Depending on where I am in my monthly cycle, my hormones go crazy at night and I sweat a ton. I decided to try this deodorant out at night during that time frame and it really helped. I noticed one night that I was sweating like crazy, so the next night I put this on before going to bed. I still sweated but it was noticeably reduced under my armpits and I didn't smell like stinky armpit sweat when I woke up!
To me it smells like clean laundry. It goes on clear and does not seem to leave residue behind.
