Daily Sun Serum SPF 30 Mineral Sunscreen vs Daily Suncare Set: which is safer?

Where these two actually differ

• We flag 1,4-dioxane (non-intentional contaminant from surfactants/emulsifiers) and Fragrance allergens (if fragrance is present) on the Derma E and not on the Shiseido.
• We flag Fragrance allergens and sensitizers, 1,4-dioxane (byproduct in surfactants/emulsifiers) and Photochemical instability or UV filter degradation on the Shiseido and not on the Derma E.
• The Derma E is Mineral sunscreen, zinc oxide base where the Shiseido is water-resistant cosmetic formulation (likely silicone/mineral base), 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 Derma E is the one to buy.
• We are less certain about the Shiseido grade, at 35% confidence against 88%, because it discloses less.
