How much is masseter Botox in Korea comes down less to one menu line than to what each paid round delivers. Gangnam clinics usually list jaw toxin as a package for both sides, set by the toxin brand and the units placed in each muscle, before VAT, with 10% VAT added at payment. The fee buys an assessment, the injections and a muscle that weakens over the following weeks; any slimmer outline appears slowly. Published evidence for cosmetic jaw slimming is thinner than menus imply, so paying for one round and judging your response before booking the next is a sensible way to spend.

What the jaw fee pays for on the day
Whether you ask how much is jaw Botox in Korea at a Gangnam front desk or read it off a menu, the fee normally bundles a short consultation, the product, the doctor's time and the supplies used to clean and numb the skin. The doctor asks you to clench, feels each masseter and marks its lower, outer portion, away from the zone near the mouth where toxin can alter the smile.
The injecting takes a few minutes per side after ice or numbing cream, and small raised spots usually settle within the hour. Ask whether a review visit about two weeks later is included, because that detail shifts the real figure more than most visitors expect.
- Both sides in one package, or each side priced separately
- Product name, imported or Korean-made
- Units per side, written on the quote

Why two people pay different amounts for the same jaw
Two visitors may ask for the same area and leave with different bills. A thick masseter needs more units than a slim one, an uneven jaw may get a different dose on each side, and treating night-time clenching is a different goal from narrowing the face.
Product choice moves the masseter Botox Korea price as well. Gangnam menus carry imported toxins such as Botox by Allergan and Xeomin by Merz next to Korean-made Nabota by Daewoong and Coretox by Medytox, all approved by the Korean Ministry of Food and Drug Safety. A doctor who explains why a product and dose suit your muscle gives you more for the fee than one who reads out a menu.
| What differs | Effect on the plan | Question to ask |
|---|---|---|
| Thick, strong muscle | More units per side | How many units will each side receive? |
| One side larger | Uneven dose between sides | Is each side dosed and priced on its own? |
| Clenching or grinding | Aim is comfort, not contour | Is the dose set for function or for shape? |

What the research says before you commit to several rounds
Fedorowicz and colleagues reviewed the evidence for the Cochrane Database of Systematic Reviews in 2013. They screened 683 references and read 23 full-text studies, yet none was a randomized or controlled trial against placebo for benign masseter enlargement, so the review could not reach firm conclusions on efficacy or safety.
That is not proof that jaw slimming fails; case series and long clinical use describe a narrower lower face after repeated rounds. It does mean the size and duration of the change are less predictable than a prepaid course suggests. Baker made a related point in a 2016 overview in the Journal of Aesthetic Nursing: evidence on how long facial toxin effects last under different schedules is limited. So pay for one round, judge the outcome from your own photos, then decide on the next.
Guide
Timing paid rounds around a Gangnam stay
Toxin starts to act within days, but the jaw outline changes over several weeks as the muscle is used less. On a short Seoul trip you will usually fly home before seeing much difference; flying the same day is generally acceptable.
Book early in your stay so bruising can fade and a quick review is possible before you leave. Take front and angled photos in the same light before treatment and again a few weeks later. The effect commonly fades over three to four months, so a second round often lines up with a later trip.
Guide
When spending more will not narrow the jaw
Not every wide lower face is muscle. Width from the jawbone or from fat in the lower cheeks does not respond to toxin, and extra rounds add only cost. A doctor who says so at the first visit saves you money.
Jaw toxin is not suitable during pregnancy or breastfeeding, with certain nerve and muscle conditions, or with infection on the area. Common effects are tender spots, small bruises and tired chewing for a few weeks; less often the smile looks uneven, or the area under the cheekbone looks hollow after repeated high doses.

FAQ
Questions about Botox in Gangnam
What does jaw toxin cost when only one side is larger?
An uneven jaw is often dosed differently on each side, so the quote may differ from a standard two-sided package. The doctor feels both muscles while you clench and may place more units on the larger side. Some clinics still charge one package, while others price each side by units used. Ask for the units per side in writing so you can compare with any later round.
Why might a jaw quote change after the assessment?
The menu figure assumes a typical muscle, and the assessment can show that your jaw needs a different plan. A very thick masseter may need more units, a slim one fewer, and the doctor may suggest a different product for your goal. A quote that changes for a stated reason, written down before injection, is normal; one that changes without explanation deserves a question.
Is the masseter Botox cost in Korea worth it for clenching rather than slimming?
Many people treat the masseter mainly for clenching or grinding, and the dose may then be set for comfort rather than outline. The face may still look slightly narrower over time, but that is not the main aim. Say which goal matters more, because it changes where the toxin goes and how much is used. Results vary from person to person.
Does a Korean-made toxin wear off faster in the jaw?
Approved Korean-made and imported toxins both commonly last about three to four months, and individual response varies more than brand. Muscle strength, dose and clenching habits all affect how long the effect holds. Head-to-head evidence between brands is limited, so keeping the same product and dose for a second round makes your own comparison clearer. Results vary from person to person.
What should I record to compare results between paid rounds?
Front and angled photos in the same light, taken before treatment and again several weeks later, give the clearest record of change. Note the product, the units on each side and the date of each round from your quote, plus when chewing felt tired. These notes let the doctor adjust the dose at the next visit instead of starting over.
