PFAS Forever Chemicals Detected in Some Period Products and Cosmetics

Toxic "forever chemicals" known as PFAS have been detected in feminine hygiene products like Thinx menstrual underwear and pads. PFAS exposure has been linked to cancer and other illnesses.

Multiple studies have confirmed the presence of PFAS in period products. Thinx settled a lawsuit over PFAS allegations in its underwear but denies its products contain the chemicals.

PFAS are also common in cosmetics, with a study finding high levels of fluorine indicating PFAS in 63% of foundations, 58% of eye products, 55% of lip products and 47% of mascaras tested.

Workout leggings and yoga pants from major brands allegedly contain PFAS as well, according to testing by a third-party EPA-certified lab.

PFAS absorption through skin contact is not well researched but concerning. Women tend to use more PFAS-containing personal care products, raising their exposure.
