Sun-proofing your child's skin

Protect from day one. The first line of defense for a baby younger than six months old should be proper clothing (lightweight long pants, brimmed hats, long-sleeved shirts) and shade. If neither is available, the American Academy of Pediatrics recommends applying sunscreen that has at least SPF 15.

Choose a physical sunscreen. A physical sunscreen (such as MD Moms Baby Silk Babysafe Sunscreen Towelettes) that contains pure physical block ingredients like zinc oxide and titanium dioxide offers the safest protection and reduces the risk of skin irritation. As a rule of thumb, if sunscreen is more than two seasons old, it's time to replenish.

Don't skimp on the sunscreen. If no irritation occurs, use one ounce (the size of a shot glass, or a palm full) for each application. (This should be 1.5 ounces for an adolescent or adult.) Apply twice to areas of the skin that wear against clothing or sweat frequently. With a chemical sunscreen, apply one layer to your child's face and body, then reapply after 20 minutes to catch any missed spots.

Pay attention to time and place. Since the most damaging UV radiation happens during the peak hours of the day -- from 10 a.m. to 4 p.m. -- avoid sun exposure during that time or find a shady area for your children to play outdoors. Remember to apply (and reapply) sunscreen to your child, even if she's in the shade. Reapply every 3-4 hours when dry, and every 1-2 hours if swimming, wet or sweaty.

Don't stop at sunscreen. In addition to consistent sunscreen use, appropriate clothing is also key for optimal protection from the sun. Dress your child in clothes with UV protection (try Cabana Life's line). Also, an SPF rinse on tightly woven cotton clothing can increase the SPF value from 5 (the SPF value of an average T-shirt) to 30.

By taking these simple steps to protect your children's skin this summer -- and during any season -- you can make sure they enjoy the sun safely.
