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 Titanium dioxide nanoparticle inhalation, Skin irritation or photosensitivity from mineral filters, Fragrance allergens or irritant additives and Emulsifier or preservative sensitization on the Shiseido and not on the Derma E.
- The Derma E is Mineral sunscreen, zinc oxide base where the Shiseido is Mineral UV filters (zinc oxide, titanium dioxide), lotion emulsion 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.
Both products run through the same public rubric, which covers materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
