What should i do about my under arm excessive sweating
You can try an antiperspirant called B+Drier. I use it once a week and regular antiperspirant every day.
B+Drier is not like regular antiperspirant. You must shower at night, apply it under your arms, go to bed, wake up and shower it off in the AM.
I get it a Walgreens
Good luck
Instead of deodorant or antiperspirant, apply baby powder.
It's drier.
The best kind I've ever used is from the Dollar Store. It's called Alibi. For Babies and Adults. Hypoallergenic Baby Powder.
You may actually be allergic to some types of deodorant and antiperspirant, and that can cause excessive perspiration.
Treatment Options
A number of different treatments and products are available to help people with severe underarm sweating. Here's an overview of some you may have heard about or considered trying. If you have any questions about which treatment option may be right for you, speak with your dermatologist.
Antiperspirants/Deodorants
Often considered the "first line" of treatment for severe underarm sweating, over-the-counter and prescription antiperspirants work by blocking sweat ducts, thereby reducing the amount of perspiration that reaches the skin. The most widely used ingredients in antiperspirants are metallic salts, including aluminum chloride hexahydrate. Antiperspirants can cause skin irritation, and higher concentrations of aluminum chloride can be destructive to fabrics.
