01
Is the masseter actually enlarged?
Assessment while clenching can help identify whether the chewing muscle contributes meaningfully to lower-face width. A wide jaw does not automatically mean a large masseter.
Masseter Botox · Square-jaw planning
Jaw Botox for square jaw
at Newline Clinic Busan.
Masseter Botox can be relevant when lower-face width is substantially influenced by the chewing muscle. It cannot change mandibular bone structure, and one fixed “Korean V-line dose” does not fit everyone. This Newline guide focuses on confirmed botulinum brands, the clinic's current 60U jaw-Botox price reference, facial anatomy, realistic expectations and travel-aware recovery planning.

If you only read one paragraph
The key question is whether your lower-face width comes from muscle, bone, soft tissue — or a combination.
Jaw Botox works by reducing masseter muscle activity over time. That means a patient with clearly enlarged masseters may see more lower-face softening than someone whose jaw width is mainly skeletal. Newline's current price list uses a 60U square-jaw reference with Liztox, Coretox and Xeomin. The exact product, dose, injection pattern and whether another treatment is relevant should be decided after evaluating the face rather than copying a fixed “Korean technique.”
Eight treatment questions
What to confirm before jaw Botox.
02
Is there baseline asymmetry?
Right and left masseters may not be identical. Facial asymmetry should be assessed before treatment rather than assuming the same plan on both sides.
03
Which botulinum brand?
Newline currently confirms Liztox, Coretox and Xeomin. Ask which product is planned and whether your price quote corresponds to that brand.
04
How many units?
The current price list uses 60U as the square-jaw reference. This page does not claim that every patient requires the same amount or the same units per side.
05
What is the actual goal?
Aesthetic lower-face slimming, clenching concerns and facial asymmetry are not identical goals. Be clear about why you are considering masseter treatment.
06
Is filler or lifting also being considered?
Chin filler or lifting may change facial balance, but extra treatments should only be added when they address a separate, clearly defined concern.
07
What recovery matters to you?
Injection marks, bruising, tenderness or temporary chewing fatigue can occur. Tell Newline if you have important work, photos or travel immediately afterward.
08
What is the final KRW price?
Confirm the brand, total units, area, whether VAT applies and the final payable amount before treatment.
What determines the result
Lower-face width can come from different structures.
Prominent masseter muscle
If the masseter visibly and palpably enlarges during clenching, reducing muscle activity may meaningfully change lower-face width.
Mandibular bone width
Botulinum toxin does not reshape jawbone. If skeletal width is the dominant factor, jaw Botox alone may produce limited visual narrowing.
Soft tissue and facial volume
Fat distribution, skin laxity and facial volume can also influence lower-face shape. These require a different treatment conversation.
Facial asymmetry
Muscle size and activity can differ side to side. Baseline asymmetry should be documented before assessing change.
Clenching / grinding concerns
Masseter activity may be relevant, but dental, bite or TMJ-related symptoms can have multiple causes and should not be reduced to one cosmetic injection.
Aesthetic contour goal
“V-line” can mean different things to different patients. Bring example photos and describe whether you want subtle softening or a more noticeable contour change.

Other brands
Botox, Nabota, Innotox and Daxxify appeared in the legacy content, but they are not presented here as confirmed current Newline jaw-Botox options.
Decision framework
When jaw Botox may — or may not — fit the concern.
More relevant when
- The masseter is visibly prominent when clenching
- You want lower-face softening rather than bone change
- You understand results develop gradually
- You accept that maintenance timing varies
- You want a confirmed Newline botulinum option
Needs careful expectation-setting when
- Jaw width appears partly skeletal
- Baseline facial asymmetry is noticeable
- You already have a narrow or hollow lower face
- You have previous masseter Botox history
- You want a very dramatic transformation
Another discussion may be needed when
- Bone structure is the main cause of width
- Laxity rather than muscle is the main problem
- Volume balance is the main concern
- You have significant jaw pain or dental symptoms requiring evaluation
- You expect one injection to permanently change facial structure
What about more dramatic contouring?
More units or more procedures are not automatically better.
The legacy page encouraged repeat cycles and same-session combinations for a stronger V-line. This Newline version does not prescribe a fixed cycle or automatic combination. If chin filler, lifting or another contour procedure is proposed, ask what specific anatomical issue it is intended to address and whether the additional recovery and cost are justified.
Recovery planning
What to expect after masseter Botox.
Injection marks or bruising
Temporary pinpoint marks, bruising, swelling or tenderness may occur at injection sites. Degree varies by patient and technique.
Chewing changes
Because the masseter is a chewing muscle, some patients may notice temporary fatigue or reduced strength with tough foods. Discuss this if chewing function is important to you.
Exercise, massage and heat
Follow Newline's exact aftercare instructions rather than relying on a universal “4-hour” or “24-hour” rule copied from another clinic.
Travel
There is no blanket same-day-flight guarantee. Tell Newline your departure time before treatment and ask whether any procedure-specific considerations apply.
Results develop gradually
Masseter-related contour change is not immediate. This page does not promise a fixed week-4 or week-8 milestone.
When to contact a clinician
Seek assessment for severe or worsening pain, significant asymmetry, swallowing difficulty, breathing difficulty or other concerning symptoms.
Legacy page cleanup
What was removed or corrected.
No fixed “Korean vs Western” dose rule
The previous 30–50U/side versus 50–80U/side comparison was removed because dose planning should be individualized and units are product-specific.
No fixed week-8 peak / 4–6 month duration guarantee
Onset and duration vary by patient, product, dose and baseline muscle activity.
No permanent baseline-reduction claim
The previous claim that repeated cycles may create lasting baseline atrophy was removed as a universal expectation.
No same-day flight guarantee
Travel advice is now treatment- and patient-specific.
No US savings or USD pricing claims
Current Newline pricing is shown in KRW and no country-level savings claim is made.
No 24-hour recommendation / no-deposit promise
Response time, appointment availability, deposits and booking policies should be confirmed directly.

Frequently asked
FAQ · Jaw Botox in Busan
Does Newline offer jaw Botox for the masseter?
Yes. Square-jaw / masseter Botox is confirmed on Newline's current price list.
What is the current Newline jaw Botox dose reference?
The current price list uses a 60U square-jaw treatment reference. Actual treatment planning should still be individualized.
What are the current jaw Botox prices?
For the 60U square-jaw reference, Liztox is ₩32,000, Coretox is ₩64,000 and Xeomin is ₩150,000. Confirm the final VAT-inclusive amount before treatment.
Which botulinum toxin brands are confirmed at Newline?
The current price list confirms Liztox, Coretox and Xeomin.
Does Newline confirm Botox, Nabota or Innotox for jaw treatment?
Those brands are not part of the confirmed current Newline price information used for this page, so they are not presented here as currently available.
Can jaw Botox change a bony square jaw?
Botulinum toxin acts on muscle activity. If the lower-face width is primarily from mandibular bone rather than masseter muscle, the expected contour change may be limited.
How do I know if my masseter is prominent?
A consultation can assess muscle bulk while you clench, facial asymmetry and how much of the lower-face width appears to come from muscle versus bone or soft tissue.
How quickly will results appear?
This page does not promise a fixed week-by-week result timeline. Muscle-related contour change develops gradually and varies by dose, baseline muscle size and individual response.
How long will jaw Botox last?
No fixed duration is guaranteed. Effect duration varies by product, dose, muscle activity, previous treatment history and individual response.
Will jaw Botox affect chewing?
Temporary changes in chewing strength or fatigue can occur because the masseter is a chewing muscle. Degree varies and should be discussed before treatment.
Can jaw Botox affect the smile?
Unintended effects on nearby muscles are possible with botulinum toxin treatment. Proper assessment and injection planning are important, but this page does not guarantee zero risk.
Can jaw Botox help bruxism?
Masseter Botox may be discussed when clenching or grinding is part of the concern, but this page does not present it as a guaranteed treatment for headaches, TMJ disorders or dental disease.
Can I combine jaw Botox with filler or lifting?
Possibly. Newline confirms chin filler, jaw-related filler categories and multiple lifting devices. Combination treatment should only be used when each component has a clear purpose.
Can I fly the same day?
There is no universal same-day-flight rule. Share your departure time before treatment and ask for treatment-specific guidance.
Who are the doctors at Newline Clinic?
Newline Clinic is led by Chief Director Son Hee-dong, MD, PhD, and Director Seong Jae-min, MD. Both are board-certified plastic surgeons.
