hyperhidrosis
"I LOVE this product. I just started using it yesterday and it already stopped my sweating. I can raise my hand, stretch, and participate in gym activities. The only bad part about this is the stinging. I did shave that morning, and I applied it at around 8:00pm. It felt like someone was pricking me with a needle for about 20-30 minutes, but it definitely subsided after that and I was able to sleep, shower,

 and apply deoderant. It is SO worth some sting to stop the sweat and not have deoderant caked on my shirts."
