The EWG's 2009 Sunscreen Guide
Unfortunately, the sunscreen you’re using on yourself or your children may not actually work. The Environmental Working Group’s report for 2009 explains:
3 of 5 brand-name sunscreens either don’t protect skin from sun damage or contain hazardous chemicals — or both.
Here in Florida, where it’s Summer for 364 days a year, sunscreen is of critical importance. My wife researched this issue right after the boy was born, and we wound up switching to completely new and heretofore unheard of (and expensive) sunscreens recommended by the EWG. They actually work (we noticed a big difference), and they don’t breakdown after application.
