How Effective Is Your Sunscreen?

Memorial Day Weekend is fast approaching and that means people will be stocking up on sunscreen. But just how effective are those products?

Consumer Reports tested 65 lotions, sprays, and sticks all labeled with SPF's of 30 or higher. They found many do not live up to their promise because 43 percent failed to meet SPF claims, and two marketed for children failed by huge margins.

"Banana Boat Kids" and "CVS Kids" both claim to have an SPF of 50, but actually had a sun protection factor of 8.

Another finding -- sunscreens with chemicals provide better protection than natural or mineral-based products. Doctors say nothing will work unless you use enough, about two tablespoons for your entire body, and reapply frequently.
