How does botulinum toxin counteract heavy sweating?
The treatment of hyperhidrosis (excessive sweating) is an important way in which botulinum toxin is used other than its cosmetic applications. Hyperhidrosis of armpits, hands and feet can be decreased dramatically through intradermal injections of botulinum toxin which ox is able to temporarily block the activity of the nerve fibres connected to the sweat gland and therefore block the secretion of sweat.
