I've posted about my hyperhidrosis before, and sadly that's remained a problem even after getting rid of the odor. I use vast amounts of foot powder and my feet still get uncomfortably wet throughout the workday. It's also not too cool sharing what seems like a fl oz of sweat when I shake hands with someone :]
But some days ago I bought a lb of pure zinc oxide powder from Amazon.... and let me tell you my feet have never been so dry in my life. I use it like normal foot powder.... I cannot praise it enough. I've tried all the antiperspirants you can imagine, I've received prescription creams and ointments in the past, I've even tried herbs and random things I heard could work. None of them helped in the slightest... But when I applied zinc oxide, no lie, right away I could tell the difference! This stuff is from the heavens, I highly highly highly recommend it to anyone with any hyperhidrosis.
I even put it in bath water and soaked myself in it for an hour to see what effects it would have. (Don't put your head in though, better not to have it go in your eyes or mouth.) And WOW I haven't leaked a single drop of sweat in like 18 hours, it's pretty ridiculous how well it works. My main problem is sweaty feet and palms though, so idk if Ill do that again.
TO ANYONE USING ZINC OXIDE: It is non toxic, but can still hurt you if you inhale the fine powder, so please be very careful not to breathe it in.
