I've got quite a sweating problem as well. I'm 15, female, and sometimes I'll sweat tons, mainly all on my underarms - mostly because of stress and anxiety, I think, in social situations more than heat or exercise (I do sweat with exercise etc, pretty much normal amounts, and not my underarms so much. weird). I have no problem at all with smell, but It still sucks, because it ruins white/light coloured shirts and shows large wet spots
. I use Ban deodorant, which works ok, and smells extremely good. But once it is sweated (is that a word, lol) off, it doesnt do much. anyways, thats great I found this, maybe I'll use Certain Dri or something! anyway, good luck! let us know how it works for you!
