A double chin is handled here as a single seated appointment. A thin cannula goes in through one numbed opening beneath the jaw, ultrasound energy melts the fat sitting in that pocket, and the same cannula draws it back out before you stand up. Dr. Hong Seung-hyuk, Dr. Maeng Woo-jae and Dr. Hong Yeong-ho are board-certified Family Medicine specialists working in aesthetic dermatology, and one of the three does the assessment and the procedure himself.
Most people arrive expecting either a needle course or an operation. The route used here for a submental fat pad is V-Tight, and it sits between the two. A thin cannula is placed through one numbed entry beneath the chin, ultrasound energy liquefies the fat held in that pocket, and the liquefied fat is drawn back out through the same instrument during the visit. You are awake under local anaesthesia throughout, able to answer questions while the director works. The active part runs about twenty minutes and the appointment closes inside an hour, covering the area in a single attendance. That timing is the working difference from an injectable course, which normally means at least five weekly attendances before any change reads on camera. Whether a chin belongs in this category at all is decided face to face, since slack skin behaves nothing like a fat pad.
Four stages, all of them inside one attendance. Nothing on this page is scheduled without the assessment in stage one coming back positive.
A director puts a hand under the chin and works out what is filling the space: a genuine fat pad, skin that has lost its recoil, a heavy platysma band, or simply a low-set jaw angle. Only the first of those responds to extraction. You are told which one you have, in plain words, before anything else is discussed.
Local anaesthetic is placed through one small opening in the shadow under the jaw, where the skin creases naturally. You stay awake, sitting up between checks, and you can speak throughout. Sedation exists as an option for people who want it and carries an additional fee; the agent involved is discussed only in the room, never in published material.
The cannula passes into the submental pocket and ultrasound energy breaks the fat down into a liquid state. The same cannula then aspirates it out. This is the part patients ask about most and it is also the shortest: about twenty minutes of working time for the area, with the director moving in short passes and stopping to feel the contour by hand.
A chin support is fitted before you leave and you are shown how to wear it at home. Aftercare instructions cover sleeping position, chewing, and what swelling looks like over the first week. You go straight back into your day; nobody drives you home, because nothing was given that would stop you walking out on your own.
The submental compartment is small, curved, and sits directly over structures nobody wants disturbed, so the instrument that works well across a thigh is the wrong tool for it. V-Tight was built around that constraint. Ultrasound is applied first so the fat gives way easily and the cannula does not have to tear through firm tissue to travel; the softened fat is then aspirated through the same channel. Two actions, one entry point, one sitting.
That sequence is the reason the chin route is named separately from the body work the clinic is better known for. On the trunk and limbs, mechanical extraction through a dedicated suction device does the job on its own, and the background to that family of procedures is set out on the G-fat Fat Dissolving Injection hub. Under the chin, volume is measured in small amounts and the surface reads every irregularity from across a table, so softening the fat before removing it earns its place in the protocol.
It is worth being precise about the vocabulary, because search results mix it badly. An injectable lipolysis course puts a solution into the fat so the cells shrink and the body clears them through the urinary route over weeks. V-Tight removes the fat physically during the appointment. Both are marketed in English under overlapping phrases, and the words on a brochure will not tell you which one you are being sold. Ask what leaves the room with the clinician.
International patients plan around flights, so the clock matters more here than it does for a local booking. The consultation, the marking, the numbing, the procedure itself and the fitting of the support garment are all completed within an hour of arrival. The ultrasound and extraction portion accounts for around twenty minutes of that. There is no separate surgical admission, no fasting instruction the night before, and no requirement to arrange a companion to collect you.
One attendance covers the submental area. That single-visit structure is what people usually mean when they compare this against an injectable programme, where a minimum of roughly five sessions at weekly intervals is the standard shape and the effect arrives late in the course. If you have four days in Seoul, the difference is not academic.
Booking sequence is simple. You describe the chin in a message, a director tells you plainly whether photographs suggest fat or laxity, and a same-day slot is usually possible once you are in the building for the consultation. If the assessment in the room contradicts what the photographs suggested, the appointment stops there and no procedure is performed.
The straightforward candidate has visible submental fullness with skin that still has reasonable tone: pinch the area, let go, and the skin springs back within a moment. That person gets a predictable jawline from a single attendance, because there is something to remove and a surface capable of settling back down over it once the volume is gone.
Several presentations are declined outright, and it is fairer to publish the list than to let somebody book a flight around it. Severe skin laxity is the most common refusal: emptying a pocket under slack skin can leave the area looking worse than it started, so those patients are redirected to lifting options and are told plainly that extraction is the wrong department for them. Pregnancy and breastfeeding pause the conversation entirely. An active infection anywhere on the chin, jaw or neck postpones the appointment until it has resolved. An uncontrolled systemic condition, or medication that has not been disclosed on the intake form, sends the case back to consultation before anything is booked.
Two further requests get turned down regularly. The first is the patient whose profile is set by jaw position and bone, with very little fat available to remove, where the assessment says so on the day and the plan stops there. The second is anyone treating this as weight management. Extraction under the chin addresses a defined local pocket and has no bearing on body weight, and a director who suspects that is the real goal will say the procedure is not indicated.
Volume drops during the appointment, because the fat is physically gone by the time the support garment goes on. What you see immediately afterwards is not the finished contour: the area swells, and swelling in the submental space is deceptive because it sits exactly where the fat used to be. Patients regularly report that the chin looks fuller on day two than it did before they arrived. That is expected and it passes.
The line becomes readable as the swelling settles over the following days and weeks, and the neck-to-chin angle is usually what people notice first, ahead of any change they can measure. Skin tone at the outset sets the ceiling on the result, which is the reason so much of the consultation is spent on the pinch test and comparatively little on the sheer amount of fat present. Individual results vary between two people who receive identical treatment, and no photograph of somebody else predicts what your jaw will do.
Bruising and swelling are routine and expected under the jaw, and both are more visible here than on a covered part of the body simply because the area is on show. Numbness of the chin and the skin along the jaw is common in the early period as sensory nerves recover from being handled; it typically resolves, and it is described at consultation on a scale of weeks.
Contour irregularity is the risk that most deserves attention, because the submental surface is unforgiving. Removing unevenly, or removing from a compartment whose skin cannot re-drape, can leave a dip, a ridge, or an asymmetry between the two sides that is visible in ordinary light. Nerve irritation is the second named concern: the marginal mandibular branch of the facial nerve runs close to the working field, and irritation of it can temporarily pull the smile out of balance on one side. Infection at the entry point, prolonged tenderness, and a firm area of scar tissue under the skin all belong on the same list. None of these is described here as impossible, and a consent conversation that leaves them out is not a consent conversation. Everything above is discussed in the room before consent is signed, along with what the clinic does if one of them happens after you have flown home.
You leave wearing a support garment and you are told for how long to keep it on, including overnight. Sleeping propped up for the first few nights makes a noticeable difference to morning swelling. Soft food for a day or two spares the jaw unnecessary work, and heat, alcohol and hard exercise are set aside during the early phase because all three make swelling worse in an area where swelling is already the main complaint.
Desk work is realistic the same day. Being photographed is a different question, and anyone with an event in the calendar should count in weeks. Flying is generally comfortable once the initial phase has passed; patients on short trips are asked to leave a margin between the appointment and the departure gate so that a director can see the area once before you go. If something looks wrong after you land, you write to the clinic with photographs and a director answers, and that channel stays open regardless of how long ago the visit was.
Three ways a submental pocket gets addressed, laid out so that your consultation starts from the right question. Broader background on awake fat removal across the body sits on the Liposuction in Korea page.
| Under the chin | Injectable lipolysis course | V-Tight at G Clinic | Surgical chin liposuction |
|---|---|---|---|
| What happens to the fat | Cells shrink and are cleared through the body over time | Melted by ultrasound, then aspirated during the visit | Aspirated in an operating setting |
| Openings in the skin | Repeated needle punctures across the pad | One entry point in the jaw shadow | Small incisions, often more than one |
| Anaesthesia | Topical or none | Local, awake and talking | Sedation or general anaesthesia |
| Attendances | Around five weekly sessions as a minimum | A single visit for the area | One operation with a formal admission |
| When the change reads | Late in the course, gradually | Volume on the day, contour as swelling drains | On the day, behind a longer swollen phase |
| Back to desk work | Immediately | Same day, under a support garment | Days, with a recovery plan |
| Typically chosen for | A small soft pocket, no time pressure | Defined submental fullness with sound skin tone | Cases handled alongside other jaw surgery |
This table is general information about three categories of care. Which one suits your chin depends on your anatomy, your skin, and your medical history, and a resident director works through it with you at the free consultation.
Three references are listed below so a reader can go to the sources directly. The first examines tumescent liposuction and the efficacy of a lower lidocaine dose at 400 mg per litre (Böni, 2010). The second reports on the safety of liposuction using exclusively tumescent local anesthesia across 3,240 consecutive cases (Habbema, 2009). The third describes liposuction of the neck and jowls by a five-incision method combining machine-assisted and syringe aspiration (Langdon, 2000). Those sentences state what each paper is titled and nothing beyond it.
None of these papers studied G Clinic, none describes the V-Tight protocol used at this address, and none of them supports a prediction about what your own jawline would do. Published literature of this kind establishes that a method category has been examined in the peer-reviewed record. It does not transfer to an individual consultation room, and it is cited here as background only.
There is no international rate published for the submental procedure on this page, and the blank is deliberate. Printing a figure the clinic has not confirmed for international patients would be worse than printing nothing, so the fee is confirmed to you directly at the free consultation, once a director has seen the area and agreed what is actually being treated. Consultation required.
What you can expect is that the quote is given before consent, in writing, with the sedation option priced separately if you want it. Nothing is charged for the assessment itself, and a consultation that ends in a referral elsewhere costs you nothing either.
The name suggests a dissolving shot, but G-fat injection physically removes fat. G Clinic developed it in Gangnam, Seoul, reporting 20,000+ cases since 2018. Local anaesthesia keeps you awake; one micro-entry per area lets a fine cannula with device suction take fat out the same day, priced by palm-sized area. Family members include third-generation G-Lifting, whose special cannula stimulates skin tightening before extraction, and Ultra G-fat, ultrasound plus extraction. Read the full story on the G-fat Injection page.
They are separate categories. An injectable course places a solution that shrinks the fat cells so your body clears them gradually, and it normally runs to around five weekly attendances before the effect reads. V-Tight melts the pocket with ultrasound and draws it out through a cannula in one sitting. Background on both approaches sits on the G-fat Fat Dissolving Injection hub.
Plan for about an hour from arrival to leaving, assuming the consultation on the day confirms you are suitable. The ultrasound and extraction portion itself takes roughly twenty minutes; the rest is assessment, marking, numbing, and fitting the support garment before you go. There is no admission, no fasting, and no need to arrange somebody to collect you afterwards.
No. The area is numbed with local anaesthesia and you stay awake, sitting up between checks and able to talk with the director the whole time. Sedation is available as an option for patients who prefer it and carries an additional cost. The specific agent is discussed with you in the consultation room and is never named in published material, which is a rule of Korean medical advertising.
The fat cells removed during the appointment are gone from that pocket. What the procedure cannot do is freeze your body in place: significant weight gain afterwards will still be stored somewhere, including in remaining cells around the treated area, and a jawline can lose definition again for that reason. A director explains this before consent is signed.
Probably not with extraction. Where the fullness comes from skin that has lost its recoil, emptying the pocket underneath can leave the area looking looser than it did at the start. Those patients are redirected to lifting options and told directly that this page is the wrong department for them. The pinch test at consultation is what settles the question.
Bruising and swelling first, both of them routine and both visible because the area is uncovered. Then numbness of the chin and jawline skin while sensory nerves recover, contour irregularity or asymmetry between the two sides, irritation of the marginal mandibular nerve which can temporarily unbalance a smile, infection at the entry point, prolonged tenderness, and firm scar tissue under the skin.
Surgical chin work is generally done under sedation or general anaesthesia, often through more than one incision, with a formal admission and a longer recovery plan. V-Tight uses one entry point in the jaw shadow, local anaesthesia, and a same-day discharge on foot. Awake fat removal across the body more broadly is covered on the Liposuction in Korea page.
Flying is usually comfortable once the earliest phase has passed, but we ask short-stay patients to leave a margin between the appointment and the departure gate so a director can look at the area once more before you travel. If you land and something concerns you, send photographs; a director answers directly and that channel does not close after a set period.
Access is through a single small opening placed in the natural shadow beneath the jaw, where it sits out of the sightline in ordinary conversation. It is not an incision requiring formal closure. Any entry point in skin leaves some mark while it settles, and how a given person heals varies, so this is reviewed with you at consultation against your own skin.
Volume drops on the day, since the fat leaves during the appointment. The visible line takes longer, because swelling settles into the same space the fat occupied and the chin can look fuller on day two than it did beforehand. The neck-to-chin angle is generally what patients notice first as that resolves over the following days and weeks.
Dr. Hong Seung-hyuk, Dr. Maeng Woo-jae and Dr. Hong Yeong-ho are the three resident medical directors, all board-certified Family Medicine specialists working in aesthetic dermatology, and one of them does your assessment and your procedure personally. You may request a particular director when you enquire and we will match it to the schedule where availability allows.
Because an international rate for the submental procedure has not been published, and posting a figure the clinic has not confirmed for overseas patients would be misleading. The fee is confirmed to you at the free consultation once a director has examined the area, in writing, before consent, with the optional sedation charge itemised separately if you choose it.
Frequently, yes, and many international patients plan it that way because both are awake procedures with same-day discharge. Whether they happen on the same day or on separate days depends on how much total area is involved and on what the director judges reasonable for one sitting. That sequencing is planned at consultation and never assumed in advance.
That single answer decides everything else on this page, and it costs nothing to ask. Send a profile photograph of your chin and one of the three resident directors will tell you which category you are in before you book a flight to Gangnam, Seoul.

Yesterday, I had a fat extraction procedure from Dr. Hong Young-ho. The staff, especially the doctor, were so kind that it was very comfortable. Right after the procedure, it was just a little uncomfortable yesterday because of swelling, but today there is almost no pain and I'm waiting for the swelling to go away to see the beautiful res…
Recommendations are made based on actual circumstances. The attitude is very good. Highly recommended.
I cannot recommend G-clinic highly enough. From the moment I walked in, my experience was nothing short of exceptional. The clinic itself is modern, clean, and welcoming. The front desk staff were incredibly warm and efficient. Checking in was a breeze, and they were very helpful with my new patient paperwork. The waiting time was minimal…
Process was perfect! I got some liposuction done, the doctor and staff were very nice and very professional. 100% would recommend anyone to get there procedures done here! They took out A LOT of fat! The doctor speaks perfect English as well!
