Jaw Botox Cost in Korea: Seoul Price Guide

Quick answer: Jaw Botox cost in Korea is typically about KRW 50,000–150,000 (roughly US$36–107) with a Korean toxin and about KRW 150,000–350,000 (US$107–250) with imported Botox or Xeomin in Seoul in 2026. Units, brand and repeat schedule decide your real budget, since most people repeat masseter Botox 2–3 times in the first year.

Jaw Botox, also called masseter Botox, is an injection of botulinum toxin into the masseter, the large chewing muscle at the angle of the jaw. Relaxing this muscle can slim a square-looking lower face over several weeks and may ease clenching-related tension. It is one of the most requested treatments for a V-line look in Korea.

The typical 2026 Seoul market ranges are below. They are approximate, per session for both sides, converted at about KRW 1,400 to US$1.

A 10% VAT is often added to cosmetic procedures. For current figures and promotions, see the current price list.

The masseter is a large muscle, so jaw Botox uses more units than small areas such as the frown. That magnifies the price difference between brands.

• Korean toxins such as Nabota and Botulax are produced domestically and are widely used, which keeps the cost down. Many people choose them for the jaw.
• Imported options include Botox by Allergan and Xeomin in Seoul. Xeomin contains no complexing proteins, which some doctors consider for people who have repeated treatments over many years.

Both are commonly used in Seoul. Your history and the doctor’s assessment should guide the brand. For a deeper look, read Korean Botox vs Imported Botox.

• Units: a strong, thick masseter may need more product. The doctor checks muscle size by touch while you clench.
• Brand: Korean vs imported, as above.
• Combined areas: adding salivary gland or trapezius Botox, or forehead and frown, changes the total.
• Follow-up: ask whether a check-up or adjustment visit is included.
• VAT: confirm whether the quote includes it.

Be cautious with comparisons: one clinic may quote for a standard dose and another for a higher dose. Compare the same brand and approximate units.

Botox starts to work within about 3–7 days, but visible slimming of the jaw is gradual because the muscle needs time to reduce in bulk. Many people notice a change after about 2–6 weeks. Jaw Botox usually lasts longer than the typical 3–4 months seen in the forehead.

1. First session: establishes your response and dose.
2. Second session: often a few months later, as the muscle begins to recover.
3. Third session (if needed): helps maintain the slimmer contour.
4. Maintenance: many people can then space treatments further apart, as the doctor advises.

Because the masseter gradually adapts, the cost per year often falls after the first year. The doctor will avoid over-treatment and adjust timing to your response.

A wide lower face can come from muscle, bone structure, fat or a short chin. The right treatment, and therefore the right budget, depends on the cause.

• Bulky masseter muscle: jaw Botox, the most affordable option.
• Short or receding chin: chin filler in Seoul lengthens the profile for a V-line effect; typically KRW 150,000–500,000 for 1–2cc. See chin filler cost in Korea.
• Small fat pockets under the jaw: double chin injections or other fat-dissolving injections, typically KRW 50,000–200,000 per session.
• Mild laxity along the jawline: a device such as InMode in Hongdae may help with tightening and small fat pockets.

Many people combine jaw Botox with chin filler for a balanced V-line. See Jaw Botox vs Chin Filler for the full comparison.

Jaw Botox is very trip-friendly. You can usually return to sightseeing immediately.

• Small injection marks fade within hours; bruising is uncommon.
• Some people feel mild chewing fatigue with tough foods for a few weeks.
• Avoid massage, saunas and pressing on the jaw for about 24–48 hours.
• Flying the next day is usually fine.

Jaw Botox is not recommended during pregnancy or breastfeeding. Tell the doctor about neuromuscular conditions, dental issues or medications. Results vary from person to person.

Hongdae is easy to reach: Hongik Univ. Station is on Line 2, the Gyeongui–Jungang Line and the AREX Airport Railroad, with direct trains to Incheon and Gimpo airports, so a short jaw Botox appointment can fit on an arrival or departure day. Many clinics in the area have English- or Japanese-speaking staff and take consultation requests by WhatsApp or KakaoTalk, so send photos of your face and your travel dates in advance.

Before you book, confirm who performs the injections, the toxin brand, the number of units and whether VAT is included. Compare quotes with the current Hongdae clinic price list, and read about Botox in Seoul, Xeomin in Seoul and dermal fillers in Seoul. Leave a buffer before photos or events, since slimming takes a few weeks.

Jaw Botox for both masseters typically costs about KRW 50,000–150,000 in Seoul with a Korean toxin and about KRW 150,000–350,000 with imported Botox or Xeomin in 2026. The total depends on units, brand and whether 10% VAT is included. Ask the clinic to confirm the brand and dose in writing.

The toxin starts working within about 3–7 days, but the visible slimming is gradual because the muscle shrinks with less use. Most people notice a change after about 2–6 weeks. If you have an event, plan jaw Botox at least a month ahead for the best effect.

Some people notice mild fatigue when chewing tough or chewy foods for a few weeks after treatment. This is usually temporary as you adapt. The doctor adjusts the dose to your muscle size to balance slimming with comfort. Tell the doctor if you clench or grind your teeth.

When the dose and placement are right, jaw Botox usually gives a natural slimming effect. Over-treatment, or treatment in people with lax skin, may make the lower face look less supported. That is why the doctor assesses muscle size and skin laxity first, and may suggest lifting treatments for people with laxity.

Yes. Jaw Botox is commonly combined with forehead or frown Botox, chin filler, skin boosters or lifting devices. Filler may cause swelling for 2–3 days, so plan around flights and photos. The doctor will set the order and amounts and confirm the total price before treatment.
