PFAS score
NARS · Waterproof Mascara
Nars Light Flexible Formula with Intense Black Color Non-clumping and Smudge-Free Mascara Passi.4096
Skip or request PFAS disclosure; waterproof mascara warrants caution without transparency.
Nars does not publicly disclose PFAS content for this waterproof mascara. The 'smudge-free' and 'water-resistant' claims suggest a durable film coating, a common use case for PFAS in cosmetics, but the brand provides no ingredient list or PFAS statement. No third-party testing or certification backing this product is available.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
Safer alternatives in Waterproof Mascara

⚠Risky category by default
RMS Beauty
Volumizing Mascara
Wax, resin, and pigment base (typical mascara formulation)
Lower concern; standard mascara formula unlikely to contain PFAS, but brand makes no explicit commitment.
⚠Risky category by default
Tarte
Travel-size Tartelette
Powdered eyeshadow palette with talc or mica base
Lower concern for PFAS, powder cosmetics rarely need Teflon-family coating, but Tarte makes no public PFAS disclosure.
