When toxicologist Linda Birnbaum’s daughter was visiting recently, she asked to stop at a store to buy eye makeup. But when the salesperson began touting the benefits of a certain waterproof mascara, Birnbaum advised her daughter to steer clear.

Researchers recently found that waterproof, sweatproof and long-wearing cosmetics — so popular at this time of year — contain higher levels of a potentially toxic class of thousands of chemicals called perfluoroalkyl and polyfluoroalkyl substances or (PFAS).
