BECCA x Chrissy Teigen Glow Gloss vs Liquid Lipstick: which is safer?
BECCA x Chrissy Teigen Glow Gloss is the clear pick. Sigma Beauty Liquid Lipstick carries a failing PFAS grade, and we never recommend buying a failing product.

Where these two actually differ
- We flag Heavy metals in pigments (lead, cadmium, chromium), Formaldehyde releasers in preservative systems, 1,4-dioxane contamination (from ethoxylated emulsifiers) and Microplastic particle shedding during wear on the Sigma Beauty and not on the Becca Cosmetics.
- Both carry a flag for Fragrance allergens and undisclosed components, so neither choice avoids it.
- The Becca Cosmetics is Glycerin, silicones, pigments, film-formers (typical liquid cosmetic gloss) where the Sigma Beauty is liquid pigment blend, waterproofing agents unspecified, which is most of the difference in these two grades.
- The gap is 45 points, wide enough that this is not a close call, and the Becca Cosmetics is the one to buy.
- We are less certain about the Sigma Beauty grade, at 45% confidence against 78%, because it discloses less.
Both products run through the same public rubric, which covers materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
