Stila Stay All Day Chroma- Flash Liquid Eye Liner
Moderate concern: waterproof liquid cosmetics often use PFAS-containing resins; Stila discloses nothing.
Stila's Stay All Day eyeliner is formulated for waterproof, long-wear performance, properties historically achieved with fluorinated polymers or PFAS-based film-formers in liquid cosmetics. Stila has made no public PFAS disclosure or third-party verification.

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.
