Where these two actually differ
- We flag Fragrance allergen sensitization on the Bare Minerals and not on the Charlotte Tilbury.
- We flag Fragrance allergens and undisclosed fragrance components on the Charlotte Tilbury and not on the Bare Minerals.
- The Bare Minerals is mineral powder, silicones, mica where the Charlotte Tilbury is liquid primer with silicones and pigments, 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 Charlotte Tilbury grade, at 45% 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 →
