The Food and Drug Administration logged 144 complaints about cosmetics in 2003, and it continues to investigate questions about the safety of thousands of products. However, the agency can't require safety testing or make companies disclose what's in their products without taking them to court.
Meanwhile, the environmental working group says it has looked at 7,500 beauty products. It claims 99% contain at least one ingredient that has not been tested and it says a third contain "known or possible carcinogens."
"People shouldn't throw out their handbags full of cosmetics from their medicine cabinet. But they should be aware that most of these chemicals haven't been tested for safety," says Tim Kropp, with the Environmental Working Group.
In response to claims from the Environmental Working Group, the FDA sent a letter to the cosmetic industry saying it is cracking down on warning labels. You can check safety scores for specific products on the Environmental Working Group by clicking here.
