The main objective of Botox is to reduce wrinkles and fine lines without inhibiting muscle movement but it can also be performed into the skin to treat the symptoms of severe underarm sweating (severe axillary hyperhidrosis). People having this disorder often suffer from difficulty in social situations.
When Botox is injected into the skin, the treatment affects the signal between the nerve endings and the sweat glands in the dermis. The botulism toxin binds itself to the nerve endings near the injection site and acts like a roadblock. It blocks the release of the neurotransmitter acetylcholine, a chemical our nerve cells make to communicate with each other, and this disrupts the message sent from the nerve endings to stimulate the production of sweat.
