Daily Sun Serum SPF 30 Mineral Sunscreen vs SPF Lotion Sunscreen: 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 Sun Bum Original.
• We flag Fragrance allergens and contact sensitizers, Preservative sensitivity (methylisothiazolinone, paraben-class, or phenoxyethanol), Organic UV filter photostability and skin penetration and Lotion base stability under heat or light on the Sun Bum Original and not on the Derma E.
• The Derma E is Mineral sunscreen, zinc oxide base where the Sun Bum Original is Oil/water emulsion lotion base with waterproofing actives, 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 Sun Bum Original grade, at 55% confidence against 88%, because it discloses less.
