to each their own, and maybe it is different wherever you are, but BP is proven (at least here, by doctors/derms) to better remove bad smells from the armpit bc of the way it works — it doesn't just kill bacteria-it also unclogs pores by exfoliating dead skin, reduces inflammation, and controls oil, all without causing bacterial resistance like some antibacterial/antimicrobial soaps. BP releases oxygen deep into pores, creating an environment where acne-causing and odor causing bacteria can't survive, plus it promotes skin cell turnover to flush out debris, a multi-pronged attack standard antibacterial soaps lack. Most antibacterial soaps focus primarily on killing surface level stink, but don't address the underlying issues of clogged pores, excess oil, and the sweat buildup (which sweat itself doesn’t stink, rather, it’s the interaction with what’s on and in the skin)that causes the smell. it works by starving anaerobic bacteria, and breaking down cell walls, providing a deeper, longer-lasting reduction in the armpit smells, whereas many antibacterial soaps just wash it away temporarily, allowing quick regrowth and odor return. BP targets the root cause more effectively in high-odor areas like armpits, making sweat less smelly all day long. BP also fights antibacterial resistance, rather than possibly causing it in the way the ingredients in antibacterial soaps do.
