Could your sunscreen do more harm than good?

"I'm concerned with the lack of safety testing with sunscreens," says Dr. Rebecca Sutton, a staff scientist with the EWG. There is a long list of ingredients that are potentially harmful, or even cancer causing, that we just don't know enough about.

This is especially worrisome when it comes to children. 

The surface area of a child's skin relative to his body weight is much greater than adults, so any chemical applied to a child's skin is about 1.4 times more potent.

Oxybenzone is a common sunscreen ingredient that has been linked to a host of problems, including allergies, hormone disruption and cell damage. Oxybenzone may also helps other chemicals penetrate the skin. The good news is, oxybenzone is getting easier to avoid and most brands now offer blends without oxybenzone. You just have to read the labels.
