of summer just a few days away, many people will soon be stocking up on sunscreen. The products they’ll be seeing in stores look different than they have in the past. That’s because new rules for sunscreen labels are now in effect. The changes are good ones for consumers. The new rules, mandated by the FDA, are making sunscreen more informative with less misleading information. For example, the term “sunblock” is banned because none of these products can block all of the sun’s ultraviolet rays. “Waterproof” is also banned, replaced by “water-resistant”—which must be accompanied by a set time for reapplication. Another big change has to do with SPF, or sun protection factor. The best protection comes from a sunscreen that provides broad spectrum protection, meaning it filters out much of the UVA and UVB. Under the new FDA rules, if a label says “broad spectrum,” the product must pass tests proving that it truly protects against both UVA and UVB rays. Sunscreen products that don’t meet an SPF of 15 or higher for both UVA and UVB must now carry a warning.
