Daily Sun Serum SPF 30 Mineral Sunscreen vs Slip Tint Dewy Tinted Moisturizer SPF 35: which is safer?
Daily Sun Serum SPF 30 Mineral Sunscreen is the clear pick. Slip Tint Dewy Tinted Moisturizer SPF 35 carries a failing PFAS grade, and we never recommend buying a failing product.

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 Saie.
- We flag 1,4-dioxane (manufacturing byproduct), Heavy metals in color pigments (iron oxides, mica) and UV filter photostability and breakdown products on the Saie and not on the Derma E.
- The Derma E is Mineral sunscreen, zinc oxide base where the Saie is cosmetic emulsion, likely glycerin, water, silicones, which is most of the difference in these two grades.
- The gap is 35 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 Saie grade, at 45% confidence against 88%, because it discloses less.
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 →
