More than half of popular cosmetics being sold in the US and Canada are likely to contain high levels of toxic chemicals called polyfluoroalkyl substances (PFAS), a new study has warned.
Researchers from Notre Dame University tested more than 200 products including concealers, foundations, eye and eyebrow products and lip products, and found evidence of PFAS in around half (52 per cent) of them.
Worryingly, previous research has linked certain PFAS to a range of health issues, including kidney cancer, testicular cancer, hypertension, thyroid disease, low birth weight and immunotoxicity in children.
