PFAS in Cosmetics (“Forever Chemicals”) 💄🧴⚠️
GodFit is back with another ingredient to watch for, this time in makeup + personal care.
PFAS (per- and polyfluoroalkyl substances) are a large group of chemicals sometimes used in cosmetics to help create water resistance, smooth application, and long-wear performance.
Here’s why this matters:
• Some PFAS have been linked to health concerns.
• PFOA, one specific PFAS, was evaluated by the WHO cancer agency (IARC) as carcinogenic to humans (Group 1), with limited evidence in humans for testicular and kidney cancer.
• U.S. public health summaries (CDC/ATSDR) also note associations for PFOA that include kidney and testicular cancer (risk depends on exposure).
Where PFAS may hide (common product types):
✅ Waterproof mascara + eyeliner
✅ Long-wear foundation / concealer
✅ Lip products
✅ Primers + setting powders
(Products marketed as “waterproof,” “long-lasting,” or “all-day wear” are common places to check.)
What to look for on ingredient lists:
• PTFE
• Perfluorononyl dimethicone
• Ingredients containing “perfluoro-” or “polyfluoro-”
GodFit’s reminder: always check the label, because formulas change.
