A small study of store-bought lipstick suggests the makeup may be doing more than giving the appearance of plump, shiny lips -- it could be increasing your exposure to toxic metals.
researchers at the university of california berkeley tested over thirty different lipsticks and lip glosses, looking at the amount of metal each contained -- like lead, cadmium, chromium and aluminum.
they also researched health guidelines to learn what is considered a "safe" amount of intake for each of the metals.
they found average use of lipstick could increase the amount of chromium in the blood -- which has been linked to stomach tumors.
however, they say most adults should not experience harm from lipstick -- but it should be kept away from children.
