Try this site, it rates various brands of sunscreen for their safety http://www.cosmeticsdatabase.com/spe...php?nothanks=1

I tried the brand that's #1 on their safety list, but it gave me horrible pimples, smelled awful, and offered no water repellency (a must since I swim outdoors).

So now I'm going to try this one, which is also reef safe (a recent study is pointing to the ingredients in sunscreen as one of the primary reasons for reef die-offs).
