Daily Sun Serum SPF 30 Mineral Sunscreen vs Ultimate Sun Protector Lotion SPF 60+: 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 irritants, Organic UV filter sensitization (oxybenzone, octinoxate, or similar) and 1,4-dioxane (byproduct of ethoxylated ingredients) on the Shiseido and not on the Derma E.
• The Derma E is Mineral sunscreen, zinc oxide base where the Shiseido is Water-resistant sunscreen lotion (likely silicone, polymers, UV filters), 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 45% confidence against 88%, because it discloses less.
