Where these two actually differ
- We flag Fragrance allergen sensitization on the Bare Minerals and not on the Revlon.
- We flag Fragrance allergens and sensitizers, Formaldehyde releasers in preservatives and Skin sensitization or irritation from film-former polymers on the Revlon and not on the Bare Minerals.
- The Bare Minerals is mineral powder, silicones, mica where the Revlon is silicone-based primer with polymeric film-formers, which is most of the difference in these two grades.
- The gap is 35 points, wide enough that this is not a close call, and the Bare Minerals is the one to buy.
- We are less certain about the Revlon grade, at 35% confidence against 72%, 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 →
