Where these two actually differ
- We flag Skin irritation and contact dermatitis, Fragrance allergens and Roll-on applicator material degradation on the Certain Dri and not on the Primally Pure.
- We flag Skin irritation from magnesium hydroxide alkalinity on the Primally Pure and not on the Certain Dri.
- The Certain Dri is Aluminum oxide roll-on applicator head; liquid antiperspirant base (typical, aluminum chlorohydrate + alcohol + glycerin 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 25 points, wide enough that this is not a close call, and the Primally Pure is the one to buy.
