What Is Jaw Botox?

One injection for the jawline you keep asking about.

Jaw botox (masseter botox) relaxes the masseter — the chewing muscle that, when overdeveloped, squares off the lower face. As the muscle quietly shrinks over 2–6 weeks, the jaw tapers into a softer V-line.

It treats a wide or square jaw, jaw tension and clenching, and teeth grinding (bruxism) at the same time. At JRYN Seomyeon we run four brand tiers — Korean Newlux at ₩15,000 through to Allergan at ₩139,000 — and match the dose to your muscle, never to a fixed menu. The most common mistake we correct is over-treatment, not under-treatment.

How It Works

The science, without the hype.

Understanding the mechanism helps you set realistic expectations — and see why dose matters more than brand.

01

The masseter muscle

A square muscle linking cheekbone to lower jaw. Overdeveloped by chewing, clenching or genetics, it widens the jawline.

02

Precise injection

Dr. Lee places small doses at exact anatomical points — typically 25–50 units per side, scaled to your muscle, not a default.

03

Gradual slimming

With less use, the muscle shrinks over 2–6 weeks. The jaw looks narrower and softer — the V-line builds in, never overnight.

04

Maintenance

Results hold 4–6 months. The first repeat is usually at 4 months; later sessions stretch further as the muscle stays smaller.

Jaw Botox Pricing

Four tiers, one honest goal.

Korean and imported brands are all clinically safe in licensed hands. The difference is cost, onset and how long it lasts — we'll tell you which actually suits you.

Brand Price · 50u Best for Duration
Newlux Korea · Value ₩15,000 First-timers, maintenance, budget-aware 3–4 months
Coretox Korea · High-Purity ₩35,000 Long-term users (lower antibody resistance) 4–5 months
Dysport Imported · France ₩90,000 Faster onset, wider diffusion 4–5 months
Allergan Imported · USA · FDA ₩139,000 Longest track record, premium choice 5–6 months

Guide prices per session for foreign patients. 3-session courses from ₩40,000 (Newlux). Jawline + salivary/temporalis combo (Allergan) ₩270,000. Korean medical advertising rules limit fixed online pricing — message us for an exact quote before you travel.

Honest Candidacy

Who it suits — and who should wait.

A good fit if you…

  • Have a visibly wide or square jaw from a strong masseter
  • Clench or grind your teeth, or wake with jaw tension
  • Want a softer lower face without surgery or downtime
  • Are realistic that the V-line builds over weeks, not days

Better to wait if you…

  • Have a wide face mainly from bone structure, not muscle
  • Are pregnant or breastfeeding
  • Want a dramatic change in a single visit — it won't be instant
  • Have sagging skin that slimming alone could accentuate (lifting may suit better)

After your treatment

  • Walk out and carry on — no downtime, no bandages, fine to fly the same day
  • Skip vigorous exercise, alcohol and saunas for about 24 hours
  • Avoid pressing or massaging the area for the first night
  • Chewing may feel slightly different for a week as the muscle relaxes

Possible side effects

  • Mild tenderness or a small bruise at injection points
  • A brief, temporary chewing fatigue while the muscle adjusts
  • Rare, dose-dependent asymmetry — minimised by careful placement
  • We review you on WhatsApp after you fly home, in your language

Your Injector · Founder

Jaw botox is about the right units, not the most.

A heavy masseter doesn't always need a heavy dose. I'd rather you come back for a small top-up than walk out unable to chew comfortably. Over-treating is the most common mistake I correct.

  • Board-certified dermatologist · MD, Inje University College of Medicine
  • Founder, JRYN Dermatology (2007) · masseter botox injected thousands of times
  • Verified-dose products only · Korean MFDS & FDA-approved brands
  • A calm, unhurried consultation — your dose is planned, not guessed

Jaw Botox FAQ

Good to know.

At JRYN Seomyeon, jaw botox runs from ₩15,000 (Korean Newlux, 50u) to ₩139,000 (Allergan, 50u), with Coretox at ₩35,000 and Dysport at ₩90,000 in between. A 3-session course starts from ₩40,000. Your exact quote depends on muscle size and brand — we confirm it free in consultation or over WhatsApp.

The slimming is gradual. Most people notice a softer jawline at 2–4 weeks as the masseter shrinks, with the full effect around 6 weeks. It's not an instant change — that gradual onset is exactly what keeps the result looking natural.

It's a few quick injections with a fine needle — most patients describe a brief pinch. There's no downtime: you can return to work, sightseeing, or a flight the same day. We simply ask you to skip alcohol, hard exercise and saunas for about 24 hours.

Often, yes. By relaxing the masseter, jaw botox can ease clenching, grinding (bruxism) and the morning jaw ache that comes with them — many patients come for the slimming and stay for the comfort. We'll assess whether your tension is muscular during consultation.

All four are safe in licensed hands; the difference is cost, onset and longevity. Newlux suits first-timers and maintenance, Coretox suits long-term users, Dysport offers faster onset, and Allergan has the longest track record. We recommend based on your goal and history — not on what costs most.

Yes. Jaw botox is typically done the same day, right after your consultation, in a single 10-minute treatment. Message us your travel dates and a few photos on WhatsApp beforehand and we'll have a plan ready when you arrive in Seomyeon.
