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 Lancôme.
- We flag Undisclosed waterproof polymer composition and potential VOC/fragrance content, Fragrance allergens and sensitization risk and Lash and eye irritation from incomplete removal or product buildup on the Lancôme and not on the Burt's Bees.
- The Burt's Bees is Wax, pigments, natural oils (typical mascara base) where the Lancôme is Undisclosed waterproof mascara formula with unknown coating, 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 Lancôme grade, at 35% 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 →
