What Sigma Beauty Liquid Lipstick is made of, ingredients and materials
Sigma Beauty Liquid Lipstick is a pigment suspension in a polymer-resin base with unspecified waterproofing agents, likely acrylates or similar film-formers. Waterproof cosmetics commonly rely on PFAS-based water repellents to maintain wear; Sigma has not publicly disclosed their waterproofing chemistry, leaving uncertainty about PFAS content. The liquid format means pigments and preservatives must remain stable and suspended over months of shelf life, requiring careful formulation to avoid separation or microbial growth.
What’s concerning
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.

No PFAS disclosure
No public statement from the brand about PFAS in this product.
Lead
Cosmetic-grade iron oxides and synthetic colorants used in lipsticks are not routinely tested for heavy-metal contamination by all manufacturers. Sigma does not publish metal-testing data; PFDA color additives are regulated but not exhaustively tested for trace contamination at manufacturing.
Source, ATSDR ↗Formaldehyde / VOCs
Liquid lipsticks commonly use formaldehyde releasers (e.g., DMDM hydantoin, imidazolidinyl urea) to prevent microbial growth; Sigma's ingredient list does not disclose the specific preservative system, so exposure risk cannot be ruled out.
Source, ATSDR ↗Fragrance allergens and undisclosed components
Sigma Beauty liquid lipsticks are fragranced; fragrance is a known skin sensitizer and allergen source, but individual fragrance components are not disclosed (IFRA trade secret allowance). Individuals with fragrance sensitivity or atopic dermatitis face elevated risk.
1,4-dioxane contamination (from ethoxylated emulsifiers)
Acrylate-based waterproofing agents often require ethoxylated emulsifiers to stabilize the polymer-pigment suspension; these can carry 1,4-dioxane as a manufacturing byproduct. Sigma does not disclose emulsifier sourcing or distillation practices.
Microplastic particle shedding during wear
Liquid lipsticks shed polymeric film particles as they wear and flake; ingestion of these particles during eating or drinking is unavoidable. No specific data exists for Sigma products, but the polymer-based formula structure makes shedding a material concern over repeated daily use.
How is this PFAS grade calculated?
The brand's record and disclosure
Sigma Beauty has not published ingredient sourcing transparency, PFAS avoidance commitments, or safety certifications (e.g., COSMOS, Leaping Bunny). No major product recalls specific to this lipstick line are on public record. The brand markets to makeup artists and consumers but does not disclose preservative systems, pigment suppliers, or heavy-metal testing protocols, which limits independent verification of safety compliance.
How it compares in its category
Liquid lipsticks are inherently higher-risk for PFAS exposure because waterproofing is a core marketing feature; brands like MAC Fix+ or Fenty Beauty also do not disclose PFAS status. Sigma's lack of third-party certification (unlike some indie brands pursuing clean-beauty labeling) places it in the middle of the transparency spectrum. Compared to traditional cream or bullet lipsticks, liquid formulas require more aggressive preservation and film-forming chemistry, increasing complexity and potential exposures.
If you buy it
Apply only to lips; avoid ingestion and contact with eyes and mucous membranes. Do not use if you have a history of contact dermatitis or sensitivity to acrylates or fragrance. Replace every 12-18 months or if the formula separates, thickens, or develops odor, as preservative breakdown can increase bacterial contamination risk. Store in a cool, dry place away from direct sunlight to slow oxidation and preserve the waterproofing layer.
