If you have been searching for how much does masseter botox cost while planning a trip to Seoul, you have probably noticed answers vary wildly — anywhere from $30 to $1,200 depending on country and brand.
That spread is confusing, especially when you also need to weigh procedure quality and doctor experience.
For first-time international patients asking how much does masseter botox cost in Korea, the treatment is often the entry point into Korean aesthetic care. It slims the lower face, softens a square jawline, and helps with bruxism — from a 5 to 10 minute injection session.
Here at Relieve Clinic in Apgujeong, we understand these concerns deeply. Our philosophy is simple: “Beauty is perfected in comfort.” We focus on minimizing pain and providing personalized injection plans rather than pushing unnecessary upgrades, so first-time patients can make calm, informed decisions.
There is one quiet variable that decides whether masseter botox produces a sharper V-line or a flat, sagging lower face. We will reveal exactly what that is near the end of this guide — so keep reading.
Understanding How Masseter Botox Works
The masseter is one of the strongest muscles in the human body. When it is overdeveloped — from genetics, chewing habits, or teeth grinding — the lower face takes on a square, angular appearance.
Masseter botox uses botulinum toxin to partially block nerve signals to this muscle, gradually reducing its volume through a process called muscle atrophy.
Because the goal is to shrink a strong muscle rather than smooth a wrinkle, the treatment requires higher doses than forehead or crow’s feet botox.
The typical range is 20 to 40 units per side, depending on muscle size, gender, and the look you want. Women generally need around 25 to 35 units per side; men often require 30 to 50 units per side.
How Much Does Masseter Botox Cost in Seoul vs Western Markets
The most direct answer to how much does masseter botox cost depends almost entirely on the brand of toxin and the country you receive treatment in. Seoul is one of the most competitive markets in the world for this procedure, with domestic Korean toxins priced far lower than imported alternatives.
| Brand & Origin | Typical Seoul Range (Both Sides) | US / UK Equivalent |
| Domestic Korean (Nabota, Coretox, Botulax) | $30 – $80 USD | $300 – $600 USD |
| Imported (Allergan Botox, Xeomin) | $150 – $300 USD | $500 – $1,200 USD |
| Premium imported with sedation add-on | $250 – $400 USD | $800 – $1,500 USD |
One critical 2026 update: the 10% VAT refund for foreign aesthetic patients ended on January 1, 2026. The quoted price plus 10% VAT is now your final out-of-pocket cost, with no airport refund available.
So when you compare how much does masseter botox cost across clinics, always confirm whether the menu price already includes VAT.

What Actually Happens During Your First Visit
If you have never had masseter botox before, the procedure timeline is shorter than most first-time patients expect. Here is what a typical Apgujeong boutique-clinic visit looks like:
- Consultation (10–15 min): The doctor reviews your medical history, palpates your masseter to measure muscle volume, and discusses your aesthetic goals.
- Marking (3–5 min): Safe injection zones are mapped to avoid the risorius (smile muscle) and major facial nerves.
- Numbing (optional, 5–10 min): A topical cream or ice pack is applied for sensitive patients.
- Injection (5–10 min): Usually 3 to 5 points per side using a fine 30-gauge needle.
- Aftercare brief: Avoid intense exercise, alcohol, and saunas for 24 hours.
The slimming effect is gradual. Muscle tension relaxes within the first week, visible jaw narrowing appears around weeks 2 to 4, and peak V-line contouring shows at weeks 6 to 8. Results generally last 3 to 6 months.
The Critical Factor We Promised to Reveal
Here is the quiet variable: injection depth and lateral placement matter far more than the brand of toxin. The masseter has multiple layers, and the deep belly is what creates the square jawline appearance.
When toxin is placed too superficially or too close to the risorius, two problems can occur — uneven smile movement, or excessive softening that creates a flat, sagging lower face instead of a clean V-line.
This is why two patients receiving the same brand, the same total units, and the same clinic chain can walk away with very different outcomes.
At Relieve Clinic, every first-time masseter botox patient meets directly with our director, Dr. Park Tae-oh, who maps the deep belly of the muscle through palpation and recommends a dose distribution tailored to your face — not a one-size-fits-all template.
Planning Your Visit to Seoul
Masseter botox is a same-day procedure with effectively zero social downtime — most patients return to work, sightseeing, or dining the same evening.
If you are flying into Seoul specifically for aesthetic care, we recommend scheduling the consultation and injection on day one or two of your stay so any minor swelling subsides before your return flight.
Because the slimming effect develops over 6 to 8 weeks, do not judge results on the day you leave Korea. Our English-speaking coordinators provide written aftercare instructions and can offer follow-up consultations via message if you have any concerns once you are home.

Is masseter botox painful?
Most patients describe the sensation as a brief pinch lasting only a few seconds per injection point. Korean boutique clinics typically offer topical numbing cream or an ice pack on request, which makes the procedure tolerable for the vast majority of first-time patients.
How soon can I fly home after masseter botox in Korea?
You can fly the same day if needed. There are no documented contraindications to air travel after masseter injections, though most clinics suggest waiting 24 hours so any minor swelling at the injection points has time to settle.
Will my face look strange or asymmetric after treatment?
When the muscle is mapped properly and the dose is distributed across the deep belly rather than the superficial layer, the result looks natural and symmetric. Asymmetry usually traces back to inconsistent injection depth, which is why doctor experience and individualized planning matter more than brand selection.
Dr. Park Tae-oh is the founder and director of Relieve Clinic Seoul in Apgujeong, Gangnam, where he performs consultation and treatment personally. His work centers on reducing discomfort during aesthetic dermatology, drawing on more than 30,000 clinical cases. In June 2026 he demonstrated periorbital radiofrequency technique using XERF at Cynosure Lutronic Academy Korea.
