-raises hand- i have that!
like kpxkimcheexyoja said, it's a condition called hyperhidrosis. i have it on my palms, my underarms, and the soles of my feet. NOTFUN. i went to my doctor about it and got that drysol thing, but it didn't work for me =T so i just stopped using it lol.
i recently started using secret clinical strength and that's done this much for me: ZERO. it's the same as any other antiperspirant for me, which i'm not surprised because if you look at the active ingredient, it's the same ingredient as some of secret's other antiperspirants, only it's concentrated at 20% whereas some of the other ones are at 19%. idk how much of a difference 1 percent makes, but in my case, it's not a lot.
just be thankful it's only when you're hot or nervous, cause that's usually when people sweat, so i wouldn't worry about it too much. i sweat pretty randomly, or if i just think about it, not only when i'm hot or nervous. you might actually grow out of it because i remember it being managable in elementary school, really bad in middle school, and now it's a tiny bit better. [: but for now just try to stay away from touching hands with anybody when yours are wet, or just explain hyperhidrosis to them. they're nice people, they'll understand. [: what's better is if you just tell them that your hand is wet before you touch them. takes the surprise out of it lmao.
Yo bro am in the same boat as ya, antiperspirant never works (totally useless imo), meds work to a degree (side effects are insane) and surgery...(dont even wanna consider that). The only thing that i have had success with is iontophoresis machine, it hurts a bit but it totally eliminates hyperhidrosis.
Iontophoresis machine: $1300 AUD
