Where these two actually differ
- We flag Fragrance allergen sensitization on the Bare Minerals and not on the MAC.
- We flag Fragrance allergens and 1,4-dioxane (solvent contaminant) on the MAC and not on the Bare Minerals.
- The Bare Minerals is mineral powder, silicones, mica where the MAC is silicones, oils, pigments, mineral-based powders, 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.
