What Is Medical Botox (botulinum toxin A)?
It is a toxin produced by the bacteria Clostridium botulinum, which weakens muscles by blocking nerve impulses transmitted from the nerve endings of the muscles. Botulinum toxin is an approved treatment for blepharospasm and hemifacial spasm.

How Does It Work?
Normally your brain sends electrical messages to your muscles so that they can contract and move. The electrical message is transmitted to the muscle by a substance called acetylcholine. The botulinum works to block the release of acetylcholine, resulting in the muscle not receiving the message to contract. This means that the muscle spasms stop or are greatly reduced after treatment, providing reliable relief from symptoms.

How Long Does It Take to Work?
Benefits begin in 1-14 days after the treatment and last for an average of three to four months.
