Why Botulinum Toxin Injections Take Time to Work

Patients may notice the results of botulinum toxin injections after fourteen days. Botoxbinds with the muscles and nerves. The nerves signal the movement of muscles, and the megaphone signals them to contract. Specifically, this medication binds to SNARE, a protein in the body responsible for sending chemical communicationssignalling muscle movement. Without the release of the chemicals, muscle movements are impossible. Therefore, anti-wrinkle treatments interfere with the communication between the nerves and muscles.

Though the botulinum toxin’s binding to the SNARE protein takes place almost instantly, what takes it time is, shutting off and silencing acetylcholine. This may take multiple days.

How Botox Feels Once It Starts Working

  • After the procedure, you may feel a slightly tight sensation; however, it will subside in around two weeks.
