Aluminum chloride hexahydrate
"I'm 35 and have had a problem with sweating since high school.  Shortly after high school I started taking birth control pills, and the problem stopped.  I stopped taking the pill last year and within a few months I noticed my sweating was starting again.  I don't know if it was because of the birth control pills or not.  I was embarrassed to bring it up to my doctor, but I finally did.  I couldn't lift up my arms at all at work because of the sweat marks. You take Hypercare for a few days at first and I was so excited that I stopped sweating.  I could finally wear thin colored shirts and not have sweat marks anymore. The only side effect I've had is the itching, intense at times at night when I have it on. Once or twice I've had to wash it off. But 100% worth it."
