BOTULINUM TOXIN A,
acts as an inhibitor, blocking
the chemical signals sent from
the nerves that control sweating. Sweating stops because the
sweat glands are unable to receive signals from the nerves.
Areas which are commonly treated are the under-arms
and the palms.
It is well known in Hollywood circles that stars often receive BOTULINUM TOXIN A Cosmetic Botox® injections a few days before high-profile events to control excessive under-arm sweating.
