curious about sunscreen?

I've been thinking a lot about chemicals and providers and all that jazz, and sometimes it makes me downright anxious when anticipating purchasing something . . . like sunscreen. Which company is the best, what are they really putting in there, do i even have access to worthwhile products?! Sometimes it's a little overwhelming - BUT, fortunately there are people out there with more information than myself. This article sat in my email inbox for weeks . . . maybe months. But I finally whipped it out (or clicked on the link) and it was very interesting and useful. Anyhow, I figured I would put it up here so that if ever I need to find it again, I'll know where to look.
