Jaw Botox Price in Korea: Masseter Treatment Cost
Jaw Botox, also called masseter Botox or square-jaw Botox, is one of the treatments Korea is best known for. It softens a wide, square lower face by relaxing the chewing muscle, and it is quick enough to fit into a short trip. This guide explains how masseter Botox is priced in Korea, what the current options cost at a clinic in Seomyeon, Busan, and what to expect from the result, so you can judge a quote with confidence.
Quick answer: Jaw Botox price in Korea depends on the number of units, the brand of toxin and whether it is combined with a fat-dissolving contour injection. At a clinic in Seomyeon, Korean-made masseter toxin is offered in packages from KRW 99,000 (with an 18cc power contouring injection); a 50U Korean jaw Botox first-visit trial is KRW 9,900. Prices exclude 10% VAT. Slimming develops over about 4–8 weeks and usually lasts 3–6 months.
What is jaw Botox and how does it work?
The masseter is the strong muscle at the back of the jaw that you feel when you clench. In people who chew a lot, grind their teeth or simply have naturally large muscles, it can make the lower face look wide and square. Botulinum toxin type A injected into the masseter temporarily blocks the nerve signal to the muscle. With less use, the muscle gradually reduces in bulk, giving a softer, slimmer jawline.
Because the change comes from the muscle shrinking, it appears slowly: lines elsewhere soften within days, but jaw slimming takes weeks.
How much does jaw Botox cost in Korea?
At a clinic in Seomyeon, current listed options include:
- Korean jaw Botox 50U : KRW 9,900 – first-visit single-session trial offer, availability confirmed when you book

Imported toxin (such as German Xeomin) or a specific Korean brand (Nabota, Coretox, Liztox) for the jaw is quoted by dose after consultation.

What affects the price
Units
The dose depends on the size and strength of your masseter. 50U is a common starting point. Men, people who grind their teeth or chew gum often may have larger muscles and need a different plan. A very cheap quote with an unstated dose may mean fewer units.
Brand
Korean-made toxins are usually the lower-cost option; imported brands typically cost more. All are botulinum toxin type A and work the same way. Protein-free toxins (Xeomin, Coretox) may be suggested if you have toxin often.
Fat, muscle or both
A wide lower face often has two causes: fat and a strong chewing muscle. Toxin slims muscle but does not remove fat; a contour injection reduces fat but cannot shrink muscle. That is why many Korean packages pair the two. If your width is mostly one or the other, a single treatment may be enough and cheaper.
Extra areas
A 3-area plan adds the temporalis (temple muscle) and parotid glands for an overall smaller-looking face, at a higher price than masseter alone.
Who jaw Botox suits, and who should choose something else
Jaw Botox tends to suit you if your jaw hardens noticeably when you clench, your lower face looks square from the side angle, or you grind or clench your teeth. It is less helpful if:
- Fullness comes mainly from fat. A contour injection or ONDA targets fat.
- The jawline is soft from loose skin. Lifting such as Shurink Universe or Ultherapy is more relevant.
- Width is from bone structure. Toxin will not change bone.
It is not suitable during pregnancy or breastfeeding, with a neuromuscular condition such as myasthenia gravis, infection at the site or an allergy to any ingredient. Tell the doctor about blood thinners.
What happens on the day
- Consultation. The doctor feels the masseter while you clench and relax, checks both sides and confirms the dose and price.
- Marking. Injection points are marked; numbing is usually not needed.
- Injection. A fine needle delivers measured doses into each masseter in a few minutes.
- Done. You can go straight back to sightseeing.
Results and timeline
- First 1–2 weeks: the muscle starts to relax; chewing hard foods may feel slightly tiring.
- Weeks 4–8: slimming becomes visible as the masseter reduces.
- Months 3–6: the muscle gradually regains bulk; repeat treatment maintains the shape.
Judging the result after a few days is too early. Many people repeat it regularly, and the dose can change as the muscle gets smaller. Results vary from person to person.
Side effects and aftercare
- Small bumps, redness or bruising at injection points usually settle within hours to a few days.
- Mild chewing fatigue for a few weeks is common.
- Rarely, asymmetry or a change in smile can occur, which fades as the effect wears off.
- On the day, avoid rubbing or massaging the jaw, saunas and jjimjilbang, and strenuous exercise.
Very frequent top-ups at high doses are not recommended, because they may raise the chance of the body forming antibodies over time. Treatment every 3–6 months, once movement returns, is the usual rhythm.
Planning around a trip or event
There is no downtime, so jaw Botox fits easily into any stay. For a wedding or photoshoot, have it about 4–8 weeks before so slimming has time to show. The Seomyeon clinic is about 3 minutes from Seomyeon Station Exit 7 and open Monday to Friday 10:00–20:00 and Saturday 10:00–16:00 KST, closed on Sundays.
Frequently asked questions
