Double Chin Injections in Seoul (Hongdae): Fat-Dissolving Care
Double chin injections are fat-dissolving injections that break down small pockets of submental fat under the chin for a more defined jawline without surgery. They suit adults with a modest, pinchable double chin and good skin elasticity. Most people need a series of sessions, typically a few weeks apart, and a doctor confirms suitability.

How it works
Fat-dissolving injections usually contain deoxycholic acid or similar ingredients that disrupt the membranes of fat cells. Once damaged, those fat cells are gradually cleared by the body over the following weeks. Deoxycholic acid is the active ingredient in Kybella, which is FDA-approved for submental fat.
The doctor marks the area and injects small amounts in a grid pattern under the chin. You may feel burning or stinging for several minutes, and noticeable swelling, numbness or tenderness for several days is normal and a sign the product is working.
Because results develop gradually and usually require more than one session, it works best when you can return or continue care at home. If skin laxity is the main issue, lifting treatments may be combined.
How it compares
| Compared with | Difference |
|---|---|
| Liposuction | Liposuction removes more fat in one procedure but is surgical, while injections are non-surgical and need a few sessions. |
| HIFU lifting | HIFU devices such as Shurink or Ultherapy mainly tighten and lift skin, while injections reduce the fat itself. |

Frequently asked questions
How much do double chin injections cost in Seoul?
Cost depends on the product used, the amount needed and the number of sessions. Message us on WhatsApp with a side-profile photo, and the doctor confirms a plan and exact quote at consultation before treatment. Because every face and skin type is different, the doctor confirms what is suitable for you during your consultation, and results vary from person to person.
Does it hurt?
Most people feel burning or stinging for several minutes after injection. Numbing cream or ice helps. Tenderness and swelling are common for several days afterward and are usually manageable. If you are visiting Seoul for a short time, tell us your travel dates when you book so the doctor can plan treatment timing around your flight.
How much swelling should I expect?
Swelling under the chin is normal and can be noticeable for several days to about a week, especially after the first session. Plan treatment so it does not clash with important events or photos. Our English-speaking team can answer follow-up questions on WhatsApp or KakaoTalk before your visit and after you return home.
How many sessions do I need?
Most people need 2 to 4 sessions spaced a few weeks apart, depending on the amount of fat and the product used. Results vary, and the doctor will suggest a realistic plan for your schedule in Korea. The doctor will also review your medical history, current medications and any previous treatments before recommending anything.
Are the results permanent?
Fat cells that are destroyed do not regrow, so results can be long-lasting if your weight stays stable. Significant weight gain can still enlarge remaining fat cells. Written aftercare instructions in English are provided, and you can message us any time if something does not feel right.
Can I fly after double chin injections?
Flying is generally fine. Swelling may feel more noticeable on a long flight, so stay hydrated and avoid alcohol. Message us on WhatsApp if you have any concerns once home. Booking early in your trip also leaves time for a quick check with the doctor before you leave Korea, if one is needed.

Double Chin Injections in Hongdae – Define Your Jawline & Eliminate Submental Fat
Struggling with a double chin that won’t go away no matter how much you diet or exercise? Double chin injections are a safe, non-surgical solution designed to dissolve stubborn fat beneath the chin and contour your jawline. At our clinic in Hongdae, we offer targeted fat-dissolving treatments to help you achieve a more defined, sculpted facial profile—without surgery or downtime.
What Are Double Chin Injections?
Double chin injections (also known as injection lipolysis) use a fat-dissolving solution—typically deoxycholic acid or phosphatidylcholine—to break down and eliminate submental fat cells. Once destroyed, these fat cells are naturally metabolized by the body and do not return.
This treatment is ideal for:
- Reducing fullness beneath the chin
- Creating a sharper, more sculpted jawline
- Improving side-profile balance
- Enhancing facial definition without invasive surgery
Why Choose Double Chin Injections?
Key Benefits:
✅ Permanently reduces submental fat cells
✅ Non-surgical and minimally invasive
✅ No general anesthesia or incisions
✅ Quick procedure (typically under 30 minutes)
✅ Gradual, natural-looking results
✅ Boosts overall facial harmony and confidence
How the Treatment Works
- Consultation & Mapping
Your provider will assess your chin and jawline and map out injection points. - Injection Session
A fine needle is used to inject the fat-dissolving solution directly into the submental area. Numbing cream or ice packs may be applied beforehand to minimize discomfort. - Fat Breakdown & Elimination
Over the following weeks, the solution breaks down the fat, which is gradually eliminated through the body’s lymphatic system.
Each session typically lasts 20–30 minutes, with 2 to 4 sessions spaced 3–6 weeks apart recommended for optimal results.
What to Expect After Treatment
Mild to moderate swelling, redness, or tenderness under the chin is common and may last 3–7 days. Some patients experience minor bruising or firmness, which resolves as healing progresses.
You can resume most daily activities right away, but strenuous exercise and alcohol should be avoided for 24 hours post-treatment.
Who Is a Good Candidate?
You may benefit from double chin injections if:
- You have mild to moderate fat under the chin
- You are at or near your ideal weight
- You want to avoid surgery or downtime
- You seek gradual, natural-looking contour improvement
- You are in good overall health and have realistic expectations
This treatment is not recommended for individuals with loose, sagging skin under the chin (in that case, skin tightening treatments may be better suited).
How Long Do Results Last?
Once the fat cells are destroyed, they do not return. Results become visible after 4 to 6 weeks and continue to improve with each session. A full treatment series can provide permanent contouring, especially when combined with a healthy lifestyle.
