Where these two actually differ
- We flag Fragrance allergen sensitization on the Bare Minerals and not on the Lancôme.
- We flag Fragrance allergens and sensitizers and 1,4-dioxane (indirect contaminant) on the Lancôme and not on the Bare Minerals.
- The Bare Minerals is mineral powder, silicones, mica where the Lancôme is silicone polymer base, standard cosmetic emollients, 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 Lancôme grade, at 45% confidence against 72%, because it discloses less.
