 More than half of the sunscreens on the market do not provide adequate UVA protection, and many of them actually contain hazardous ingredients, according to an analysis of 292 national brands and 1,700 products by the nonprofit Environmental Working Group, based in Washington.

The problem, the group's researchers said, is that the sunscreen industry has taken advantage of lax federal regulations and allowed a marketing Wild West to develop. Many products with high sun-protection factor, or SPF, ratings contain bad ingredients, and companies use unsubstantiated claims about their effectiveness to market them, the group said.
