Since 1978 the Food and Drug Administration has been promising to provide sunscreen standards to help the public understand what they are buying and how well it will work (if at all). This hasn't happened though, so the Environmental Working Group has been taking matters into their own hands. They do an annual review of thousands of sunscreens to test their effectiveness and how many hazardous chemicals they contain. Their results are astounding.
3 of 5 brand-name sunscreens either don't protect skin from sun damage or contain hazardous chemicals – or both.
Only 1 in 10 sunscreens offer superior protection and safer ingredients (742 tested).
1 in 5 daily moisturizers let damaging UVA rays through (224 tested).
2 in 5 lip balms leaves lips vulnerable to sunburn, aging and cancer (153 tested).
59 sunscreens with SPFs from 55-100+ might tempt you to stay out longer in the sun, but they block just 1-2% more sunburn rays than an SPF 30 sunscreen.
Go out and repurchase your sunscreen, now.
