Non-surgical contouring uses fat-dissolving injection to target a localized under-chin fat pocket, typically over a staged course of 2 to 4 sessions.
Double chin treatment near Hongdae most often uses fat-dissolving injection, a localized deoxycholic-acid-type lipolytic treatment that breaks down a small under-chin fat pocket over a staged course of 2 to 4 sessions. It is non-surgical contouring, not weight loss. For patients near Hongdae Station, care is provided across our Reberry Clinic Seoul locations with English support.

Double chin treatment refers to non-surgical methods that reduce or contour fullness under the chin, most commonly with fat-dissolving injection. This is a localized, deoxycholic-acid-type lipolytic treatment: medication is injected directly into a small pocket of submental (under-chin) fat, where it disrupts fat-cell membranes so the body gradually clears them. The result is a more defined jawline and chin over several weeks, without surgery.
It is important to understand what the treatment targets. Fat-dissolving injection addresses a specific fat pocket, so it works best when the fullness is genuinely fat rather than skin laxity or jaw structure. Because the fat is cleared gradually, most people need a staged course of 2 to 4 sessions spaced about 4 to 6 weeks apart, with some swelling expected in the first days after each session. This is localized contouring, not a systemic weight-loss method, so it refines the chin area rather than reducing overall body weight.
At Reberry Clinic, double chin care is consultation-led: the clinic’s doctors first confirm whether the fullness is fat, laxity, or structure, then build a tailored plan and explain it clearly in English. For international patients searching near Hongdae (Hongik Univ.) Station, care is provided across our Seoul locations (Gangnam, Myeongdong), easily reached from 홍대입구역.
Fat-dissolving injection treats a double chin by delivering a lipolytic, deoxycholic-acid-type agent into localized subcutaneous fat under the chin. Once injected, the agent disrupts the membranes of fat cells in that pocket, and over the following weeks the body’s natural clearance processes remove the destroyed cells, gradually reducing the fullness. Because the effect is targeted to where the medication is placed, a doctor maps injection points across the fat pad and adjusts the number of units to the size of the pocket, rather than using a fixed dose for everyone. Submental fat typically responds over a course of 2 to 4 sessions spaced about 4 to 6 weeks apart, since each session removes a portion of fat and the area needs time to settle between visits. The treatment is specific about what it does: it contours a defined fat pocket and is not a systemic weight-loss method, so it will not slim the whole face or body. Where a doctor finds that skin laxity contributes to the fullness, they may recommend combining injections with a skin-tightening approach, so the treated area looks firm rather than soft after the fat is reduced.

A doctor spends the first 10 to 15 minutes confirming whether the fullness is fat, skin laxity, or jaw structure, since injections only address fat.
The under-chin fat pad is marked and a conservative number of injection points is planned, matched to the size of your specific fat pocket.
The lipolytic agent is injected in a session of about 15 to 30 minutes, disrupting fat-cell membranes in the treated pocket.
Over the next 4 to 6 weeks, the body gradually clears the destroyed fat cells, so the contouring builds after each session rather than instantly.
Most people complete 2 to 4 sessions about 4 to 6 weeks apart, with the doctor reviewing progress and adjusting the plan between visits.

The clinic’s doctors examine your chin, confirm whether the fullness is fat or laxity, and explain the plan and cost factors in English before treatment.
A fat-dissolving session usually takes about 15 to 30 minutes, with numbing applied to the small under-chin area before the injections.
Treatment runs as a course of 2 to 4 sessions about 4 to 6 weeks apart, rather than a single visit, so the fat is reduced gradually.
Swelling settles over the first week, and each session’s fat reduction becomes visible over the following 4 to 6 weeks.
Once a fat pocket is reduced, results are typically lasting with a stable weight, and your doctor advises on maintenance and skin care.
For most people with a defined under-chin fat pocket, fat-dissolving injection is a common non-surgical option, contouring the area over a staged course. The right choice depends on whether the fullness is fat or laxity, which a doctor confirms. You can read more on our fat-dissolving injection page.

Fat-dissolving injection places a deoxycholic-acid-type lipolytic agent into the under-chin fat pocket, disrupting fat-cell membranes so the body clears them over weeks. The area becomes more defined gradually across a course. It contours a specific fat pad and is not a whole-body or facial weight-loss method.
You are likely suitable if you have a defined pocket of under-chin fat with reasonable skin tone, which the fat-dissolving injection targets. A consultation confirms whether the fullness is genuinely fat, since injections do not treat skin laxity or jaw structure. Your doctor tailors the plan to your anatomy.
Most patients feel a brief stinging or warm sensation during the injections, lasting only a few minutes as the small under-chin area is treated. Numbing is typically applied first to improve comfort. Mild tenderness afterward is normal and settles within a few days as the initial swelling subsides.
Expect swelling, tenderness, and sometimes mild bruising under the chin for about 3 to 7 days, peaking in the first 2 to 3 days. Many people return to daily activities quickly but plan social events around the initial swelling. Your doctor explains this timeline honestly before you begin.
Most people need a course of 2 to 4 sessions spaced about 4 to 6 weeks apart, since localized fat reduction builds gradually. The exact number depends on your fat volume and response. Your doctor confirms the plan on our treatment page and at consultation rather than treating everyone identically.
Visible contouring usually appears about 4 to 6 weeks after each session, once initial swelling settles and the body clears the treated fat. Improvement accumulates across the course, so the final refinement is judged a few weeks after your last session, not immediately after the first.
Once a fat pocket is reduced, the treated fat cells are cleared and results are typically lasting, provided your weight stays stable. Significant weight gain can enlarge remaining fat cells. Because this is localized contouring, maintaining results depends mainly on lifestyle rather than repeated sessions in the same spot.
No, it is localized contouring of a specific under-chin fat pocket, not systemic weight loss. It refines the chin and jawline but does not reduce overall body weight or replace diet and exercise. A doctor makes this distinction clear during consultation so your expectations are realistic.
If a doctor finds the fullness is mainly skin laxity, injections alone will not tighten it. In that case a skin-tightening approach, such as a non-surgical lifting option, may suit you better or be combined. This is why a proper assessment before treatment matters so much for a good outcome.
Yes, fat-dissolving injection is often combined with skin-tightening or lifting treatments when both fat and mild laxity are present, so the area looks contoured rather than soft. You can explore related contouring options. Your doctor plans any combination and its timing at consultation.
Common effects are localized: swelling, tenderness, bruising, numbness, and occasional firmness under the chin, mostly resolving within days to a couple of weeks. Your doctor reviews your medical history and screens contraindications first, and explains how these effects are minimized and managed, which is part of careful, quality care.
Aftercare is simple: avoid firm massage of the area for a day or two, keep the skin clean, and use cold compresses for swelling if advised. Most patients need no special products, though a supportive skin care routine can help. Our English-speaking team is available for questions between sessions.
For a single session, 1 to 2 days is comfortable, allowing a consultation, the injections, and a short check. Because treatment is a staged course, many international patients begin in Seoul and continue on return visits. Our English-speaking team helps coordinate timing around your travel plans.
Yes, flying within a day of a fat-dissolving session is generally fine, as it is a minimally invasive injection procedure. Expect some under-chin swelling during travel, so stay hydrated and follow aftercare advice. If you have any concerns, our English-speaking staff can advise you before you fly.
| Fat-Dissolving Injection | Chin Fat Freezing (Cryolipolysis) | Skin-Tightening Lifting | |
|---|---|---|---|
| Mechanism | Injected lipolytic agent breaks down localized fat cells | Controlled cooling reduces a fat pocket non-invasively | Ultrasound or RF energy tightens skin and builds collagen |
| Best for | A defined under-chin fat pocket with reasonable skin tone | A larger, pinchable fat bulge under the chin | Sagging or crepey skin rather than excess fat |
| Approach | Precise injections into the fat pad | An applicator cools the area for a set time | A handpiece delivers energy across the jawline |
| Downtime | Swelling and tenderness for a few days | Temporary numbness and redness | Usually minimal, occasional mild redness |
| Results timeline | Builds over several weeks per session | Gradual over weeks to a couple of months | Gradual as collagen remodels over months |
| Sessions | Often a course of 2 to 4 sessions | May need 1 to 2 cycles per area | Typically 1 session with periodic maintenance |
