"PFAS-Free"

A peer-reviewed study from Notre Dame, Toronto, and the Green Science Institute found over half of tested cosmetics contained fluorine — a strong indicator of PFAS presence — with waterproof mascara, liquid lipstick, and foundation showing the highest levels. Independent testing by Mamavation found organic fluorine indicators in 54 of 83 lip and eye products, including ones marketed as clean. Standard EPA PFAS detection methods were validated for drinking water, not cosmetic matrices, producing dangerous false negatives.
