CHAPTER FIFTY-ONE: Masseter ‘tox: For Jaw Slimming, Clenching & Migraines

When most people think of ‘tox (neurotoxin) injections, they immediately picture smoothing forehead lines or softening crow’s feet. But one of the most underrated (and truly transformative) uses of ‘tox is in the masseter muscle — the strong jaw muscle located at the back of the jawline.

Masseter ‘Tox is a favorite among our clients not just for its jaw-slimming effects, but also for the relief it can offer from clenching, grinding, & even tension-related migraines. Here’s everything you need to know about this multi-benefit treatment.

What Is the Masseter Muscle?

The masseter is one of the main muscles we use to chew. For some people, especially those who unconsciously clench or grind their teeth (a condition called bruxism), this muscle becomes enlarged over time, leading to:

• A more square or wide lower face

• Tension in the jaw or neck

• Headaches or migraines

• Damage to teeth or dental work

What Does Masseter ‘Tox Do?

‘Tox temporarily relaxes the masseter muscle, allowing it to soften & shrink over time with less activity. This can result in:

Jawline Slimming

• As the muscle shrinks, the face takes on a softer, more V-shaped appearance.

Relief from Clenching & Grinding

• With less muscle activity, you may notice fewer headaches, less soreness in the jaw, and better sleep.

Migraine Support

• Many patients who experience tension-related migraines find relief after treatment, especially when the masseters are a trigger point.

What to Expect from the Treatment

Quick: Treatment takes less than 15 minutes.

Minimal Downtime: You may feel a bit tender at the injection site, but most return to their routine immediately.

Gradual Results: Slimming effects develop over 4–6 weeks as the muscle softens.

Duration: Results typically last 3–5 months.

Is It Right for You?

Masseter ‘Tox is ideal if you:

• Struggle with jaw tension, clenching, or grinding

• Want to slim the lower face without surgery

• Experience stress-induced headaches or tension migraines

• Prefer a non-invasive treatment with subtle, natural results
