I'm a female age 21. I need help getting rid of and controlling underarm sweating and odor. I take showers frequently and I use deodorant. I tried Mitchum it only worked for a while then I started to get itchy bumps on my arm pits. I tried Secret Clinical Strength in regular form and in sensitive skin and both don't help. I'm not sure what else to do. I tried rubbing alcohol and it doesn't help. I keep my underarms shaved and everything. Any suggestions?
