Masseter Botox: A Targeted Treatment with Life-Changing Results Boston Medical Aesthetics

One of Boston Medical Aesthetics' Most Popular Treatments

If you've ever noticed a square or widened jawline when looking in the mirror, or if you struggle with clenching, grinding, or tension in your jaw- you’re not alone. One of the most effective and transformative treatments we offer at Boston Medical Aesthetics is Masseter Botox, and it’s one of our most in-demand services.

What Is Masseter Botox?

The masseter muscle is a strong muscle located at the angle of your jaw, responsible for chewing. For many people, this muscle becomes overactive from habitual clenching or grinding (a condition known as bruxism), often leading to jaw pain, tension headaches, and a bulky or square appearance in the lower face.

By injecting Botox or Dysport into this muscle, we can temporarily relax it- reducing its size over time, relieving discomfort, and softening the jawline for a more balanced facial profile.

Why Do People Get It?

There are both aesthetic and medical reasons people choose masseter Botox:

• Facial Slimming: Reduces the appearance of a wide or boxy jawline for a more contoured look
• Jaw Tension Relief: Alleviates tightness, soreness, and fatigue in the jaw
• TMJ Symptom Relief: Helps reduce symptoms of TMJ (temporomandibular joint disorder), including jaw clicking, headaches, and discomfort
• Teeth Grinding & Clenching: Can dramatically reduce night grinding and protect dental health
• Facial Balance: Restores harmony and proportion to the lower face

Who Is a Good Candidate?

You may be a candidate for Masseter Botox if you:

• Experience frequent jaw clenching, grinding, or facial tension
• Have a square or overly prominent jawline that feels bulky to the touch
• Struggle with tension headaches or TMJ-related symptoms
• Desire a slimmer, softer lower face without surgery
• Are in overall good health and have realistic expectations

At Boston Medical Aesthetics, our experienced injectors will assess your facial anatomy and goals to create a plan tailored just for you.

What to Expect from Treatment

Masseter Botox is quick and requires no downtime. The treatment typically takes just a few minutes and involves a few small injections on each side of the jaw.

Results begin to appear within 2 weeks, with full slimming and muscle relaxation typically seen at 6-8 weeks. Most patients enjoy results for 3-4 months, with regular maintenance treatments recommended for continued benefit.
