Minutes from ICN Airport
Incheon AirportWhat is mandibular line botox, and how does it change the jaw corner?
Mandibular line botox aims at the shape of the jaw at its angle: the corner near the earlobe where the lower face turns up toward the ear. The muscle covering that corner is often the reason the angle looks sharp and wide, and relaxing it lets the corner soften and the whole lower-face line read rounder over four to eight weeks. It is the same botulinum toxin used elsewhere in the face, placed with the jaw-angle contour as the goal. At RE:BERRY Gangnam one licensed physician maps each side, injects, and reviews, and Spanish-speaking guests are guided on WhatsApp from before the trip through the settling weeks.
Effects & Progress
Effects & Progress
Mandibular line botox is aimed at the jaw corner, so the amount at each angle is weighted to how far that side flares rather than dosed as one fixed figure across the whole muscle.
The injections are done in minutes with no wound, so daily life resumes at once. The jaw corner looks unchanged for now; muscle needs weeks, not hours, to respond.
The muscle at each corner starts to relax. Some guests feel the jaw a little tired on firm food, which passes on its own before the angle begins to change shape.
The main window: the corner eases from sharp toward rounded and the lower-face line reads softer as the muscle settles from lighter use. Response speed varies by individual.
Maintenance period. The softened corner holds four to six months before the muscle regains activity; RE:BERRY will guide the repeat interval that keeps the jaw-angle line.

Effects & Progress
A square jaw usually reads square from its corner, the angle near the ear, more than from the front, so mandibular line botox is planned around that corner rather than the whole muscle. The amount placed at each angle is weighted to how far that particular side flares, which matters because most jaws are uneven: one corner juts more than the other from years of use. Dosing each corner to its own flare is how the two angles ease toward each other instead of both dropping by the same fixed number and leaving the jaw as lopsided as it started.
Because the effect works through a muscle relaxing and then being used less, the jaw corner softens gradually across roughly four to eight weeks rather than the day of the session, easing from a hard corner into a rounder curve. The visit itself is the opposite of slow: the injections take minutes, there is no wound to bandage, and a same-day flight home is fine. That pairing, a short appointment and a change that unfolds over weeks, is what lets the treatment sit inside a Seoul itinerary without adding recovery days to a trip.
Most jaws flare more on one corner than the other, and treating both with an identical amount would keep that imbalance in place. Mapping each corner separately lets the physician address the asymmetry directly, weighting the side that juts more so the two angles finish closer together than they began. This is why the read starts with tracing the jaw line and clenching on each side: the aim is not simply a smaller jaw but a lower-face line that curves the same on the left as on the right, which a per-side plan is built to deliver.
A course is not a one-time change: the relaxed corner holds for a stretch of months, then the muscle gradually regains activity and the angle drifts back toward its starting shape. A repeat at the right interval keeps the jaw-angle line where the first plan set it, and many guests find later sessions need a little less as the corner stays relatively eased between visits. The physician sets that interval from how an individual muscle recovers rather than a fixed calendar, and for Spanish-speaking guests the timing is confirmed on WhatsApp so a return trip can be planned around it.

Mandibular Line Botox — 4 Steps from Jaw-Angle Read to Follow-Up
※ Illustrative images are AI-generated to help explain the treatment process.
What Mandibular Line Botox Delivers, and How the Corner Softens Over Time
- A rounder jaw corner: the angle near the ear eases from a sharp corner into a smoother curve, so the lower-face line reads softer without anything added or removed
- Read from your own two angles: because the left and right corners seldom flare the same, the dose is weighted per side so the finished jaw line stays even rather than lopsided
- A short, wound-free visit: the injections take minutes and leave nothing to bandage, so the appointment fits inside a Seoul itinerary and a same-day flight is fine
- Spanish end to end: coordinators handle the pre-trip questions, the in-room read, and the follow-up in Spanish, so a language gap never sits between you and the jaw shape you asked for
- One physician the whole way: the doctor who reads your jaw angle marks the map, places every point, and checks your review, with no handoff between planning and doing
- Repeatable by design: the softened corner holds for a stretch of months, and a repeat at the right interval keeps the line where you want it, often needing less each time
| Timeline | What to Expect |
|---|---|
| The injections are done in minutes and daily life resumes at once. The jaw corner looks the same as before; muscle needs weeks to respond, so there is nothing to see yet | |
| The muscle at each corner starts to relax. Some guests feel the jaw a little tired when chewing something firm, which passes on its own before the shape begins to change | |
| The main window: the corner eases from sharp toward rounded and the lower-face line reads softer as the muscle settles from lighter use. Response speed varies by individual | |
| The softened corner holds through this stretch, then the muscle gradually regains activity. A repeat session keeps the jaw-angle line where the first plan set it |
Softening a Jaw Corner: Mandibular Botox vs Chin Filler vs a Lifting Device
| Criteria | Mandibular Line Botox (RE:BERRY Gangnam) | Chin / Jawline Filler | Energy Lifting (HIFU / RF) |
|---|---|---|---|
| What it addresses | A sharp, wide muscle bulge at the jaw angle | A short chin or a gap in the jaw outline | Skin that has slackened along the lower face |
| Why the jaw reads square | Muscle flaring at the corner near the ear | A profile that stops short at the chin | Not the cause it addresses |
| How the change arrives | Gradually, over 4-8 weeks as muscle relaxes | At once, by adding structure | Builds over weeks as collagen forms |
| Read per side | Dose weighted to each corner's flare | Volume shaped to the profile | Passes set to the laxity pattern |
| Sessions | One, repeated every 4-6 months at first | One, topped up as it resorbs | Usually one per cycle |
| Downtime | None | Possible brief swelling or bruising | None to a day of redness |
| Best when the corner is | Firm muscle that stands out on a clench | Set back or unbalanced in profile | Draped in loose, sagging skin |
Why This Matters
A square jaw corner has more than one possible cause, and the fix depends on which one is yours. Mandibular line botox helps when the corner is muscle: the firm bulge that hardens when you clench near the ear. If the outline reads harsh because the chin sits back in profile, filler shapes that outline instead; if the corner is soft and the skin has dropped, a lifting device is the tool. The physician at RE:BERRY Gangnam reads the corner first so the plan matches the real reason your angle looks sharp.
This page is about the jaw angle specifically, the corner where the lower face turns up toward the ear, and mandibular line botox is planned around that corner more than the whole jaw. Where a broad jaw is treated for overall width and the clenching behind grinding, a mandibular plan concentrates on the flare of the angle itself and how the two corners sit relative to each other. That focus is why the read starts with tracing your jaw line before anything is marked.
KHIDI's 2025 international patient survey found 41.4% of respondents rank keeping the same doctor throughout as their leading criterion. At RE:BERRY Gangnam the physician who reads your jaw angle draws the per-side map, injects every corner point, and reads your review: the person who plans the shape is the person who carries it out, and for Spanish-speaking guests a coordinator keeps that thread unbroken on WhatsApp.

The Evidence Behind Contouring the Jaw Angle
Botulinum toxin type A acts at the neuromuscular junction, blocking the release of acetylcholine so a muscle receives less of the signal that tells it to contract. Applied to the muscle at the jaw angle, this means the corner contracts with less force and is used less over the following weeks. A muscle used less undergoes disuse reduction. So the sharp corner softens gradually over the following weeks, not on the day of the injection, and the change is anatomical: the bulk at the angle eases, with nothing added to the face.
The specific outcome at the jaw angle is documented. A clinical study of botulinum toxin type A for aesthetic mandibular contouring recorded measurable narrowing of the lower face after injection into the jaw muscle, establishing muscle reduction as the mechanism that softens a square angle. Earlier work on hypertrophy of that muscle traced the same effect, showing that relaxing an overdeveloped jaw muscle reduces its bulk and eases the corner it creates.

How much toxin is placed, and where, governs both the result and how long it holds, so the per-corner dose is chosen from your own two angles and not a fixed figure. Randomized controlled work on facial botulinum toxin has mapped the relationship between dose, effect, and duration, and equivalence trials have confirmed a consistent response profile across repeated facial treatment. That evidence base supports weighting the amount at each jaw corner to its flare and setting the repeat interval to how an individual muscle recovers.

Questions International Guests Ask About Mandibular Line Botox in Gangnam
What exactly does mandibular line botox change?
It changes the shape of the jaw at its angle, the corner near the earlobe where the lower face turns up toward the ear. The muscle covering that corner is often what makes the angle look sharp and the jaw read square. Relaxing it lets the corner ease from a hard corner into a rounder curve, so the whole lower-face line looks softer. The physician at RE:BERRY Gangnam plans around that corner specifically, not the entire jaw, and weights each side to how much it flares.
How is this different from botox for a wide jaw or teeth grinding?
The muscle is the same one, but the plan is aimed differently. A broad-jaw approach treats overall width and the clenching that drives grinding, whereas a mandibular line plan concentrates on the flare of the angle itself and on evening the two corners. If grinding and jaw tension are your main concern, the physician will say so and shift the focus; if the goal is the jaw-angle shape, the map stays on the corners. The read at the start sorts out which one fits you.
Do you offer the consultation in Spanish?
Yes, from the first message to the last follow-up. Spanish-speaking coordinators answer pre-trip questions on WhatsApp, sit in on the in-room read so the physician's explanation of your jaw angle reaches you in Spanish, and keep the review going in Spanish after you fly home. RE:BERRY is reservation-only for international guests, so confirming your slot and language support before you travel is part of the booking.
How soon will the jaw corner look softer?
It follows a muscle's pace. The muscle begins relaxing in roughly one to two weeks, and the corner visibly rounds over about four to eight weeks as it settles from lighter use. If you are timing this to an event, plan for the change to develop across the two months after the session, not within the same week. Guests who send a photo at six weeks usually see the clearest difference against the treatment day.
Will both sides of my jaw be treated the same?
Rarely, because most jaws flare more on one side than the other. The physician writes a separate amount for each corner and doses the side that juts more a bit more heavily, so the two angles ease toward each other. A jaw treated with an identical dose on both sides can end up looking as uneven as it started, which is the reason the map is drawn per corner from your own two sides.
How long does mandibular line botox last?
The relaxing effect on the corner muscle usually holds four to six months. After that the muscle gradually regains activity and the angle drifts back toward its starting shape, so a repeat maintains the softer line. Many guests come back two to three times in the first year, then less often as the muscle stays relatively eased. The physician sets your interval from how your own corner responds, not a fixed calendar.
Can I still chew and speak normally afterward?
Yes. The dose targets the outer part of the corner muscle and is set to soften the angle, not to switch the muscle off, so normal eating and speaking continue. Some guests notice the jaw a little tired on very firm food in the first week or two while it adjusts, and that passes on its own. The physician suggests going easy on hard chewing for the first couple of days as a precaution, nothing more.
Will it hurt, and how are the injections placed?
Most guests describe brief pinches rather than real pain. A fine needle places the toxin at a few marked points over each jaw corner, and the whole set is finished in minutes with nothing to bandage. The physician checks that the placement matches the per-side map before you sit up, since balanced delivery is what keeps the finished jaw line even on both corners.
Is there any downtime, and can I fly home the same day?
There is no downtime that affects a trip. The injections leave no wound, so makeup, meals, sightseeing, and a same-day flight are all fine. For the first day or two the physician suggests skipping jaw massage, not lying face-down right after, and going gently on very hard food. Those are light precautions; the only thing that unfolds slowly is the softening of the corner itself over the following weeks.
Who is a good candidate for mandibular line botox?
Good candidates have a jaw corner that is muscle: a firm bulge that stands out when they clench near the ear, making the angle look sharp. It is not scheduled during pregnancy or breastfeeding, or with certain neuromuscular conditions. If the corner stays soft on a clench, the shape is coming from fat or the skeleton, and the physician at RE:BERRY Gangnam will tell you directly and map a filler or lifting plan instead.
Will it change the rest of my face or my smile?
It should not. The injection stays on the lower and outer part of the corner muscle and keeps clear of the muscles that shape a smile and expression. Because it acts only there, the effect stays at the jaw angle, and the rest of the face is unaffected. What changes is the corner easing from sharp to rounded; your expressions and the way your face moves stay your own.
Do I need a visa, and how do the logistics work for a visit from a Spanish-speaking country?
Entry rules depend on your nationality, so a coordinator will point you to the current requirement for your passport before you book; many Spanish-speaking travelers use a short-stay entry, but check your own case. On the ground, the read, the mapping, and the injection fit into a single visit, and the follow-up continues on WhatsApp in Spanish once you are home, so the treatment itself does not stretch your trip.
How do I book mandibular line botox as a foreign visitor?
Message RE:BERRY on WhatsApp with your goal for the jaw angle and your travel dates, in Spanish or English. A coordinator replies within a few hours to reserve a physician slot and confirm language support; the clinic is reservation-only for international guests and staff interpreters cover eight languages. The consultation and the injection happen in one visit, and the review carries on over WhatsApp after you fly back.
Where is the clinic, and how do I get there from Gangnam Station?
RE:BERRY is inside KI Tower on Gangnam-daero, a two-minute walk from Gangnam Station Exit 10 on Seoul Metro Line 2. From Incheon Airport it is roughly 45 to 60 minutes by AREX plus subway or by direct taxi. Being steps from the station means a mandibular botox appointment slots cleanly between the rest of a Gangnam itinerary, whether you are in Seoul for a few days or a longer stay.

Science Mandibular line botox: peer-reviewed references
Contouring the jaw angle with botulinum toxin rests on a documented mechanism and outcome record. Kim (2005) reported measurable narrowing of the lower face after botulinum toxin type A injection for aesthetic mandibular contouring, establishing muscle reduction as the basis for softening a square angle. To (2001) traced the same effect in hypertrophy of the jaw muscle, confirming with ultrasound and electromyography that relaxing an overdeveloped muscle reduces its bulk. Randomized controlled and equivalence work on facial botulinum toxin (Carruthers 2002; Kane 2015) mapped how dose relates to effect and duration and confirmed a consistent response across repeated treatment, which informs weighting the amount at each jaw corner to its flare and setting the repeat interval to the individual.
