Where these two actually differ
- We flag Heavy metals in mineral pigments (lead, cadmium, chromium), Fragrance allergens and skin irritation and Bismuth oxychloride sensitivity on the Bare Minerals and not on the MAC.
- We flag Fragrance allergens and undisclosed ingredients and PFAS in water-resistant or film-forming claims on the MAC and not on the Bare Minerals.
- 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 MAC grade, at 35% confidence against 100%, 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 →
