The FDA finds lead in 400 shades of lipstick.

There is no immediate concern as the effects of lead poisoning are cumulative.

In a letter to the FDA last week, the Campaign for Safe Cosmetics countered that “lead builds up in the body over time and lead-containing lipstick applied several times a day, every day, can add up to significant exposure levels” — a particular concern for millions of women of childbearing age, the group said. Citing a recent report by the Centers for Disease Control and Prevention stating that no amount of lead is safe for children and that exposure in both children and pregnant women should be prevented, the group pushed the FDA again to set a maximum allowable limit for lead in cosmetics.
