Heavy sweating without doing anything ?? Use the Sebamed deodorant, works very well. After a week or two, you notice the difference. then you will be sweating as "normal".
Especially in the summer it bothers you, without doing anything the sweat ran down my side.
If you now before you shave your armpits just rub with lemon juice and let soak 10 minutes and after shaving some talcum powder on it, that helps me.
