1 Masseter Botox – MD Skin Lab Canada

Masseter Botox
(for Jaw Clenching & Facial Slimming)

Do you suffer from jaw tension, teeth grinding, or a square jawline caused by overactive muscles? Masseter neuromodulator treatment may be the solution you've been looking for. At MD Skin Lab, our skilled physician injectors use Health Canada–approved neuromodulators, such as Botox® to safely and effectively relax the masseter muscle, the large jaw muscle responsible for clenching and grinding. This non-surgical, minimally invasive treatment can help reduce pain, improve headaches, prevent further dental damage, and even slim the face for a more sculpted, V-shaped appearance. 

Whether your goal is therapeutic, cosmetic, or both, masseter botox is a personalized treatment that may help improve comfort and facial balance. As this muscle weakens slightly over time with this treatment, the results can include a contoured jawline, fewer headaches, and overall relief from jaw-related tension.

Masseter Botox Explained 




What is Masseter Botox?

Masseter botox is a targeted use of neuromodulator injections, including Botox®, Dysport®, Xeomin®, or Nuceiva®, that focuses solely on the masseter muscle, located at the sides of the jaw. This treatment temporarily relaxes the muscle to alleviate excessive clenching and grinding (a condition also known as bruxism) and to help slim the appearance of the jawline. 

Overactivity of this muscle can lead to issues like tension headaches, jaw pain, TMJ symptoms, and even a bulky or square jawline. By injecting a neuromodulator directly into the masseter, we can reduce muscle activity without affecting your ability to chew, talk, or express yourself naturally. It’s a subtle, effective way to address functional and aesthetic concerns.


How Does Masseter Botox Work?

Neuromodulators, like botox, dysport, xeomin and nuceiva work by temporarily blocking the nerve signals that trigger muscle contractions. When used in the masseter, this leads to reduced muscle activity, which not only eases tension but can also decrease the size of the muscle over time, resulting in a slimmer, softer jawline. 

This is a precise, localized treatment. Our physicians carefully assess your facial structure and muscle activity before injecting the neuromodulator to ensure the correct dose is delivered to the right area.

How Many Appointments Will I Need And When Will I See The Results?



You can expect a reduction in tension and grinding within 7–10 days, with full results evident by 3 weeks. If jaw slimming is one of your goals, this effect becomes more noticeable over 4–6 weeks as the muscle gradually reduces in size. 

We recommend returning every 3–6 months for maintenance, depending on your goals and how your body metabolizes botox./p>

Side effects are typically mild and temporary, and may include:

  • Slight swelling or tenderness at the injection site
  • Minor bruising
  • Temporary chewing fatigue (usually resolves in a few days)
