Aluminum chloride hexahydrate
"I have been struggling with excessive underarm sweat since I hit puberty. I had tried literally everything and nothing even slightly helped. One day I was at the drug store and spotted drysol, I was a bit reluctant by the price but my desperation decided to give it a shot. Just after a few nights of using the product I saw results. Using drysol has literally been the best decision of my life, I am no longer anxious and embarrassed about my underarms and can wear anything I'd like!!! Although it did make it hard to sleep at night due to the itchiness and slight burning but I say it's totally worth it, and eventually I got used to it and it wasn't so bad. Definitely recommend!!!"
