How much is masseter Botox in Korea depends less on one visit than on how many rounds you pay for across a year. Clinics usually list jaw toxin as one package for both sides, set by the toxin brand and the units placed in each muscle, before VAT, with 10% VAT added at payment. For someone living in Seoul, the yearly total follows the interval between rounds, which shifts with product, dose, jaw shape and even chewing habits. The site's price guide carries current packages; this page explains what moves them.
Guide
Why the gap between rounds sets the real cost
A jaw package is paid per round, yet what you are buying is months of a slimmer lower face, so the useful figure is cost per month of effect. As nerve signals return, the masseter slowly regains bulk and the jaw widens again. Toxin products are generally described as lasting three to four months, but the masseter is a large, hard-working muscle and timing differs from person to person.
Two people quoted the same masseter Botox Korea price can therefore finish the year with very different totals. One returns as soon as the jaw fills out; another books again only before graduation photos or a wedding. Neither habit is wrong, but they are different budgets, and choosing one before the first injection keeps spending predictable.

Can chewing habits stretch the time between paid rounds?
Wei and colleagues tested this in a 2015 randomized study in Dermatologic Surgery. Ninety-eight patients received 35 units of botulinum toxin type A in each masseter and were split into two equal groups. One group was told to chew with more effort while the masseter was weakened, so the neighboring chewing muscles took over the work. Once the masseter began to recover, both groups were told to chew less.
The guided group took significantly longer to regain masseter bulk, and their other chewing muscles grew thicker, while those of the comparison group stayed about the same or shrank slightly. A longer gap means fewer paid visits a year. It is one trial from one hospital, so ask the treating doctor whether chewing advice suits your bite, and skip it if you have jaw joint pain or clicking.

How units, brand and an uneven jaw move the quote
The dose is set after the doctor feels the muscle while you clench, and it is not always equal on both sides. In a 2023 review in Aesthetic Surgery Journal Open Forum, Wu and colleagues described individual plans for symmetric and asymmetric masseter prominence, and noted that jaw slimming with toxin is widely performed in Asia but not officially approved for it in any country. A stronger muscle on one side can mean extra units, which some clinics bill as an add-on.
Brand is the second lever, and it is where most of the answer to how much is jaw Botox in Korea sits. Menus separate imported products, such as onabotulinumtoxinA from Allergan or incobotulinumtoxinA from Merz, from Korean-made ones such as Nabota from Daewoong and Coretox from Medytox. Imported lines tend to sit higher. Whether a pricier product lasts longer in your jaw is something no menu can promise.
| Quote item | Why it changes the total | What to ask |
|---|---|---|
| Units per side | A thick or uneven muscle may need more toxin | Units on each side? |
| Product | Imported and Korean-made toxins sit on separate lines | Which brand, opened in front of me? |
| Review visit | Some packages include a check, others bill extra units | Is a top-up included? |
| Bundled areas | Adding chin or neck toxin changes the package | Jaw alone or in a bundle? |
| VAT | Menu figures are normally before tax | Is 10% VAT added at payment? |
Guide
When the width is bone or fat, not muscle
Toxin only relaxes muscle. If the lower face looks wide because of bone, cheek fat or loose skin, extra rounds add cost without adding change. A doctor can usually tell by feeling the jaw angle while you bite: a muscle that hardens and bulges tends to respond, a soft or bony width does not.
Ask at the first consultation whether toxin is the right tool and what would be used instead. A clinic that says when not to treat is giving you useful budget information.

FAQ
Questions about Botox in Hongdae
Does a first jaw round cost the same as later ones?
Later rounds are often listed at the same package figure as the first, but the dose inside may change. Some doctors lower the units once the muscle has thinned, while others keep the dose steady to hold the shape. Ask at each visit whether the unit count is changing and whether a smaller package then applies. Writing down units and brand each time makes the next quote easy to check.
What does a jaw toxin package usually include?
A jaw package normally covers both sides, the toxin, numbing cream or ice and a short assessment. What varies is the review visit, extra units for an uneven side and aftercare products. Ask for these in writing before you agree, with the product name and units per side, because a quote that leaves them out can look lower than one that lists everything.
Will I pay for extra units if the jaw still bulges at the check-up?
That depends on the clinic, so settle it before the injection. Some packages include a small top-up at the review if one area still contracts strongly; others charge for every added unit. The check usually happens once the muscle has had a few weeks to soften, so if you are leaving Seoul soon, ask whether the review can be moved earlier.
Is VAT part of the masseter Botox cost in Korea shown on a menu?
Usually not: menu figures for jaw toxin are generally shown before VAT, and 10% VAT is added at payment. Some clinics print the tax-inclusive total on the receipt only. When you compare two quotes, check that both are stated the same way, before or after VAT, so the comparison is fair. Keep the receipt with the units and product written on it for your next visit.
What risks come with masseter injections?
Common effects are mild tenderness, small bruises and a tired feeling when chewing tough food for a few weeks. Less often, toxin spreads to nearby muscles and changes the smile for a while, or one side slims more than the other. People who are pregnant, breastfeeding or living with a neuromuscular condition should not have it. Results vary from person to person.
What happens to my face if I stop jaw toxin after a year?
The masseter gradually regains its earlier bulk as the last round wears off, so the jaw drifts back toward how it looked before treatment, slowly rather than suddenly. If you are moving away from Seoul or pausing for a pregnancy, tell the doctor so the final round is planned around it. Starting again later is possible after a fresh assessment.
