Makeup marketed as wear-resistant or long-lasting often contains synthetic chemicals that could pose a risk to human health and the environment, a new study co-authored by the University of Toronto's Miriam Diamond suggests. 

Diamond, a professor in the department of Earth sciences in the Faculty of Arts & Science, and her colleagues studied 231 cosmetic products and found the highest concentration of polyfluoroalkyl substances (PFAs), a potentially toxic class of chemicals, in foundations, mascaras and lip products 鈥 especially those that were labelled 鈥渨ear-resistant,鈥 鈥渓ong-lasting鈥 or 鈥渨aterproof.鈥

鈥淲hat's really concerning about them is that they're highly persistent,鈥 . "It'll stick around for years, actually. 鈥 Decades."

Scientists often refer to PFAs as 鈥渇orever chemicals鈥 because they can linger in the body for so long. They have also been linked to negative health effects such as increased cancer risk, decreased immune response and decreased fertility, according to the CBC.

The research  in the journal Environmental Science & Technology Letters.

鈥淲e can鈥檛 afford to contaminate our drinking water as well as our bodies,鈥 Diamond . 鈥淚s your beauty worth taking a risk with your health?鈥
