The Short Answer
Yes, makeup is a major hidden source of PFAS exposure. These synthetic "forever chemicals" are frequently added to cosmetics to make them waterproof, sweat-resistant, and incredibly smooth to apply.
The numbers from a landmark University of Notre Dame study are staggering: researchers found high levels of fluorine—a strong indicator of PFAS—in 52% of the products they tested. Waterproof mascara is the worst offender, with an 82% failure rate, followed closely by liquid foundations and lipsticks.
Why This Matters
PFAS do not break down in the human body or the environment. Once absorbed, these chemicals accumulate in your blood and organs over time. They are firmly linked to immune suppression, developmental issues, and an increased risk of certain cancers.
Your face is a highly vulnerable route for chemical exposure. While general skin absorption varies, applying PFAS directly to your tear ducts via eyeliner, or swallowing it through liquid lipsticks, guarantees these chemicals enter your system. Is There Lead In Lipstick
The federal government still doesn't restrict PFAS in cosmetics. While the Modernization of Cosmetics Regulation Act (MoCRA) forced the FDA to assess the issue, there is still no nationwide ban keeping these chemicals out of your makeup bag. Is Makeup Regulated For Safety In The Us
States are finally taking matters into their own hands. Strict bans on PFAS in cosmetics took effect in California, Washington, and Minnesota in 2025, with Vermont and Maine following in 2026. However, non-compliant older stock still floods the shelves in unregulated states.
What's Actually In Waterproof Makeup
If you look closely at ingredient lists, you'll rarely see the acronym "PFAS." Manufacturers hide these forever chemicals behind complex chemical names. What Ingredients Should You Avoid In Makeup
- PTFE (Polytetrafluoroethylene) — This is literally Teflon. It's the exact same non-stick chemical used on frying pans, added to cosmetics to create a frictionless finish.
- Perfluorooctyl Triethoxysilane — Used to treat pigments and make makeup long-lasting. It repels both oil and water, which is why your "24-hour" foundation doesn't sweat off.
- Perfluorononyl Dimethicone — A silicone-fluorocarbon hybrid. It's heavily used in liquid formulas to provide a slick texture and temporary skin-smoothing effect.
What to Look For
Green Flags:
- Third-Party Certifications — Look for MADE SAFE or EWG Verified seals. These organizations strictly prohibit the use of any fluorinated chemicals.
- Clean Brand Commitments — Buy from brands that publicly ban PFAS. Companies that actively test their supply chains for cross-contamination are your safest bet.
- Mineral-Based Formulas — Simple, raw ingredients reduce your risk. Powder cosmetics and oil-based tints rarely require synthetic waterproofing agents.
Red Flags:
- "Waterproof" Claims — This is the biggest warning sign. If a mascara or eyeliner requires intense scrubbing to remove, it likely relies on fluorinated chemicals or heavy silicones.
- "24-Hour" or "Smudge-Proof" — Long-wear claims usually require synthetic chemical assistance. Liquid lipsticks that dry down and never budge are notorious for containing PFAS.
- The Prefix "Fluoro" — Any ingredient containing "fluoro" or "perfluoro" is a PFAS. Scan the label carefully, though remember that half of cosmetics with PFAS don't disclose it on the label at all.

The Bottom Line
1. Ditch the waterproof formulas. Opt for water-resistant or tubing mascaras instead, which wash off easily and don't require toxic forever chemicals.
2. Check the label for "fluoro." Avoid anything with PTFE, perfluorodecalin, or any ingredient containing the "fluoro" prefix.
3. Shop for certified clean brands. Because PFAS can hide as undisclosed manufacturing byproducts, your best defense is buying from brands with third-party verification like MADE SAFE.
FAQ
Can PFAS be absorbed through the skin?
Yes, especially in sensitive areas like the eyes and lips. While intact skin provides some barrier, applying PFAS to the waterline, tear ducts, and mouth dramatically increases your internal exposure.
Why do companies put PFAS in makeup?
It makes cosmetics perform better under stress. PFAS repel both oil and water, making them the perfect chemical shortcut for creating smudge-proof, sweat-resistant, and ultra-smooth makeup.
Are PFAS in makeup banned in the US?
There is no federal ban, but state laws are actively changing the market. States like California, Washington, and Minnesota enacted strict bans in 2025, with more states following in 2026, forcing many brands to finally reformulate.
