What labels on sunscreens won’t tell you

Despite words like “broad spectrum” and “waterproof” on the labels, sunscreens don’t’ completely block the sun’s UVA and UVB rays, and none are totally waterproof. Finally, the Food and Drug Administration is changing label rules so that by next year, buying sunscreen will be easier. One improvement: “broad spectrum” will mean the product was tested to make sure that you’re protected from both types of rays. Two sunscreens in the latest tests that provided top UVA and UVB protection are Target’s Up & Up Sport SPF 30 and Equate Baby SPF 50, from Walmart.
