Aluminum chloride hexahydrate
"I have had hyperhidrosis since the 6th or 7th grade and it really is one of the worst things that you can have when you are trying to have a social life. I started hypercare 3 days ago and it works like magic. Like many others was stuck to wearing black and white Ts and tank tops. Not anymore. The first day I got it I wore grey. Not a sweat mark at all. The only downside is that the pain of it is horrible, because it burns so bad. I'm only on my third day and I hope that it starts to lessen soon but other than that, it truly is a blessing."
