Where these two actually differ
- We flag AHA irritation and skin barrier disruption on the Kosas and not on the Puracy.
- We flag Fragrance allergens, Formaldehyde releasers and Glass container breakage on the Puracy and not on the Kosas.
- The Kosas is aqueous cream serum and powder deodorant base where the Puracy is Glass jar; water-based cream formula, 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 Puracy is the one to buy.
Both products run through the same public rubric: 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 →
