Where these two actually differ

  • We flag Fragrance allergen sensitization on the Bare Minerals and not on the Smashbox.
  • We flag Fragrance allergen load and Silicone buildup on skin on the Smashbox and not on the Bare Minerals.
  • The Bare Minerals is mineral powder, silicones, mica where the Smashbox is silicone, water-resistant emollient blend, which is most of the difference in these two grades.
  • The gap is 70 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 Smashbox grade, at 45% confidence against 72%, because it discloses less.

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 →
