BECCA x Chrissy Teigen Glow Gloss vs Le Rouge Duo Ultra Tenue Liquid Lip Colour: which is safer?

BECCA x Chrissy Teigen Glow Gloss is the clear pick. Chanel Le Rouge Duo Ultra Tenue Liquid Lip Colour carries a failing PFAS grade, and we never recommend buying a failing product.

Where these two actually differ

  • We flag Fragrance allergens and undisclosed components on the Becca Cosmetics and not on the Chanel.
  • We flag Heavy metals in synthetic pigments (iron oxides, titanium dioxide, carmine), Fragrance allergens and undisclosed fragrance components, Film-forming polymer toxicity and irritation and Waterproof topcoat composition unknown (likely PFAS-containing) on the Chanel and not on the Becca Cosmetics.
  • The Becca Cosmetics is Glycerin, silicones, pigments, film-formers (typical liquid cosmetic gloss) where the Chanel is liquid pigment suspension with film-forming polymers, waterproof topcoat, 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 Chanel grade, at 42% 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 →
