Previously I wrote about finding a healthier natural spf sunscreen and I found a better link to EWGEWG Environmental Working Group - an organization focused on research to make informed choices and live a healthy life in a healthy environment.’s 2013 Natural SPF Sunscreens. It’s an excellent resource:

As well as an iphone app if you want detailed info on the go (maybe you’re flying somewhere, only taking a carry-on and can’t take more than 3oz of sunscreen with you…)
