Summer Sunshine: What the FDA doesn't want you to know

John Stossel wrote a great article here about Mexoryl, a sunblock ingredient that helps block UVA rays. Most of the world uses this ingredient, coupled with others to effectively block out all harmful effects of sunlight. But the FDA has refused to approve it. It has even refused to explain why it isn't approving it for public use. So Americans can just get more wrinkly, I guess.
