Drysol
"I've have trouble with under arm sweat for years which has made me extremely self conscious and ruined many shirts. A friend suggested Drysol after having great results, so I asked my doctor if I could give it a try. My underarm sweat diminished probably 80% after the first use and seems nonexistent now after two applications. I use a very small amount, dry my underarms with the no heat setting of my blow dryer, and go to bed. It does itch for about 20 minutes, but I'll take that side effect any day over sweating. Thankfully I haven't had any issues with my arms burning. If you're looking for relief from underarm sweat, I definitely recommend this medication. So far, it has been a life changer."
