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.
Often considered the "first line" of treatment for severe underarm sweating, over-the-counter 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.
Deodorants help control body odor, which is caused by a reaction between bacteria and sweat. The deodorants work by making the skin more acidic, and hence less attractive to bacteria. They are often used in combination with antiperspirants to help control sweating in addition to odor.
Your doctor may prescribe a stronger antiperspirant for your severe underarm sweating, available from your pharmacist. Like over-the-counter antiperspirants, these also work by blocking sweat ducts, thereby reducing the amount of perspiration that reaches the skin.
