Some detoxers who stopped using the traditional deodorants and antiperspirants secreted a bacteria called staphylococcus hominis, which makes the armpits smell, while non-deodorant users secreted a bacteria called Corynebacterium, which doesn’t smell as much. Armpit detoxification is a personal choice, so as long as you wash under your arms to get rid of residue, you’ll have healthy armpits.
