Incheon AirportHow much is jaw botox in Gangnam, and what does it do?
₩29,000 ($21 USD) buys 50U of masseter jaw botox at RE:BERRY in Gangnam, Seoul — botulinum toxin injected into the masseter, the muscle you clench to chew, so the overdeveloped muscle gradually relaxes and reduces. The lower-face contour looks slimmer over 4-8 weeks, with onset from 1-2 weeks and the effect lasting 4-6 months. Because a wide lower face can come from muscle or from soft-tissue fullness, the physician palpates your clenched jaw first — jaw botox helps only when the width is muscle.
Effects & Progress
Effects & Progress
Botulinum toxin relaxes the overdeveloped masseter so it is used less, and — like any under-used muscle — it gradually reduces in size, softening a square lower-face contour.
Injections take only minutes with no wound. Makeup and daily life — including travel — are fine the same day. The contour has not visibly changed yet.
The masseter begins to relax and you may notice mild, temporary chewing fatigue. This settles as you adjust, and normal eating is not prevented.
The main slimming phase — the masseter reduces from reduced use and the square lower-face contour softens visibly over roughly 4-8 weeks. Response speed varies by individual.
Maintenance period. The muscle-relaxing effect lasts 4-6 months before the masseter regains activity; RE:BERRY will guide the repeat interval that suits your jaw.

Effects & Progress
A wide, square lower face is often driven by an overdeveloped masseter, the muscle that closes the jaw when you chew. Jaw botox delivers botulinum toxin that reduces the nerve signal telling the masseter to contract, so the muscle is used less. As with any under-used muscle, it undergoes gradual disuse reduction, and as the masseter reduces the lower-face contour softens — the change is anatomical, coming from your own muscle, with nothing removed or implanted.
The result develops on a muscle's timeline, not an injection's. The relaxing effect begins in roughly 1-2 weeks, and the visible slimming builds over about 4-8 weeks as the masseter reduces from reduced use. This gradual arc is why guests traveling for a specific date are told to expect the contour to develop over the two months after the session, not within the same week. Response speed and magnitude genuinely vary by individual.
Jaw botox is a maintenance treatment, and we say so plainly. The muscle-relaxing effect typically lasts 4-6 months, after which the masseter gradually regains activity and the contour softens back toward baseline. Many guests schedule a repeat before that happens, often two to three times in the first year and then less frequently as the muscle stays relatively reduced. The physician sets the interval from how your own muscle responds, not from a fixed calendar.
Jaw botox is not for every wide jaw. Because it acts only on muscle, a lower face that is wide from soft-tissue fullness or skeletal shape will not respond, so the physician palpates your clenched jaw before any injection — a firm bulge that hardens when you bite is masseter muscle, while fullness that stays soft is fat and looseness is skin. When the width is not muscle, a fat- or skin-directed path fits better, and temporary chewing fatigue in the first weeks is discussed openly as part of the intended muscle relaxation.

What Jaw Botox in Gangnam Delivers — and How the Result Builds
- Slimmer lower-face contour without surgery: relaxing the overdeveloped masseter lets the muscle reduce gradually, softening a square jaw over 4-8 weeks with no incision and no recovery room
- Published price you can verify before booking: masseter jaw botox 50U is ₩29,000 ($21 USD) at RE:BERRY Gangnam, and the bill matches that figure with no add-on charges
- Muscle-versus-fat check comes first: the physician palpates your clenched jaw so jaw botox is only recommended when your lower-face width is genuinely muscle, not soft-tissue fullness
- Support for jaw clenching and teeth grinding: many guests who over-use the masseter report less jaw tension once the muscle relaxes, a comfort benefit that is discussed openly but never promised
- Same physician from the palpation exam through the injections to your review — your jaw botox case in Gangnam is never passed to another practitioner mid-course
- Clear expectations set at consultation: onset in 1-2 weeks, full contour change by 4-8 weeks, and an effect that lasts 4-6 months before a repeat session is considered
| Timeline | What to Expect |
|---|---|
| Injections take only minutes and leave no wound — makeup, flying, and dinner reservations are all fine the same day | |
| The masseter begins to relax and you may feel mild, temporary chewing fatigue; the contour has not visibly changed yet | |
| The muscle reduces gradually from reduced use, and the slimmer lower-face contour becomes visible over this window | |
| The muscle-relaxing effect wears off over 4-6 months as the masseter regains activity; a repeat session is considered to maintain the contour |
Jaw Botox vs Contour Injection vs InMode FX — Choosing a Lower-Face Path in Gangnam
| Criteria | Jaw (Masseter) Botox (RE:BERRY Gangnam) | Contour Injection (fat-targeting) | InMode FX (RF) |
|---|---|---|---|
| Target tissue | Overdeveloped masseter chewing muscle | Localized subcutaneous fat | Skin laxity in the dermis, radiofrequency |
| What it does | Relaxes the muscle so it gradually reduces in size | Breaks down small pockets of fat under the skin | Heats the dermis to tighten and firm skin |
| Best when the width is | Muscle — a firm bulge that hardens when you clench | Fat — soft fullness that stays soft when you clench | Loose or crepey skin more than volume |
| Onset | 1-2 weeks to begin, contour by 4-8 weeks | Gradual over several weeks per session | Builds over weeks to a few months |
| Duration | 4-6 months, then a repeat is considered | Fat reduction is longer-lasting once achieved | Collagen effect builds and is maintained periodically |
| Sessions needed | Single session, repeated to maintain | Often a short series | Often a short series |
| Downtime | None — same-day makeup and flights | Mild swelling possible for a few days | Minimal, brief redness possible |
| Published price | ₩29,000 ($21 USD) / masseter 50U | Consultation required | Consultation required |
Why This Matters
These three are not interchangeable because they act on different tissue: jaw botox relaxes the masseter muscle, contour injection targets fat, and InMode FX heats the dermis to firm skin. A wide lower face can come from any of the three, which is why the physician at RE:BERRY Gangnam palpates your clenched jaw before recommending one — jaw botox helps only when the width is muscle.
Seoul pricing is part of why lower-face contouring in Gangnam draws medical travelers. RE:BERRY publishes masseter jaw botox 50U at ₩29,000 ($21 USD), a figure that is unusually transparent for a treatment often quoted only after an in-person visit elsewhere. The published rate lets international guests plan before they fly.
In KHIDI's 2025 international patient survey, 39.7% of English-speaking patients put the doctor's credentials first when choosing a Korean clinic. At RE:BERRY the physician who palpates your clenched masseter is also the one who maps the injection points, places the dose, and reads your review — no handoff between stages.

The Evidence Behind Masseter Botulinum Toxin for Jaw Slimming
Masseter jaw slimming works by chemical denervation: botulinum toxin blocks the release of acetylcholine at the neuromuscular junction of the masseter, the muscle that closes the jaw when you chew. With reduced signaling the muscle contracts less, and — as with any muscle that is used less — it undergoes gradual disuse reduction, so the lower-face contour slims over weeks, not immediately. Imaging studies confirm this mechanism: ultrasonographic measurement of masseter thickness after a single injection documented a significant decrease in muscle thickness that developed over the weeks following treatment.
Kim NH, Chung JH, Park RH, Park JB. The use of botulinum toxin type A in aesthetic mandibular contouring. Plast Reconstr Surg. 2005;115(3):919-930. doi:10.1097/01.PRS.0000153236.79775.A0
Dose-response and durability have been studied in controlled trials. A randomized, double-blind, placebo-controlled study of botulinum toxin for benign masseter hypertrophy demonstrated measurable reduction in masseter thickness and lower-face width, with the effect building over the first weeks and then waning over several months as muscle activity returned — the basis for the stated 4-6 month duration and the need for repeat sessions to maintain the contour. Systematic review of the pooled evidence likewise reports consistent thickness reduction while noting that response magnitude and duration vary between individuals.

The evidence also frames the practical limits communicated at RE:BERRY Gangnam. Because the treatment acts only on muscle, a wide lower face driven by soft-tissue fullness or skeletal shape will not respond — hence the physician's palpation of the clenched jaw before any injection. Temporary chewing fatigue in the first weeks reflects the intended reduction in bite force and settles as patients adapt. Separate work on botulinum toxin for masseter over-activity has reported reductions in clenching and grinding symptoms for some patients, so RE:BERRY frames any jaw-tension benefit as supportive and individual — never a promised dental treatment.

Questions International Guests Ask About Jaw Botox in Gangnam
How much does jaw botox cost in Gangnam, Seoul in 2026?
₩29,000 ($21 USD) covers masseter jaw botox 50U at RE:BERRY Gangnam — the regular rate, published before you book with no add-ons. The 50U is the domestic-standard dose for the masseter, split between your left and right jaw. The botox price page lists the full line-up.
How do I know if my wide jaw is muscle or fat?
Clench your teeth and press along the angle of your jaw. If a firm bulge hardens under your fingers when you bite, that is masseter muscle and it responds to jaw botox. If the fullness stays soft when you clench, it is fat or skin, which botox does not treat. At RE:BERRY Gangnam the physician performs this palpation for you at consultation, because getting the tissue type right decides whether jaw botox will actually work.
How does masseter botox slim the jaw?
Botulinum toxin injected into the masseter reduces the nerve signal that makes the muscle contract, so the muscle is used less and gradually reduces in size — the same way any under-used muscle shrinks. As the masseter reduces, the square lower-face contour softens. The change is gradual because muscle takes weeks to reduce, not because the injection is repeated.
When will I see results from jaw botox, and is it immediate?
It is not immediate. The muscle-relaxing effect begins in about 1-2 weeks, and the slimmer contour becomes visible as the masseter reduces over roughly 4-8 weeks. If you are traveling for a specific date, plan for the contour to develop over the two months after your session — do not expect a change the same week.
How long does jaw botox last?
The muscle-relaxing effect typically lasts 4-6 months, after which the masseter gradually regains activity and the contour softens back toward baseline. Many guests schedule a repeat session before that happens to maintain the slimmer contour. This is a maintenance treatment, not a permanent one.
Will my chewing feel weaker after jaw botox?
You may notice mild chewing fatigue in the first weeks — for example, tiring a little sooner on tough or chewy foods — because the masseter is intentionally relaxed. This is temporary and eases as you adjust, and normal eating is not prevented. It reflects the same reduction in bite force that produces the slimming effect.
Can jaw botox help with teeth grinding or jaw clenching?
Relaxing an over-active masseter can ease jaw clenching and grinding tension for some people, and some guests report less jaw fatigue and tightness afterward. We frame this as a supportive, individual benefit, never a promised outcome — it cannot be promised for everyone, and jaw botox is not a substitute for dental evaluation of the underlying cause. Tell the physician at consultation if grinding relief is your main goal.
How often should I repeat jaw botox?
Because the effect lasts about 4-6 months, most guests who want to keep the slimmer contour repeat the treatment two to three times over the first year, then often less frequently as the muscle stays relatively reduced. The physician at RE:BERRY Gangnam sets your interval from how your muscle responds, without a fixed calendar.
What if my two sides of the jaw are different in size?
Mild left-right asymmetry of the masseter is common and normal. The physician plans the 50U so the stronger side may receive slightly more, aiming for a balanced result over a simple even split of the dose. Perfect symmetry cannot be promised, but the goal is to even out a visible difference, and any residual asymmetry is reviewed at follow-up.
Is jaw botox painful, and is there any downtime?
Most guests describe the injections as brief pinches more than real pain, and the whole set takes only minutes. There is no wound to bandage and no downtime — makeup, meals, flights, and sightseeing are all fine the same day, which makes jaw botox easy to fit into a short Seoul itinerary.
Who should not have jaw botox?
Jaw botox is not scheduled during pregnancy or breastfeeding, for people with certain neuromuscular conditions, or when the lower-face width is soft-tissue fullness, not muscle. The physician at RE:BERRY Gangnam screens for these at consultation and will recommend a fat- or skin-directed path instead when jaw botox is not the right fit.
Can I fly the same day, and how should I time it with my trip?
Yes — there is no downtime, so a same-day flight is fine after jaw botox. Because the contour change develops over 4-8 weeks, the practical tip is to have the treatment early in a longer trip or on a first visit, and see the slimmer result build after you return home. A brief follow-up on WhatsApp covers your progress.
How do I book jaw botox in Gangnam as a foreign visitor?
Message RE:BERRY on WhatsApp with your travel dates and photos — a coordinator replies in English as soon as possible, confirms the ₩29,000 ($21 USD) masseter 50U rate in writing, and reserves a physician slot. The clinic is reservation-only for international guests, staff interpreters cover 5 languages, and the palpation exam plus injection fit into a single visit. See the full botox in Gangnam guide.
Where exactly is the clinic, and how do I get there from Gangnam Station?
RE:BERRY sits inside KI Tower on Gangnam-daero, a 2-minute walk from Gangnam Station Exit 10 on Seoul Metro Line 2 — 45-60 minutes from Incheon Airport by AREX plus subway or by direct taxi. Being steps from the station means your jaw botox appointment slots cleanly between Gangnam sightseeing, dining, and shopping.

Science Masseter botulinum toxin for jaw slimming — peer-reviewed references
Masseter jaw slimming rests on a documented mechanism and controlled outcome data. Kim (2005) established botulinum toxin type A for aesthetic mandibular contouring, using ultrasonographic measurement to show masseter thickness decreasing over the weeks after a single injection. Bite-force and repeat-injection work (Kim 2009) quantified the intended, reversible muscle-weakening that underlies both the slimming effect and the temporary chewing fatigue reported early on. A Cochrane systematic review (Fedorowicz 2013) synthesized the evidence for masseter hypertrophy, confirming consistent thickness reduction while emphasizing that response magnitude and duration vary between individuals. Adjacent evidence on masseter over-activity (Ondo 2018) reported symptom reductions in bruxism for some patients — the basis for framing any jaw-tension benefit as supportive and individual, never promised.

These references shape the masseter protocol at RE:BERRY's Gangnam aesthetic clinic: palpation of the clenched jaw by the treating physician to confirm the width is muscle before any toxin is placed; a balanced left-right dose plan drawn from the individual's own anatomy; honest counseling that onset takes 1-2 weeks, the contour builds over 4-8 weeks, the effect lasts 4-6 months, and early chewing fatigue is temporary; and any jaw-tension benefit framed as supportive, not as a promised dental treatment.
