There's actually a health condition for situations like this. Everyone sweats but when you get to the point where you sweat in temperatures that you normally wouldn't then that's a little abnormal. The condition is called hyperhidrosis if you want to google it and look into other advice. I don't have that but I do sweat a lot under my arms. I think my pores are just larger than normal though. What I've used for years is Certain-Dri. It usually always works but READ the instructions. If you shave or shower right before using it, it will hurt and itch. I suggest to put it on at night and keep your arms raised above your head so it would dry.
