Where these two actually differ
- We flag Undisclosed waterproofing agent (PFAS risk) and Coating degradation and microparticle shedding on the Anastasia Beverly Hills and not on the L'Oréal.
- We flag 1,4-dioxane contamination from emulsifiers, Fragrance allergens (unlisted components) and Microbial growth if stored improperly on the L'Oréal and not on the Anastasia Beverly Hills.
- The Anastasia Beverly Hills is Wax/pigment blend with waterproof coating, composition unspecified where the L'Oréal is water, hyaluronic acid, glycerin, pigments, emollients, 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 L'Oréal is the one to buy.
- We are less certain about the Anastasia Beverly Hills grade, at 35% confidence against 75%, 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 →
