Where these two actually differ
- 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 NARS.
- We flag Heavy metals in pigments (iron oxide, synthetic colorants, mica), Fragrance allergens and 1,4-dioxane in emulsifiers or surfactants on the NARS and not on the L'Oréal.
- The L'Oréal is water, hyaluronic acid, glycerin, pigments, emollients where the NARS is liquid foundation, pigments, emollients, binders, which is most of the difference in these two grades.
- We are less certain about the NARS grade, at 40% 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 →
