Understanding Masseter Botox Injections
The masseter muscle, one of the primary muscles involved in chewing, is located at the angle of the jaw and is among the strongest muscles in the human body. Botox injections targeting this muscle have gained popularity as a non-surgical solution for various aesthetic and medical concerns. When injected, Botox blocks the release of acetylcholine, a neurotransmitter responsible for muscle contraction, temporarily paralyzing the muscle.
Duration and Timeline
The effects of masseter Botox typically follow this progression:
- Initial onset: 3-7 days
- Peak effects: 2-4 weeks
- Total duration: 3-6 months
Individual results may vary based on:
- Dosage administered
- Individual metabolism
- Muscle strength and size
- Previous treatments
