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 Kiehl's.
- We flag Fragrance allergens, Chemical UV filter photostability and skin absorption and Preservative system irritation on the Kiehl's and not on the Derma E.
- The Derma E is Mineral sunscreen, zinc oxide base where the Kiehl's is Water-based UV serum with humectants and 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.
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 →
