Where these two actually differ
- We flag Fragrance allergen sensitization on the Bare Minerals and not on the Laura Mercier.
- We flag Fragrance allergens and 1,4-dioxane (solvent contaminant) on the Laura Mercier and not on the Bare Minerals.
- The Bare Minerals is mineral powder, silicones, mica where the Laura Mercier is silicone polymers, dimethicone, proprietary film-forming agents, which is most of the difference in these two grades.
- The gap is 60 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 Laura Mercier 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 →
