Is Certain Dri ok to put on other areas of perspiration?

I've read the instructions over a few times to make sure I know what I'm doing, and I'm confused about a couple of things. First of all, it comes with this ball thing on top that is pretty dry, so am I supposed to hold it upside down and apply it to my underarms?





Even though it works for up to 3 days, should I still use it daily for maybe the first week or so? What would happen if I use it too often?





Lastly, and my most important question: Why does it only recommend you to use it for your underarms? I don't see the problem of applying it to other areas of perspiration. When reading the instructions, it says that this army sargent recommended to put it under your feet before a long walk or run.





This makes me think it would help to apply it to any perspiration glands. Because the way I see it, I have hyperhidrosis, which affects me in many places, like my forehead, armpits, lower back/thigh area, and to a lesser effect on the rest of my body.





So what's wrong with applying it there?

You can and should use it daily after a shower.Only for your arm pitts.


Nowhere else.


Other areas that are to wet you can apply talcum powder.Rub that in.
