Is there anything that actually prevents armpit sweat?
Solutions to managing armpit sweat and odor: 1) Shave your armpits once every few months to periodically clear out that persistent bacteria. 2) Sprits or dampen armpits with diluted alcohol solution to kill the bacteria (don’t do this immediately after shaving). 3) Apply adhesive armpit pads to your favorite shirts, so as to prevent bacteria and deodorant buildup in them. 4) Consult with your doctor before doing any of these, except #3.
