Daily Sun Serum SPF 30 Mineral Sunscreen vs Fotoultra 100 Active Unify Color Spf 50+ 50ml: 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 Isdin.
• We flag Talc or iron oxide pigment contamination (heavy metals, asbestos risk in talc), Fragrance allergens and sensitizers, Silicone or acrylate polymer skin occlusion and comedogenicity and Preservative or antioxidant stability (oxidation byproducts over time) on the Isdin and not on the Derma E.
• The Derma E is Mineral sunscreen, zinc oxide base where the Isdin is water-resistant emulsion (sunscreen); likely silicone or polymer-based water-resistance vehicle, 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 Isdin grade, at 45% confidence against 88%, because it discloses less.
