How much is masseter Botox in Korea is easier to answer per course than per visit. One session treats both jaw muscles and is listed as a package priced by toxin brand and units per side, before VAT, with 10% VAT added at payment. A visibly narrower lower face often takes two or three rounds about three months apart, so the realistic budget is that package multiplied by the rounds your doctor proposes. If you base the trip in Busan, each return flight or ferry belongs in the plan too. This page shows how to estimate the total and when to stop paying for more rounds.

Why the first round rarely settles the bill
A jaw injection weakens the masseter for months, yet slimming is slow. The muscle shrinks only after weeks of lighter use, so one round often brings a modest change. That is why clinics in Busan usually describe jaw contouring as a plan rather than a single appointment.
Long-term measurements back this up. Shome and colleagues, writing in Plastic & Reconstructive Surgery in 2019, gave 50 Asian Indian patients 30 units per side and tracked muscle thickness by ultrasound for four years. In that study, one round reduced the muscle by about 12 percent at week 12. With a second round the study saw a peak of 26.6 percent at week 24, a third reached 42.52 percent at week 36, and most of that reduction held at four years.
The budgeting lesson is simple: ask at the first consultation how many rounds the doctor expects for your jaw, and price that number. Results vary from person to person, and some people stop after one or two sessions.

Reading a jaw slimming quote line by line
Two figures from two clinics mean little until they describe the same treatment. Whether you ask how much is jaw Botox in Korea at a front desk or look up the masseter Botox Korea price on a menu board, check the brand, the units per side and whether both sides are covered. Prices are normally shown before VAT.
Korean-made toxins such as Nabota by Daewoong, Coretox and Meditoxin by Medytox are usually listed apart from imported Botox by Allergan or Xeomin by Merz, and a strong bite may need more units. Each choice moves the quote, so later rounds should keep the same product and dose.
| Quote item | What it tells you | Question to ask |
|---|---|---|
| Toxin brand | Imported or Korean-made product | Which product is used, and can I see the vial opened? |
| Units per side | The dose each muscle receives | How many units go into each side of my jaw? |
| Sides covered | Whether the figure is for the full jaw | Does the package include both sides? |
| Review visit | Whether a check-up dose is part of the price | Is a two-week review included, and is extra toxin charged? |

Trip costs that sit outside the package
The package pays for the injections, not the journey. Two or three rounds about three months apart can mean another flight into Gimhae International Airport or a ferry crossing each time, plus a night in the city. Many visitors pair sessions with trips already planned.
The visit fits a short stay: the appointment usually takes well under an hour, and flying home the next morning is generally fine. Mild soreness when chewing or small bumps settle within hours to days. Ask for a written record of the brand and units, so a later doctor can continue the course and the masseter Botox cost in Korea stays predictable across trips.

When paying for another round is not worth it
Not every wide lower face is muscle. Width can come from the jawbone or from fat in the lower cheeks, and toxin changes neither. A careful consultation asks you to clench and feels the muscle, sometimes with ultrasound, before proposing a course.
There is also a reason not to keep going by habit. In a 2024 meta-analysis in the Journal of Oral Rehabilitation, Moussa and colleagues pooled studies of jawbone changes after toxin injections. Across the human studies in that review, cortical bone in parts of the jaw was about 6 percent thinner after treatment, with no clear change in bone volume or density. The clinical meaning is uncertain, but it supports stopping once the shape you want is reached.
A course is not appropriate in these situations:
- Pregnancy or breastfeeding
- A neuromuscular condition such as myasthenia gravis
- Infection or an active skin problem over the jaw
- A jaw width that comes mainly from bone or fat

FAQ
Questions about Botox in Busan
Is a listed jaw package priced for one side or both?
Most jaw packages cover both sides in one figure, but some menus list a price per side. Ask whether the units shown are per side or in total, because the two are easy to confuse. A package that looks low may describe one side only, or a smaller dose spread over both. Once two quotes state units per side and the same brand, they compare fairly.
Do I pay again for a touch-up two weeks later?
It depends on the clinic, so ask before the first injection. Some packages include a two-week check and a small top-up if one side looks stronger, while others charge for any extra units. Uneven strength often shows only once the toxin has fully taken hold. If you fly home sooner, ask whether a photo check is possible and what a later top-up would involve.
Will a Korean-made toxin give a weaker jaw result than an imported one?
Not necessarily; Korean-made toxins are licensed products used widely for jaw contouring, and the doctor sets the units for each product. Units are not exactly interchangeable between brands, so the dose is matched to the product rather than copied across. Some people still prefer an imported brand. The practical rule is to keep the same product through one course so the effect can be judged.
How many units does a masseter session usually use?
The dose is set per side from the size and strength of the muscle, so there is no single number for everyone. In the 2019 study by Shome and colleagues in Plastic & Reconstructive Surgery, each side received 30 units of botulinum toxin type A. Clinics may use less for a small muscle or more for a strong bite. Ask for the figure in writing, since unit count is what makes prices comparable.
What is a sensible budget if I only want a small change?
Plan for one round and a review, then decide on a second once the result has settled. A subtle softening of the jaw angle may need fewer units and fewer rounds than full contouring, which lowers the total. Say at the consultation that you want a small change and ask what dose and how many sessions that implies, then multiply from the packages on the price guide.
