MAC Locked Kiss 24HR Lipstick
Skip until brand discloses waterproofing chemistry; waterproof cosmetics often use fluorinated polymers.
MAC's Locked Kiss 24HR is a waterproof long-wear lipstick. Waterproofing in cosmetics frequently relies on PFAS-based or Teflon-family coating coatings, yet MAC makes no public disclosure of ingredients or PFAS status. Without third-party testing or a brand commitment to PFAS-free formulation, risk remains unquantified.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 42% 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.
