Your treatment is placed by Genniel, RN, a Clinical Aesthetic Nurse Injector at InjectCo Austin.

The Treatment, Explained

What Does Botox Treat?

Masseter Botox works on the lower face and the jaw. Here’s where it helps:
  • A wide or square jaw, often from a strong or overbuilt jaw muscle (masseter hypertrophy), softens as the muscle relaxes and shrinks a little over time.
  • A heavy lower face, when the jaw looks bulky from the sides, becomes more tapered for a slimmer side profile.
  • Jaw clenching and grinding, especially at night (bruxism), eases as the muscle relaxes, which many patients feel as less soreness.
  • TMJ tension, the ache and tightness around the jaw joint, can improve when the muscle is calmer.
  • Tension headaches tied to clenching sometimes ease as well, since the jaw muscle is doing less overwork.

Your nurse injector at InjectCo will tell you whether your goal is mostly cosmetic slimming, clench relief, or both, and dose accordingly.

Is This Right For You

How Does Masseter Botox Slim the Jaw?

Your masseter is the muscle you feel flexing when you clench your teeth. When a muscle is used every day, from chewing, clenching, or grinding, it can grow larger and widen the jaw. Botox relaxes that muscle so it works less, and over several weeks a less-used muscle gets a little smaller. As it shrinks, the jaw looks softer and slimmer.

Slimming is gradual. Many patients start to feel less clenching within a week or two, but the visible slimming builds over about four to eight weeks and can keep improving with repeat treatments. Results commonly last around three to four months at first, and often longer once you have had a few rounds, as the muscle stays smaller when it is treated regularly.

PRODUCT OPTIONS

Botox Brands We Use for Jaw Slimming

InjectCo Austin uses FDA-approved neuromodulators for the masseter. Here are the options your nurse may discuss:

Botox

is the most studied neuromodulator and the standard choice for masseter treatment. It is what most patients ask for by name.

Dysport

is another FDA-approved option that some injectors use for larger muscles. Your nurse can explain how it compares for your jaw.

Xeomin

is a purified neuromodulator with no added proteins, which some patients prefer.
Your nurse matches the product and the dose to your muscle and aesthetic goal, and recommend a suitable treatment plan.
Your nurse walks you through every option. No pressure to decide on the spot.
TRANSPARENT PRICING

How Much Does Jawline Slimming Botox Cost in Austin?

Pricing starts at $12 per unit. The masseter is a large muscle, so jawline slimming usually uses more units than a small wrinkle area, which is normal for this treatment.

What drives your cost

Why it matters

Units per side
The masseter often needs a meaningful dose on each side
Muscle strength
A stronger, larger jaw muscle may need more units
Your goal
Slimming plus clench relief may use a slightly different dose

Masseter treatment commonly uses about 20 to 30 units per side, so both sides together often land around 40 to 60 units total, though your exact plan is set at your consultation. For instance, 50 units at $12 per unit is about $600 for the pair. You can estimate your own cost with InjectCo’s Instant Price Simulator. Prices are subject to change, and your nurse confirms your units and total before treatment.

GOING FURTHER

Balancing the Lower Face

Jaw slimming pairs well with other small touches when your goal is overall balance. Some patients add a little chin filler to lengthen and define the chin, which can make a slimmer jaw look even more tapered from the side. Others combine masseter Botox with a light treatment along the neck or a lip flip for a refreshed lower third.

These are possible additional treatments. Jaw slimming works on its own, and many patients treat only the masseter. Your nurse can show you what a balanced plan might look like, with no pressure to add anything you do not want.

YOUR VISIT

What to Expect at Your Appointment

Here’s how a nurse-led Botox treatment usually goes at InjectCo Austin:

1

Consultation

First, you meet your nurse for a consultation. You talk through your goals, whether it is slimming, clench relief, or both, and your nurse checks the strength of your jaw muscle by having you clench.

3

Treatment

Next, your provider cleans and marks the injection points. Masseter treatment is usually just a few small injections on each side, low on the jaw, with a fine needle. The visit is quick. Most patients return to normal activities right away.

4

Results

Aftercare is simple. Stay upright for about four hours and skip hard workouts, alcohol, and rubbing the area for the rest of the day. Expect clench relief within a week or two and visible slimming over about four to eight weeks.

Simple aftercare

  • Stay upright for a few hours

Frequently Asked

Frequently Asked Questions

Yes. Botox relaxes the masseter, the muscle that widens the jaw when it is overused from chewing or clenching. As the muscle works less, it gradually gets a little smaller, and the jaw looks slimmer and softer from the front and the side. The change is gradual and builds over several weeks, so it looks natural rather than sudden.

Masseter treatment commonly uses somewhere around 20 to 30 units per side, so both sides together often land around 40 to 60 units, depending on how strong your jaw muscle is. A stronger, more built-up muscle usually needs a bit more. Your nurse checks your muscle by having you clench, then confirms your unit plan at your consultation.

Pricing starts at $12 per unit. Because the masseter is a large muscle, jaw slimming often uses around 40 to 60 units total, so a common treatment lands near $600, though your exact cost depends on your muscle and is set at your consultation. You can estimate your total with our online price tool before you come in.

Yes, for many patients. When the masseter relaxes, it clenches and grinds less, which often eases jaw soreness and TMJ tension, and some people notice fewer tension headaches. Many patients come in for the clench relief and enjoy the slimming as a bonus. Your nurse can dose with either goal, or both, in mind.

Results commonly last about three to four months at first. With repeat treatments, many patients find the effect lasts longer, because the muscle stays smaller when it is treated on a regular schedule. When you notice the muscle getting stronger again, you simply book another round.

When it is dosed and placed correctly by a trained injector, masseter Botox is designed to slim the muscle without causing sagging. Poor placement or too high a dose is what raises that risk, which is exactly why a skilled, licensed injector matters. At InjectCo Austin, your nurse places the dose low and precisely to slim safely, and will explain your plan first.

It should not change your smile when it is placed correctly, because the injection sits low in the jaw muscle, away from the muscles that move your mouth. Your nurse maps the area carefully to keep your expressions natural. If you have concerns, bring them to your consultation and your nurse will walk you through exactly where the dose goes.

Tell your injector about every medication and supplement you take at your consultation, including blood thinners and anything that affects your muscles or nerves. Your nurse reviews your full health history and gives you personalized guidance, since this is a medical decision that depends on you. This is general information and not individual medical advice, so your consult is the place to sort out the details.

Botox has a long track record when it is placed by a trained, licensed injector, and masseter treatment is a common, well-understood use. At InjectCo Austin, every treatment is nurse-led, and your nurse reviews your health history first to make sure you are a good candidate. Your nurse will also explain how any rare side effects are handled, so you know what to expect.
