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 Fragrance allergens or undisclosed fragrance chemicals and Bacterial or fungal contamination from repeated wand contact 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 mascara pigments, waxes, resins, film-forming polymers, which is most of the difference in these two grades.
- We are less certain about the NARS grade, at 45% confidence against 78%, because it discloses less.
Both products run through the same public rubric: 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 →
