Armpit-microbiome probiotic formulation

Deodorants that use probiotic bacterial strains or fermentation-derived ingredients to manage odor-causing armpit bacteria at the source, rather than masking odor or blocking sweat with aluminum salts — a genuine bio-mechanism distinct from the much larger 'natural/clean' deodorant market, where most products are simply aluminum-free reformulations with no biological mechanism claim — sold by four specialists (Fussy, Sagittamed, By Robin Creations, AIMU) spanning finished consumer brands and an OEM manufacturer.
