Where these two actually differ
- We flag Fragrance allergens and undisclosed sensitizers and Bacterial growth and contamination in wax formula on the Burt's Bees and not on the NARS.
- We flag Undisclosed waterproof coating chemistry (possible fluorinated compounds) and Polymer film residue and eye irritation if not fully removed on the NARS and not on the Burt's Bees.
- The Burt's Bees is Wax, pigments, natural oils (typical mascara base) where the NARS is Wax, film-forming polymers, waterproof coating (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 Burt's Bees is the one to buy.
- We are less certain about the NARS grade, at 35% 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 →
