Sport SPF 50 Sunscreen Lotion vs Daily Sun Serum SPF 30 Mineral Sunscreen: which is safer?

Where these two actually differ

• We flag Fragrance allergens and sensitizers, Organic UV filter photostability concerns, Preservative-related sensitization and Octocrylene or related UV filter systemic absorption on the Banana Boat and not on the Derma E.
• 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 Banana Boat.
• The Banana Boat is Oil-in-water emulsion with waterproofing agents where the Derma E is Mineral sunscreen, zinc oxide 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 Banana Boat grade, at 42% confidence against 88%, because it discloses less.
