- Free shipping over the maker's published threshold
Kosas Chemistry is a serum-style deodorant rather than a solid stick. The maker describes it as clean and stain-free, built around a blend of alpha hydroxy acids (AHAs), and says it contains no aluminum and no baking soda. The page also claims it soothes and brightens skin and helps with ingrown hairs, which are the maker's cosmetic claims.
It is sold in several scents with separate identifiers per variant. Some variants of this line are marketed as fragrance-free, so do not assume the scent you pick matches that claim; read the ingredient list of the exact variant.
Acid-based formulas can sting on freshly shaved or irritated skin.
