A consumer group says that certain popular, U.S.-made red lipsticks contain "surprisingly high levels of lead" that might be potentially dangerous, and the Food and Drug Administration said it would investigate, while cautioning that previous claims "have not generally been supported" by FDA analysis, the Associated Press says.

The lead tests were conducted on 33 brand-name lipsticks by an independent laboratory last month on red lipsticks bought in Boston, San Francisco, Minneapolis and Hartford, Conn., according to the Campaign for Safe Cosmetics. The group, which advocates for toxic-free products, said that 61% had detectable levels of lead, and that one-third exceeded the FDA's lead limit of 0.1 ppm for candy. The FDA hasn't set a level for lipstick.

Here's the organization's press release and the full report.
