Lipstick can give your lips color, sheen and texture, but may also put you at risk of ingesting potentially toxic metals, UC Berkeley researchers say in the latest study to ferret out questionable compounds in cosmetics. The scientists said [on May 2 that] they found metals in every one of the 32 lipsticks and lip glosses they tested. Some of those substances, including lead, cadmium and chromium, are banned from cosmetics in Europe, but not in the United States. Previous studies had detected traces of lead in lipstick, but the researchers said theirs was the first to find a variety of other metals that can be toxic in high doses. Manganese, for example, which was found in varying amounts in the tested products, is linked to neurological defects in humans who inhale it on a continuous basis. Makeup manufacturers in the United States sometimes use metals as color additives. The researchers believe that potentially harmful metals are present in possibly thousands of lip products beyond the 32 they tested. The fact that virtually all of them have some metals of some concern leads me to say that it's a concern in general," said Katharine Hammond, a UC Berkeley environmental health sciences professor and the study's primary investigator. The report appears in the current issue of Environmental Health Perspectives. Consumers should not be burdened with figuring out which products are safe, [Hammond] argued. Instead, she said, the responsibility belongs to the U.S. Food and Drug Administration, which regulates cosmetics.
