hyperhidrosis
"Wow! I had been struggling with excessive underarm sweating for several years, and more recently the sweating was made worse by a prescription medication. I wore only black and other dark colors for months, and I couldn't even wear sleeveless tops because the sweat would sometimes drip down my arms. Finally went to my doctor in frustration and she immediately prescribed Xerac AC, noting that this had worked for many of her patients. I used it very sparingly the first night (dabbed it on carefully), mainly because I'd read about the potential for stinging discomfort. The next day I was still sweating, but only about 1/4 of what I had been. The next night I applied a bit more and it only stung a bit. Next day, NO SWEAT. Recommended!"
