More than half the cosmetics sold in the United States and Canada likely contain high levels of a toxic industrial compound linked to serious health conditions, including cancer and reduced birth weight, according to a new study.

Researchers at the University of Notre Dame tested more than 230 commonly used cosmetics and found that 56% of foundations and eye products, 48% of lip products and 47% of mascaras contained high levels of fluorine—an indicator of PFAS, so-called "forever chemicals" that are used in nonstick frying pans, rugs and countless other consumer products.
