Where these two actually differ

  • We flag Aluminum compound absorption and systemic exposure, Fragrance allergens and sensitizers and Irritation from aluminum salts on abraded or freshly shaved skin on the Carpe and not on the Primally Pure.
  • We flag Skin irritation from magnesium hydroxide alkalinity on the Primally Pure and not on the Carpe.
  • The Carpe is powder base, aluminum compounds where the Primally Pure is mineral-based powder blend (arrowroot, magnesium hydroxide, mica), 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 Primally Pure is the one to buy.
  • We are less certain about the Carpe grade, at 45% confidence against 82%, 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 →
