Masseter Botox
Let your jaw finally let go.
Many of us carry stress in the jaw without noticing: clenched through meetings, ground down overnight, held tight long after the day is over. The same strong chewing muscle can also give the lower face a wider, squarer shape. A few small, precise doses of Botox® by Allergan help it soften.

Is this for you?
You may be nodding along if you…
- Wake with a tight jaw, or catch yourself clenching or grinding
- Feel tension or soreness along the sides of your face
- Notice a square lower face that comes from muscle rather than bone
- Would love a softer, slimmer jawline without surgery
Before you book: please tell your doctor about any neuromuscular condition, weakness in the facial or jaw muscles, or trouble chewing or swallowing.
How it works: the muscle that never rests
Place a hand at the side of your jaw and bite down. That firm bulge is your masseter. For many people it works overtime, driven by habit, stress and genetics, until it grows strong and bulky.
Your doctor places Botox at carefully chosen points in each masseter. It quiets the nerve signals that tell the muscle to contract so hard, and the clench, and the tension that comes with it, can begin to ease. You will still chew, speak and smile as you always do.
Where that extra bulk has widened the lower face, the calmer muscle slowly softens and the jawline refines. It is a gentle change that unfolds over weeks, not a sudden one.
What to expect
- Week 1 to 2
The tension in your jaw begins to ease.
- Week 4 to 6
Your jawline starts to show change.
- Month 2 to 3
Your result is at its clearest. Wait until then before deciding on the shape.
- Month 3 to 6
The effect gradually softens, depending on your dose and muscle strength. Many clients return to keep it.
Any redness, tenderness, swelling or bruising settles quickly. Results vary, and your doctor will tell you what to expect for your own jaw.
Your visit, step by step
Before
- Tell your doctor everything you take, including blood thinners, aspirin, muscle relaxants, sleeping medication, injected antibiotics, and allergy or cold medicines
- Keep taking prescribed medicine unless its prescriber tells you to stop
- Mention any botulinum toxin or filler in the last four months
- Share any allergies, uneven bite, jaw joint problems, dental infection, past facial or jaw surgery, planned dental work, or reactions to earlier botulinum toxin
- Skip alcohol the day before, as it can increase bruising
- Arrive with clean skin and little makeup on the area
The day
Your doctor feels both sides of your jaw as you clench and relax. If one muscle is larger or stronger, each side can be dosed differently. The injections are brief pinches, with numbing cream if you would like it, and then you go on with your day.

Questions people ask
The masseter is the muscle you feel tighten at the side of your jaw when you bite down. Your doctor places small doses of Botox® by Allergan at chosen points in each masseter. This quietens the nerve signals that make it contract so hard, so jaw tension and clenching can ease.
It can. Clenching and grinding keep the masseter working overtime, and relaxing it can ease the tension and soreness that come with them. Your doctor will assess your jaw at your consultation.
Where muscle bulk has widened the lower face, the quieter muscle gradually shrinks and the jawline narrows. This happens slowly, and it only applies when the width comes from the muscle.
Yes. The muscle still does its job. Botox only softens the strongest contractions.
Jaw tension often eases within one to two weeks. Your jawline changes more slowly, showing from four to six weeks and clearest at two to three months, so please wait before deciding how it looks.
Three to six months, depending on the dose and your muscle strength. Results vary, and your doctor will tell you what to expect for your own jaw.
The injections are brief pinches, and numbing cream is available if you would like it.
Minimal. Any redness, tenderness, swelling or bruising soon settles, and you go back to your day afterwards. Please avoid strenuous exercise, saunas, steam rooms and intense heat for 24 to 48 hours.
Not always. Your doctor feels both sides of your jaw as you clench and relax, and may dose each side differently if one muscle is larger or stronger.
