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

Where these two actually differ

• We flag Fragrance allergens and sensitizers, Preservative residues (parabens or alternatives), Emulsifier and surfactant irritation and UV filter migration and degradation on the Australian Gold 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 Australian Gold.
• The Australian Gold is water-resistant emulsion lotion (aqueous base with potential hydrocarbon/silicone emulsifiers) 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 Australian Gold grade, at 35% confidence against 88%, because it discloses less.
