Where these two actually differ
- We flag Fragrance allergen sensitization on the Bare Minerals and not on the L'Oréal.
- We flag 1,4-dioxane (potential trace contaminant), Formaldehyde-releasing preservatives, Heavy metals in colorants (if pigmented) and Fragrance allergens on the L'Oréal and not on the Bare Minerals.
- The Bare Minerals is mineral powder, silicones, mica where the L'Oréal is Water-based liquid primer, typical silicone and glycerin blend, 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.
