Take a minute to read the labels before you buy sunscreen. The FDA has issued new rules and there are two phrases you should understand.
1) "Broad Spectrum" means the product protects you against both UVA (aging) and UVB (burning) rays. Both are linked to cancer and cause wrinkles.
2) "Water Resistant" indicates when swimmers should reapply (40 mins after lighter formulas, 80 mins for more enduring ones).
Remember, what's more important than the SPF number on the product is how often you reapply, especially when sweating or doing a sport. Also important, wear your sunblock DAILY. We are even exposed to damaging rays under cloudy skies!
Have a fabulous summer. And make it a safe one!
