What Is Botox® Face Slimming?
Botox® jaw slimming is an injectable treatment that uses botulinum toxin type A to relax an overactive masseter along the jawline. As muscle activity decreases, the muscle gradually reduces in volume, resulting in a slimmer, more refined lower face. This treatment is ideal for anyone looking to improve their facial shape without surgery or downtime.
Treatment Specifications
- What is injected: Botulinum toxin type A
- Mechanism of action: Blocks acetylcholine at the neuromuscular junction, relaxing the masseter
How Botox® Jaw Slimming Works
On a physiological level, Botox® works by temporarily blocking nerve signals to the masseter muscle, reducing both its activity and volume. On a technical level, your physician uses fine-gauge needles and precise anatomical mapping to ensure symmetric injection sites and balanced dosing on both sides. Over the weeks following treatment, as the muscle gradually relaxes, the jawline takes on a noticeably slimmer, more refined contour.
Core mechanism of action
Masseter Botox / Jaw Slimming works by blocking acetylcholine at the neuromuscular junction, which lets an overactive masseter relax and reduce in bulk over several weeks. Our physician customizes parameters based on your bruising risk, muscle bulk, and skin characteristics, balancing efficacy with safety.
Am I a Candidate for Botox® Jaw Slimming?
- A wider or squarer lower face due to prominent masseter development
- Seeking a slimmer, more defined V-shaped facial contour
- Symptoms of bruxism or temporomandibular joint (TMJ) tension
- Prefer a non-invasive treatment with minimal to minimal downtime
- Seeking naturally refined improvement
- Not suitable for the following:
- Pregnancy or breastfeeding
- Patients with neuromuscular disorders
- Patients with known allergy to botulinum toxin or its components
