Also known as hyperhidrosis to reduce excessive sweating in the armpits
In people with hyperhidrosis the nerves that signal the sweat glands are overactive. Botulinum toxin treatment works by blocking the nerves responsible for activating your sweat glands. When you receive these injections directly into the area of your body that commonly sweats, your overactive nerves are essentially paralysed. When your nerves can’t signal your sweat glands, you don’t sweat. One treatment usually lasts around 6-9 months.
