Masseter Contouring
Masseter Contouring in Las Vegas
Xeomin or Dysport injected into the jaw muscle to soften a square jawline, ease teeth grinding, and create a more contoured lower face - in our Summerlin suite, or wherever you are in Las Vegas.
The masseter is the strong chewing muscle at the corner of your jaw - and for some people, it's simply bigger and more active than it needs to be, creating a square or bulky jawline. Relaxing it with a neurotoxin injection can soften that shape and take pressure off a jaw that clenches or grinds.
Come by our Summerlin suite, or have one of our licensed nurses meet you at your home, hotel, or office anywhere in Las Vegas.

What It Supports
Why Choose Masseter Contouring?
Xeomin and Dysport are neurotoxin treatments that relax targeted muscles. Used in the masseter, that means less bulk in the jaw muscle itself - not just softer movement, like with a wrinkle-focused treatment.
Slimmer Jawline
Relaxing the masseter muscle softens a square or bulky jaw shape over time, for a more tapered, contoured profile.
Less Jaw Tension
Many clients book this treatment for relief from clenching and grinding, not just the cosmetic result.
Gradual, Natural Change
The muscle shrinks slowly over several weeks, so the slimming effect looks like a natural change rather than an overnight transformation.
Quick, Low-Downtime Visit
A handful of small injections per side, done in about 15-20 minutes, with no real recovery time.
Worth Asking Yourself
Is Masseter Contouring Right for You?
A wider or squarer jawline isn't a problem to fix - but if it bothers you, or your jaw is giving you grief, it's worth knowing this option exists. A few things our clients mention before their first visit:
A square or wide jawline that runs in the family or has become more noticeable over time
Frequent jaw soreness, headaches, or tension from clenching or grinding
A visibly bulky jaw muscle when you clench your teeth
Wanting a slimmer, more tapered lower face without surgery
None of this is a diagnosis - if it sounds familiar, mention it during your consultation and we'll talk through whether this treatment makes sense for you.
The Appointment
What Actually Happens During Your Visit
1. Consultation & Health Screening
We'll feel how the masseter muscle engages when you clench, talk through your goals, and review your health history.
2. The Injections
A handful of small injections into the masseter muscle on each side, with a very fine needle - most clients describe it as a quick pinch.
3. Back to Your Day
No numbing required for most clients, no real downtime. Mild soreness when chewing is normal for the first few days.
4. Results Build In
Jaw tension often eases within a week or two. The visible slimming takes longer, building over 4-8 weeks as the muscle gradually shrinks.
Treatment Details
What to Expect
Who It's For
Anyone bothered by a square or bulky jawline from an overactive masseter, or dealing with jaw tension from clenching or grinding, who wants a non-surgical way to soften their jawline.
Who Should Avoid This
Not recommended during pregnancy or breastfeeding, for those with a neuromuscular condition such as myasthenia gravis, or with a known allergy to the product or its ingredients. A health screening confirms whether this treatment is right for you.
Aftercare
Skip vigorous chewing or massaging the area for the rest of the day, and avoid lying down or rubbing the treated spots for about 4 hours afterward.

Frequently Asked Questions
Masseter Botox is the common name for injecting a neurotoxin - Xeomin or Dysport in our case - into the masseter muscle, the strong chewing muscle at the corner of the jaw. It relaxes the muscle to soften a square jawline and ease jaw tension.
Two main reasons: cosmetic jawline slimming for a more tapered lower face, and relief from jaw tension caused by clenching or teeth grinding. Many clients come in for one and appreciate both.
The masseter is a muscle, and like any muscle, it shrinks when it's used less. Relaxing it with a neurotoxin injection reduces its activity, and over several weeks the muscle gradually shrinks, softening a square or bulky jaw shape.
Masseter Contouring is one approach to jawline contouring - a non-surgical one. It works especially well when a wide jaw shape comes from an overactive or enlarged masseter muscle rather than the underlying bone structure.
Jaw tension often eases within the first week or two, but visible slimming takes longer since it depends on the muscle actually shrinking - most clients start noticing a change around 4-8 weeks, with full results by about 3 months.
At the doses we use, most clients don't notice a difference in normal chewing. Very hard or chewy foods might feel like slightly more effort right after treatment for some people, but that typically resolves quickly.
Many clients find real relief from clenching and grinding discomfort. It's not a replacement for a night guard or a TMJ treatment plan from your dentist, but it can be a helpful addition - we're happy to talk through how it fits with any care you're already getting.
Most clients see results for about 4-6 months, a bit longer than typical wrinkle-focused neurotoxin treatment, since it's working on muscle bulk rather than just movement. Regular treatment keeps the muscle smaller over time.
Yes - plenty of clients pair Masseter Contouring with one of our IV therapies, like Flawless Fusion IV, in the same visit. Just mention it when booking.
