How much is masseter Botox in Korea comes down to two figures the doctor sets after examining your jaw: the units placed in each muscle and the toxin product chosen. Most menus list jaw slimming as one package covering both sides, priced before VAT, and 10% VAT is added at payment. Imported originals usually sit on a higher menu line than Korean-made toxins. Because a narrower outline builds over several weeks and is often maintained with repeat rounds, the real spend is a series rather than a single visit. This page explains how to read the unit count, what published research does and does not support, and which side charges to confirm while staying in Haeundae.

Units per side: the figure that moves the quote
The masseter is a thick chewing muscle, and the dose needed to soften it depends on its bulk. The doctor feels the muscle while you clench, marks the injection points and then decides how many units go into each side. A larger or more active muscle takes more product, which is the main reason two visitors can be quoted very differently for what sounds like an identical treatment.
For scale, a 2019 four-year follow-up study by Shome and colleagues in Plastic & Reconstructive Surgery gave 50 patients 30 units on each side at baseline, with repeat sessions at 12-week intervals for some of them. That is one protocol from one study, not a rule, yet it shows why a figure without a unit count cannot be lined up against one that states it.
Anyone searching how much is jaw Botox in Korea will meet menus that print a single package figure. Ask for the units per side in writing, next to the product name. If one side is visibly larger, the doctor may dose the two sides differently, and the package figure can shift on the day.

Toxin categories printed on a jaw slimming menu
Clinics often split jaw slimming into several lines by product category, each priced separately. The table shows the categories that appear in Korea and where menus tend to place them.
| Category | Example product and maker | Usual menu position |
|---|---|---|
| Imported original | Botox (onabotulinumtoxinA), Allergan | Higher-priced line |
| Imported purified | Xeomin (incobotulinumtoxinA), Merz | Imported tier, often chosen when antibody formation is a worry |
| Korean purified | Coretox, Medytox | Korean tier, non-toxin proteins removed |
| Korean, US-approved | Nabota (prabotulinumtoxinA), Daewoong, sold in the US as Jeuveau | Korean tier |
| Other Korean-made | Hutox, Liztox, Meditoxin and similar | Lower-priced line |
- A lower line does not mean a weaker drug.
- A higher line does not promise a longer result.
- A quote that only says domestic toxin needs the brand named before you agree.

What the research supports before you pay for more rounds
Evidence for cosmetic jaw slimming is thinner than the number of menus suggests. A 2013 Cochrane systematic review by Fedorowicz and colleagues searched widely for randomized or controlled trials of toxin for benign enlargement of both masseters, assessed 23 full-text studies and could include none of them, so it could not draw a firm conclusion on efficacy or safety.
Smaller studies do report change. In the 2024 Thi-Qar study, 19 patients rated their jaw on a visual analog scale before injection and again at 12 weeks, and the authors reported a significant reduction overall. One patient showed no change and one developed a bulge in the muscle when clenching, a reminder that results vary from person to person.
For budgeting, treat the first round as a test. Take photos from the same angle and light before treatment and after about three months, and decide on a second round only once the first has fully settled.

Side charges that sit beside the jaw package
A masseter Botox Korea price on a menu is not always the whole bill. Before the appointment, ask the clinic to confirm each of these in writing.
- Consultation: included in the package or listed on its own.
- Numbing: whether ice or numbing cream is part of the price.
- Review visit: whether a check about two weeks later is free or billed as a new session.
- Extra zones: whether adding the forehead or frown lines is priced separately.
- Tax: menu figures are before VAT, and 10% VAT is added at payment.

Research behind this page
- Botulinum toxin for masseter hypertrophyCochrane Database of Systematic Reviews · 2013 · doi:10.1002/14651858.cd007510.pub3
This Cochrane review screened 683 references and assessed 23 full-text studies but found no randomized or controlled trials eligible for inclusion, leaving the efficacy and safety of masseter toxin without high-level evidence.
- Efficacy of Botulinum Toxin in Treating Asian Indian Patients with Masseter Hypertrophy: A 4-Year Follow-Up StudyPlastic & Reconstructive Surgery · 2019 · doi:10.1097/prs.0000000000005944
50 patients received 30 units per side; muscle size fell about 12% by week 12, and those given repeat doses at 12-week intervals kept a larger reduction at four years.
FAQ
Questions about Botox in Busan
Can I get a firm jaw quote before I arrive in Haeundae?
Usually only an estimate, because the unit count is only set once the muscle has been assessed in person. A clinic can tell you in advance how its package is structured, which toxin products it stocks and that VAT is added at payment. The final figure is confirmed on the day, once the doctor has felt the muscle while you clench. Treat anything sent before the trip as a starting point and ask what would make it change.
Does a higher-priced toxin last longer in the jaw?
Not reliably, because dose, muscle size and your own response shape duration more than the menu line does. Botulinum toxin products generally wear off over roughly three to four months, and jaw results can look longer because the muscle shrinks gradually. Some doctors prefer a purified product for people who have had many rounds. Ask why a particular product is suggested for you rather than assuming cost reflects how long it lasts.
Is the masseter Botox cost in Korea higher with an imported product?
In most cases yes, since imported originals tend to sit on a higher menu line than Korean-made toxins for the same number of units. The gap reflects the product category, not a stronger effect, and each brand has its own unit potency. If you were happy with an imported product at home, asking for it again keeps your past experience a fair reference point for judging the new result.
Which side effects should I leave time for?
Bruising, tenderness and mild swelling at the injection points are common and usually settle within days. Chewing tough food can feel weaker for several weeks. Less often, the smile looks uneven if toxin reaches nearby muscles, or a bulge appears when clenching, as one patient in the 2024 Thi-Qar study experienced. Plan the appointment early enough in the stay that a review can happen before your flight home.
Who should not have masseter injections?
People who are pregnant or breastfeeding, those with a neuromuscular disorder such as myasthenia gravis, and anyone with an infection at the injection site should not be treated. A jaw that looks wide because of bone shape rather than muscle will change little, so toxin is unlikely to be money well spent there. Tell the doctor about blood thinners and any toxin you received elsewhere in recent months.
