A localized fat-dissolving injection targets the submental fat under your jaw, usually over 2 to 4 sessions spaced about 4 weeks apart for a smoother contour.
Double chin treatment near Incheon Airport typically uses a localized fat-dissolving (lipolytic) injection that targets submental fat under the jaw, gradually clearing treated fat cells over 2 to 4 sessions spaced about 4 weeks apart. It is a non-surgical body-contour approach, not a weight-loss method, and is planned individually at consultation.

A double chin is submental fat that collects under the jaw and softens the jawline, and it often persists even at a healthy weight because it is partly genetic. A fat-dissolving injection is a non-surgical way to address this specific fat pocket. A lipolytic solution is placed directly into the submental fat, where it breaks down fat cells that are then gradually cleared by the body over the following weeks.
Because the effect is gradual, this is a course treatment rather than a single fix. Most people have about 2 to 4 sessions spaced roughly 4 weeks apart, letting the area settle between visits while the contour refines. It targets a localized fat pocket under the chin, so it is a body-contour treatment, not a weight-loss programme or appetite medication.
At our Incheon Airport (Yeongjongdo) location, Dr. Sunbeen Kim, Medical Director, assesses your submental fat and skin, then explains whether injection alone or a combined approach best suits your jawline goal, in English. Because we are near ICN, many international patients begin treatment around a flight or stopover and continue on return visits.
The treatment works by delivering a lipolytic (fat-dissolving) solution through fine injections directly into the submental fat pocket under the chin. The solution disrupts the membranes of fat cells in that localized area, and over the next several weeks the body gradually clears the broken-down fat, so the under-chin contour becomes smoother. Because the response is progressive, the plan is usually spread across about 2 to 4 sessions spaced roughly 4 weeks apart, which also lets expected swelling settle between visits. The doctor maps the injection points to your specific fat pattern, keeping treatment confined to the target zone. This differs from energy devices for the same area: HIFU (high-intensity focused ultrasound) uses focused ultrasound and cryolipolysis uses controlled cooling, whereas the injection acts chemically on the fat cells. Crucially, this is a treatment for 1 localized area of fat, not a way to lose overall body weight, so a stable weight helps the result hold. The number of sessions and injection points is tailored after assessment rather than fixed in advance.

The doctor examines how much submental fat sits under your jaw and checks skin quality, which shapes a plan of about 2 to 4 sessions.
Fine injection points are marked across the 1 submental target zone so the lipolytic solution reaches the fat evenly.
The solution is injected into the fat in a session that usually takes about 15 to 30 minutes, disrupting fat cell membranes.
Over the following 4 or more weeks the body gradually clears the broken-down fat, so the contour refines between sessions.
Most contours need 2 to 4 sessions spaced about 4 weeks apart, with the doctor reviewing progress before each visit.

Dr. Sunbeen Kim, Medical Director, assesses your submental fat and skin, then explains the method and expected 2 to 4 session course, in English.
A session usually takes about 15 to 30 minutes, with numbing used before the lipolytic solution is injected into the target zone.
Plans run as a course of about 2 to 4 sessions spaced roughly 4 weeks apart, letting the area settle between visits.
The contour refines gradually over the weeks after each session as treated fat clears, with progress reviewed before the next visit.
Once localized fat is reduced it does not return in the same way, so a stable weight and simple aftercare help maintain the jawline.
It is a non-surgical treatment where a lipolytic solution is injected into the submental fat under your jaw, gradually clearing treated fat cells over weeks. It targets a localized fat pocket, not overall body weight. You can see how it works on our slimcut injection page.
The lipolytic solution disrupts fat cell membranes in the submental area, and over the following weeks your body gradually clears the broken-down fat, smoothing the under-chin contour. Because it works progressively, most people need about 2 to 4 sessions. Your doctor maps the injection points to your specific fat pattern at consultation.
No, a fat-dissolving injection is a body-contour treatment for a localized submental fat pocket, not a weight-loss programme or appetite medication. It reduces fat in one target area rather than lowering overall body weight. Keeping a stable weight helps the result last, which your doctor explains during planning.
Most people need about 2 to 4 sessions spaced roughly 4 weeks apart, as the fat clears gradually between visits rather than after one appointment. The exact number depends on your submental fat volume and how it responds. Your doctor reviews progress before each session and adjusts the plan accordingly.
Most people feel a brief sting and some pressure during the injections, and numbing options keep the session comfortable. Afterward, temporary swelling and tenderness under the chin are normal and settle over several days. Your doctor explains what to expect and how to manage it before you begin the plan.
Downtime is usually short. Temporary swelling, tenderness, and sometimes mild bruising under the chin are common and ease over several days to about a week. Most people return to daily activities quickly. Sessions are spaced about 4 weeks apart partly so the area fully settles before the next treatment.
The contour refines gradually over the weeks after each session as treated fat clears, rather than immediately. Many people notice change building across the 2 to 4 session course. Your doctor reviews before-and-after progress between visits so the plan stays matched to how your submental area is responding.
Once localized submental fat cells are reduced, they do not return in the same way, so results can be long-lasting at a stable weight. Significant weight gain can enlarge remaining fat cells, so weight stability matters. Your doctor discusses maintenance and realistic expectations as part of the plan.

Yes, if there is early skin laxity along with fat, your doctor may add a tightening step so the jawline looks smoother after fat is reduced. Combining is planned carefully to avoid over-treating the area. You can review energy-based tightening on our RF body skin tightening page.
A fat-dissolving injection acts chemically on fat cells over a short course, while HIFU uses focused ultrasound and cryolipolysis uses controlled cooling. Injection suits defined fat pockets, while HIFU can add tightening. Your doctor recommends the best fit for your anatomy after assessing your submental fat and skin at consultation.
Most adults with a localized submental fat pocket at a stable weight are suitable candidates. A consultation checks whether fat reduction alone fits your goal or whether tightening should be added. Significant skin laxity or certain medical conditions are reviewed first, which your doctor explains clearly before starting any plan.
Fat-dissolving injection is widely performed and generally considered safe when a trained doctor assesses your anatomy and injects carefully into the correct plane. Temporary swelling, bruising, and tenderness are the usual effects. A consultation screens for contraindications first. You can read more on our injection treatment page.
The common effects are temporary and local: swelling, tenderness, bruising, redness, and sometimes numbness under the chin that settles over days to weeks. Serious effects are uncommon when injections are placed correctly. You can read more about the approach on our injection treatment page.
Aftercare is simple: follow your doctor’s advice to manage swelling, avoid heavy pressure or vigorous massage on the area early, and protect the skin. Most guidance is included in your plan. A gentle skin care routine supports recovery between sessions while the contour continues to refine.
For a first session, 1 to 2 days is usually comfortable, covering a consultation, the injection, and a short review. Because the plan runs across 2 to 4 sessions, many international patients start here near ICN and continue on return trips. Our English-speaking team helps schedule around your flights and stopovers.
Yes, flying within a day or so is generally fine, as the injection is minimally invasive, though visible swelling may still be present during travel. Staying hydrated and following aftercare helps. Being near ICN in Yeongjongdo means our team can time your session around a departure or stopover with English support.
If you arrive through ICN, our Incheon Airport (Yeongjongdo) location is the most convenient, with Dr. Sunbeen Kim, Medical Director, and full English support. We also have Seoul locations in Gangnam and Myeongdong. Your treatment notes are kept on file so follow-up sessions can continue at whichever location fits your travel.
