Where these two actually differ
- We flag Fragrance allergen sensitization on the Bare Minerals and not on the Charlotte Tilbury.
- We flag Heavy metals in mineral pigments, Fragrance allergens (undisclosed components), 1,4-dioxane (process contaminant) and Preservative allergens or irritants on the Charlotte Tilbury and not on the Bare Minerals.
- The Bare Minerals is mineral powder, silicones, mica where the Charlotte Tilbury is silicone, glycerin, mineral pigments, which is most of the difference in these two grades.
- The gap is 25 points, wide enough that this is not a close call, and the Bare Minerals is the one to buy.
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 →
