Lead and arsenic aren’t listed among the ingredients of lip gloss and eyeliner. However, Environmental Defence, a Canadian environmental group tested dozens of common cosmetics products and found that virtually all of them were contaminated with heavy metals.
Researchers purchased cosmetics in Toronto, and sent them to an accredited laboratory to have them tested for the presence of arsenic, cadmium, lead, mercury, beryllium, selenium, thallium and nickel. The items tested included foundations, concealers, powders, blushes, bronzers, mascaras, eyeliners, eyeshadows, lipsticks and glosses.
According to the Montreal Gazette:
“None of the products tested contained mercury, but lead was detected in 96 percent of the products, arsenic in 20 percent and cadmium in 51 percent. Nickel was found in all the products tested, beryllium in 90 percent, thallium in 61 percent and selenium in 14 percent.”
