Muscle denervation is the medical term for Botox. Usually, a nerve transmits a signal to the muscle to make it contract. Neuromuscular junction is the place where the nerve and muscle touch. A substance named acetylcholine is freed from the nerve side of the neuromuscular junction when the signal gets to it. This chemical also holds to the junction’s muscle side, causing the muscle contract by creating more chemical reactions.

Botox works as a acetylcholine receptor blocker on the junction’s muscle side. This is how it works. When the muscle receives a signal to tighten from the nerve, the acetylcholine that is released cannot cling anywhere on the muscle. The muscle has no clue that it needs to tighten. It is essentially immobilized without hurting it or the nerve.

The acetylcholine blockade begins within 48 hours and is irreversible. Between 5-10 days, the Botox in Merced clinical effects become apparent. The muscle will be able to slowly contract again over the next 90-120 days by growing new receptor sites. Wrinkles are prevented from forming when the muscle is incapacitated. This muscle paralysis happens when Botox is injected into a wrinkle-causing muscle in the overlying skin. Botox works best on wrinkles that are only caused by muscle contraction.
