RMS Beauty Legendary Serum Lipstick | Red | One Size | Shopbop
Lower concern; RMS Beauty's natural lipstick formula is unlikely to contain PFAS, but no public testing exists.
RMS Beauty markets this product as a serum lipstick made with natural waxes and plant oils, which typically do not require PFAS-based water/stain repellency. The brand does not disclose PFAS testing or make PFAS-free claims.

The full breakdown
What it's made of and why it matters
RMS Beauty Legendary Serum Lipstick uses a cream lipstick base of plant-derived waxes (typically candelilla or beeswax) and botanical oils rather than synthetic silicones or polymers common in conventional lipsticks. This formulation avoids Teflon-type coating/Teflon-family coating coatings and reduces exposure to volatile organic compounds (VOCs) that off-gas from petroleum-based emollients. Pigmentation relies on iron oxides and mica, which are inert mineral colorants with minimal systemic toxicity risk from topical application.
The brand's record and disclosure
RMS Beauty markets itself as a clean beauty brand emphasizing natural and organic ingredients; the company does not publicly disclose PFAS testing or certification but avoids synthetic polymer systems that typically harbor PFAS. The brand holds no major product recalls or regulatory warnings on record. Transparency on ingredient sourcing is present on product pages, though independent third-party testing data is not publicly available.
How it compares in its category
Cream lipsticks with wax-oil bases (like RMS) generally carry lower chemical hazard profiles than glosses or long-wear formulas, which often contain silicones, film-forming resins, and plasticizers. Compared to conventional brands, RMS avoids azo dyes and synthetic fragrance compounds that can pose allergen risks. The trade-off is slightly lower color payoff and longevity versus synthetic alternatives.
If you buy it
Store in a cool location away from direct sunlight to prevent oil separation and oxidation, which can degrade the formula over time. Do not expose to temperatures above 80°F for extended periods, as wax-based lipsticks can soften and lose shape. Replace after 12-18 months or if the texture becomes grainy or emits an off odor. Patch test on lips before full application if you have a history of fragrance or botanical oil sensitivity.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Heavy metals in iron oxide pigments
Iron oxides used in natural lipsticks are generally recognized as safe colorants by regulatory bodies; no contamination incidents reported for RMS Beauty products.
Fragrance allergens in botanical oil blends
RMS Beauty lipsticks contain essential oils and plant extracts that may trigger contact dermatitis or perioral irritation in sensitive individuals; brand does not list fragrance components in detail.
Microbial contamination from natural preservatives
Wax-oil formulas with minimal synthetic preservatives may have lower inherent antimicrobial stability; no recalls or contamination reports exist for this brand.
Lead or cadmium in mica or colorant contaminants
Mica and iron oxide suppliers in the cosmetics industry are routinely tested; no heavy metal alerts on record for RMS Beauty formulations.
Oxidative degradation of botanical oils over time
Plant oils in the formula can oxidize and produce free radicals or off-odors with age or heat exposure; proper storage mitigates this risk.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% 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.
