Its for those of us who sweat alot. In summertime i have to apply 24hr deoderant 3 times a day because otherwise i stink! i only have to walk fast for 10 mins and ill be dripping with sweat! its gross! So i think its a great idea. I have always been to embarrassed to see a doctor about it but i am glad they have released something i can use. You use it before bed time and it soaks into the skin and its actually 48hr protection so may work for 24hrs on me
