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 Fragrance allergens and undisclosed fragrance chemicals, Preservative-related irritation (parabens, phenoxyethanol, etc.), Organic UV filter photostability and skin absorption and Emulsion separation and microbial growth if stored improperly on the Isdin and not on the Derma E.
  • The Derma E is Mineral sunscreen, zinc oxide base where the Isdin is typical cosmetic emulsion/cream base (water, glycerin, oils, emulsifiers), 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 →
