A localized fat-dissolving injection reduces a submental fat pocket over a series of 2 to 4 sessions, spaced about 4 weeks apart, with results building over roughly 4 to 6 weeks each time.
Double chin treatment in Myeongdong, Seoul most often uses a localized fat-dissolving (lipolytic) injection, where a compound like deoxycholic acid is injected into submental fat so the body clears it over weeks. Most defined double chins need 2 to 4 sessions about 4 weeks apart. It is a contouring treatment for fat, not a weight-loss method or diet drug.

A double chin is a build-up of fat, and sometimes loose skin, beneath the jaw. The most common non-surgical treatment for the fat component is a localized fat-dissolving (lipolytic) injection: small amounts of a compound such as deoxycholic acid or a phosphatidylcholine blend are placed into the submental fat through a grid of fine injections. The compound disrupts fat-cell membranes, and the body gradually clears the treated fat over several weeks.
This is a contouring treatment for a defined fat pocket, not a way to lose overall body weight and not an appetite or diet medication. Because results build gradually and each session only clears the fat it treats, most defined double chins improve over a series of 2 to 4 sessions spaced about 4 weeks apart. Swelling under the chin is common in the first several days after each session and settles as the area heals.
At our Myeongdong (Seoul) location, double chin treatment is consultation-led by Dr. Seung Jae Baek, Medical Director. The first step is confirming your concern is fat rather than skin laxity or muscle banding, because that determines whether injections are the right choice. International patients are supported in English across Myeongdong, Seoul, Korea, with follow-up sessions easy to schedule around a trip.
A fat-dissolving injection works by delivering a lipolytic compound directly into the subcutaneous fat under the chin, usually as a grid of small injections spaced across the area. Deoxycholic acid, a molecule the body also uses to break down dietary fat, disrupts the membranes of fat cells so they release their contents; phosphatidylcholine formulations act on the same fat. Over the next several days an inflammatory clearance response removes the damaged cells, and the contour refines gradually over about 4 to 6 weeks per session. Because each session addresses only the treated fat, most defined double chins need a series of 2 to 4 visits about 4 weeks apart, with swelling most noticeable in the first 3 to 5 days. The doctor chooses the number of injection points and the fat volume treated based on your anatomy, which is assessed in person. Once a treated fat cell is cleared it does not return, though remaining cells can still enlarge with weight gain, so staying weight-stable protects the result.

The doctor confirms your double chin is mostly fat, since 1 case driven by loose skin will not respond well to fat-dissolving injections.
A grid of small injections is planned across the submental fat, with the number of points based on the fat volume treated.
After numbing, the session takes roughly 15 to 30 minutes, placing the lipolytic compound into the fat under the chin.
Over about 4 to 6 weeks the body clears the treated fat cells, with swelling most noticeable in the first 3 to 5 days.
Because each session clears only the fat it treats, most defined double chins need 2 to 4 sessions about 4 weeks apart.

Dr. Seung Jae Baek assesses whether your double chin is fat, skin, or muscle, and confirms whether fat-dissolving injections suit you, in English.
If suitable, a session takes roughly 15 to 30 minutes, placing a grid of small injections into the submental fat after numbing.
Plans run as a series of 2 to 4 sessions about 4 weeks apart, so the full course is mapped across several visits, not one appointment.
Each session builds gradually over about 4 to 6 weeks, with swelling most noticeable in the first 3 to 5 days after injection.
Treated fat cells do not return, but staying weight-stable protects the contour; the clinic reviews progress between sessions.
It is most often a localized fat-dissolving injection, where a compound such as deoxycholic acid is placed into submental fat so the body clears it gradually over weeks. Most defined double chins need 2 to 4 sessions. See the full overview on our fat-dissolving injection page to learn more.
No, it is a contouring treatment for a defined pocket of fat, not a way to lose overall body weight. It does not affect appetite and uses no diet or slimming medication. If general weight loss is your goal, this is the wrong tool, which the clinic explains honestly during your Myeongdong consultation.
You feel a stinging or burning sensation during the injections and swelling afterwards, but numbing cream and careful technique keep it manageable for most people. Tenderness usually peaks in the first 3 to 5 days. Your doctor explains comfort measures at consultation before any treatment at our Myeongdong location.
Most people have swelling, tenderness, and sometimes bruising under the chin for several days, with swelling often most visible in the first 3 to 5 days. Some recovery is normal, so there is no claim of instant, effortless results. Your doctor describes the typical timeline honestly before you start.
Most defined double chins need a series of 2 to 4 sessions spaced about 4 weeks apart, because each session clears only the fat it treats. The exact number depends on the fat volume and how you respond, which the doctor reviews between visits and adjusts as your contour refines.
Results build gradually over about 4 to 6 weeks after each session as the body clears the treated fat, not immediately. Early swelling can temporarily mask the change. Because improvement accumulates across the series, your doctor reviews progress between sessions before planning the next visit.
Injections suit a defined fat pocket, HIFU adds skin tightening for mild laxity, and cryolipolysis suits larger pinchable bulges. The right choice depends on whether your concern is mostly fat or fat plus loose skin. Our team can review ultrasound lifting at consultation.
You are likely suitable if your double chin is a defined pocket of subcutaneous fat and you are in good general health. A consultation confirms candidacy. If skin laxity is the main issue, the doctor may suggest a thread lift or ultrasound lifting instead of injections.
Common effects include swelling, tenderness, bruising, redness, and temporary numbness under the chin, which usually settle within days to weeks. Less common issues are reviewed at consultation. This treatment is not free of all effects, so a good clinic checks your history and explains what to watch for after each session.
Yes, when there is both fat and mild skin laxity, injections can be paired with a skin-tightening method for a sharper jawline. Sequencing matters, so the doctor plans the order. You can explore options such as RF skin tightening during your Myeongdong consultation.
Once treated fat cells are cleared they do not return, so results can be long-lasting, but remaining fat cells can still enlarge with weight gain. Staying weight-stable protects your contour. The clinic frames the outcome as durable rather than a fixed forever guarantee that ignores lifestyle changes.
Expect mild swelling and tenderness, so avoid heavy pressure on the area, stay hydrated, and protect any bruising from the sun for a few days. Your doctor gives tailored aftercare on our fat-dissolving injection page and checks your response before scheduling the next session in the series.
Cost depends on the method, the fat volume, and the number of sessions, usually 2 to 4 for injections, so it is set at consultation rather than one fixed online figure. This keeps pricing honest to your anatomy. You can review the treatment first on our fat-dissolving injection page.
Our Myeongdong (Seoul) location is at 5, Myeongdong 10-gil, Jung-gu, Seoul, about 5 minutes from Myeongdong Station, so follow-up sessions are easy during a trip. Dr. Seung Jae Baek, Medical Director, leads consultations in English for international patients seeking double chin treatment.
A single session needs only a short visit, so 1 to 2 days is enough, covering a consultation and the procedure with time for early swelling to begin settling. Because a full course runs across weeks, many international patients start in Seoul and continue on return trips coordinated by our English-speaking team.
Yes, flying within a day or so is generally fine, as the treatment is minimally invasive, though swelling under the chin may still be visible during travel. Stay hydrated and avoid pressure on the treated area. Your doctor gives specific aftercare advice so you can travel comfortably after your Myeongdong session.
