I bought this antiperspirant because I sweat on my face and needed something that would help since I didn't want to use regular antiperspirant on my face. Basically you apply the spray at night once or twice a weekly before bed, You don't want to use it in the daytime . When you spray it on it can burn a bit for a few minutes then the pain goes away. It didn't stop my sweating , I still sweat while using it I just sweat a bit less. when I stopped using it all together I sweat more than I did before using it.
