 drinking water helps but you need backup in the urban jungle heat and for me nothing has come close to the protection i receive from the insanely expensive donna karen's cashmere mist deodorant i think i've said it before but i'll say it again this stuff works it's a do not pass go full stop for sweat i don't know what's in it i'm not a chemist but i do know it's aluminum free and alcohol free i just wish it was free free oh and it's got a nice powdery scent too
