4 out of 5 of the nearly 1,000 sunscreen lotions analyzed offer
inadequate protection from the sun or contain harmful chemicals. The
biggest offenders, the EWG said, are the industry leaders: Coppertone,
Banana Boat and Neutrogena... Sunscreens do not offer blanket
protection from the sun and do little to prevent the most deadly form
of skin cancer; reliance on them instead of, say, a hat and protective
clothing, might be contributing to skin cancer... Almost all sunscreen
lotions contain chemicals that, perhaps counter-intuitively, breakdown
in the presence of sunlight. But in fact this is how they block UVB
from penetrating the skin, like a castle wall protecting against
cannonballs until the wall crumbles. Notions of all-day protection, as
some sunscreen products claim, or even several hours of protection are
ludicrous, the EWG said, because most sunscreens start deteriorating
in as quickly as 15 minutes. This doesn't even account for sweat and
casual rubbing, further reducing protection. source:
