Aluminum chloride hexahydrate
"I used Hypercare for the first time 2 nights ago and the next day when biking I DID NOT SWEAT. I had been suffering from really bad sweating since the middle of 9th grade. By the time 10th grade started I figured that it would go away, it didn't. Almost 4 months after 10th grade started I decided to try this product. I was a little skeptical at first as I had tried almost every deodorant known to man, even clinical strength, and yet none of them worked and only made the sweating worst. However one day after using Hypercare I'm no longer sweating even while doing physical activity. I'm going to report back in about a week to say how it works in school since I feel it would really benefit those who check this site out."
