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 Clinique.
  • We flag Undisclosed waterproofing agents (likely fluorochemicals or silicones), Fragrance allergens and sensitizers and Microfiber shedding and eye irritation on the Clinique and not on the Burt's Bees.
  • The Burt's Bees is Wax, pigments, natural oils (typical mascara base) where the Clinique is Wax, film-forming polymers, waterproofing agents (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 Clinique 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 →
