School's out - and so is the sun. Learn how to keep your kids safe from its rays! The sun may be the mark of the summer, and your kids can play safely outside if they're wearing sunscreen. But here's the catch: you must apply it correctly. Start by applying a very thick layer of sunscreen. Use so much that it becomes hard to rub it all in. With sunscreen, timing is everything. To get the benefits, you must apply it half an hour before your kids go outside. Reapplying every two hours is also necessary, even with waterproof formulas! The DEET in insect repellants reduces the effectiveness of sunscreen, so increase the SPF if your kids are wearing bug spray. Proper sun safety also requires sunglasses. Luckily, most children love wearing them! Pick a pair of shades that protects against both UVA and UVB rays. And polycarbonate lenses are best, as they are the most shatter resistant. Most of the sun damage done to our skin occurs before age 18, so keep your kids protected today, and they'll thank you tomorrow!
