Hey guys, if you are truly bothered by sweat, you need to visit the International Hyperhidrosis Society and get the full download on all your treatment options (safty, risks, costs, etc) plus check out the study posted in the REASEARCH section for free treatment of underarm excessive sweating (if you qualify). Their web site is www.SweatHelp.org . They are an independent, non-profit group and have the best dermatologists in the world on the Board. They also have an amazing newsletter that goes out every other month with great updates on research and everything to do with excessive sweating. I've been a member since they started in 2003 and give them my full support. Good luck!
