text: Get Certain Dri. You will never sweat from your underarms. Eliminates all odor. Has no smell. Has no residue so it does not stain your clothes at all. It is a roll on you can get at any drug store in the anti-perspirant section. You put it on at night. Go to sleep. Wake up and take a shower. The residue of the anti-perspirant is gone, but you don't sweat or smell at all for a couple of days. And when I say you don't sweat or smell I mean it. I go to the gym and my shirt gets soaked except for under the arms. That is how well it works. I have not sweated under my arms for over ten years since starting to use this product, and nothing else was able to stop the sweat.
