In a new study, pregnant and breastfeeding women who used personal care products like nail polish, makeup and hair dyes had significantly higher levels of toxic chemicals called PFAS in their blood plasma and breast milk.

Researchers detect 10 PFAS chemicals in tap and bottled water samples collected from 15 countries.

Girls exposed to certain endocrine-disrupting chemicals are more likely to start puberty early – increasing their risk for obesity, diabetes and heart disease, researchers say.

A new study links parabens and phenols used in many makeup and sunscreen products to high blood pressure in pregnant women.
