When dermatologist Adewole "Ade" Adamson sees people spritzing sunscreen as if it's cologne at the pool where he lives in Austin, Texas, he wants to intervene. "My wife says I shouldn't," he said, "even though most people rarely use enough sunscreen."
At issue is not just whether people are using enough sunscreen, but what ingredients are in it.
In countries such as Japan, South Korea, and France, sunscreens include newer chemical filters, some of which have been shown to provide broader protection against UV rays than those used in the U.S.
The Food and Drug Administration's ability to approve such ingredients is hamstrung by a 1938 U.S. law that has required sunscreens to be tested on animals and classified as drugs, rather than as cosmetics as they are in much of the world.
