How does Botox work to reduce sweating?
You sweat when the nerve endings in your skin tell the sweat glands to produce sweat. Botox helps reduce excessive sweating by blocking those ‘messages’.

Once an area has been treated with Botox, the sweat glands will not produce sweat for up to six months.

Botox is not a permanent solution for excessive sweating as your body produces new nerve endings over time, about every six months. As these new nerve endings haven’t been treated with Botox, they will send signals to the sweat glands as normal to start producing sweat.

Using Botox to treat excessive sweating has mixed results. Some patients find they no longer sweat in the area that’s been treated, while others continue to sweat but much less.
