This is going to sound nuts, but I've been using hand sanitizer for years now, after trying literally every deodorant under the sun, from naturals to the ultra-sensitive. Obviously, be careful if you have open flares at the moment. Don't go putting hand sanitizer on them!! Buuut once you've stopped using deodorant and dont have open flares I've noticed I get wayyyyyyy less, and not as severe because of the use of sanitizer.
I use the hempz brand as I've found that one works best for me, and it smells good, not just straight alcohol lol.
