What Is Masseter Botox?

Masseter Botox is a treatment where Botox is injected directly into the masseter muscles, also known as the chewing muscles. These muscles sit at the angle of the jaw and help with chewing, clenching, and grinding. When the masseter muscles are naturally strong or become enlarged from repeated clenching or grinding, they can make the lower face appear wider or more square.

By relaxing the masseter muscle, Botox reduces how hard the muscle works. Over time, the muscle can decrease in size, which may create a slimmer, softer lower face. Many clients also report added relief from jaw tension, clenching, grinding, and TMJ-related discomfort.

Who Performs Masseter Botox at Dam Medspa?

Masseter Botox at Dam Medspa is performed by Uy Dam, NP, a nurse practitioner with more than 7 years of experience in medical aesthetics. Uy has performed hundreds of Masseter Botox treatments and takes a conservative, detail-focused approach to facial balancing and injectable treatment.

Because Masseter Botox requires thoughtful dosing and precise placement, choosing an experienced injector matters. Proper technique helps improve results while reducing the risk of unwanted side effects.

Who Is a Good Candidate for Masseter Botox?

You feel your lower face looks wide or square
You notice bulky jaw muscles when clenching
You grind or clench your teeth
You experience jaw tension or soreness
You want a slimmer lower face without surgery
You prefer a treatment with little to no downtime

The best candidates are often clients whose lower facial width is caused mainly by enlarged masseter muscles rather than bone structure alone. During your consultation, your facial anatomy and muscle strength will be assessed to determine whether Masseter Botox is a good fit.

The Masseter Botox Process

1. Consultation and Assessment

Your appointment starts with a consultation to review your goals, symptoms, and facial anatomy. You may be asked to clench your jaw so the masseter muscles can be evaluated for size and strength.

2. Personalized Treatment Plan

Your dosing plan is customized based on how strong and enlarged your masseter muscles are, your facial balance, and your desired outcome.

3. Cleansing and Marking

The skin is cleansed and the treatment area may be marked to guide safe, accurate injection placement. Proper placement is important because the masseter sits near other muscles involved in facial expression.

4. Botox Injection

Botox is injected directly into the masseter muscles using a fine needle. The treatment is quick and generally very tolerable.

5. Aftercare Instructions

After treatment, you will receive guidance on what to expect over the next several weeks, including when visible slimming may begin.

Average Masseter Botox Dosing

Masseter Botox dosing is personalized. It depends on the size of the muscle, how strong the muscle is, and your desired result.

At Dam Medspa, the average dose is about 20 to 25 units per side.

20 units per side = 40 units total
25 units per side = 50 units total

Some clients may need more or less depending on their anatomy and muscle activity. Proper dosing matters because underdosing may lead to less improvement or increase the chance of issues like paradoxical masseteric bulging.

Masseter Botox Pricing

At Dam Medspa, Botox is $13 per unit. Since Masseter Botox is priced by unit, your total depends on your personalized dose.

Example 1

20 units per side

40 units total

$520

Example 2

25 units per side

50 units total

$650

This per-unit pricing model allows treatment to match your actual muscle strength and needs rather than using a one-size-fits-all flat fee.

What to Expect After Masseter Botox

Masseter Botox works gradually. Because the goal is to relax and shrink a strong muscle over time, the slimming effect is not immediate.

Most clients notice visible jaw slimming around weeks 4 to 6. As the masseter becomes less active, the lower face may begin to look softer and less bulky.

Little to no downtime
Gradual improvement over several weeks
Visible slimming often around 4 to 6 weeks
Possible relief in jaw tension for some clients
Temporary results that require maintenance

Mild tenderness, swelling, or small bumps at the injection sites can happen, but these are usually temporary and resolve on their own.

Added Benefits of Masseter Botox

While facial slimming is usually the main cosmetic reason clients choose this treatment, many also enjoy added functional benefits.

May reduce jaw tension
May help with teeth grinding
May help with clenching
May improve discomfort related to overactive jaw muscles
May help some TMJ-related symptoms

Although many clients report these benefits, results vary from person to person, and treatment at a medspa is not a replacement for a full dental or medical evaluation when jaw pain is severe or persistent.

Possible Complications of Masseter Botox

Masseter Botox is generally well tolerated when performed by an experienced injector, but complications are possible with any injectable treatment.

Crooked Smile

This can happen if Botox relaxes a neighboring muscle involved in smiling. It is usually related to placement or dosing issues.

Paradoxical Masseteric Bulging

This can look like a walnut-shaped bulge at the jaw when clenching. It may happen from underdosing or from not adequately treating both the deep and superficial portions of the masseter.

Bruising, Swelling, or Tenderness

These are usually mild and temporary.

Complications are uncommon, but they can happen. Careful assessment, dosing, and placement are important for reducing risk.
