Everything you wanted to know about sunscreen

From the Environmental Working Group's Sunscreen 2011 report.

Sunscreens Exposed

EWG’s 5th annual guide to safe and effective sunscreens features ratings for more than 1,700 sunscreens and SPF lip balms, moisturizers and makeups.

Highlights? Only one in five sunscreens earns high marks for safety and efficacy. Products with exaggerated SPF claims above 50 still crowd out better brands, and nearly one-third of this year’s crop of sunscreens contains vitamin A, an additive that can accelerate the growth of skin tumors and lesions.

Read EWG’s report to catch up on the science and politics behind the sunscreen industry and to learn how well this year’s products protect Americans’ skin from the sun’s damaging UV rays.
