I sweat a lot, I move or not, I even sat flows under the armpits, this is very embarrassing ... A few months effective than "normal" in the month but this one does not burn my skin, apply more often, that's all. I recommends that they product without hesitation to all those who sweat excessively like me, I hate to be able to spend the summer without running constantly !!!! If you have a resistant skin try rather normal, being stronger need for less frequent applications.
