It's the pitts to have sweaty underarms. How would I know, you ask? Because I am 1 in 4 women who have a sweating problem. Whether it's because I am nervous, being around someone far superior to me...or just sitting at my desk at work, I have a problem. About four days ago I bought something to help my problem. While it has 12% aluminum, it seems to be working better than deoderant's I have used in the past with 19% aluminum.
