Double Chin Reduction in Seoul: Slimmer Profile Without Surgery
The short answer
Double chin reduction in Seoul removes submental fat with fat-dissolving injections or cryolipolysis and tightens the skin above it with HIFU or RF. Injections typically cost ₩100,000–₩400,000 per session, with two to four sessions four weeks apart. Swelling lasts three to seven days. Destroyed fat cells do not return, so results last long if your weight stays stable.

What causes a double chin
A double chin, or submental fullness, usually comes from a combination of fat under the chin and loosening skin. Genetics play a large role, which is why slim people can still have one. Ageing, weight gain, posture and a naturally short or recessed chin can make it more visible, especially in side-profile photos.
The best treatment depends on which factor dominates. A doctor will assess how much you can pinch, how firm the skin is, and the shape of your jaw and chin.
Fat reduction options
Fat-dissolving injections
Deoxycholic acid or Korean fat-dissolving formulas are injected in a grid under the chin. They break down fat cells, which the body clears over several weeks. Expect noticeable swelling for three to seven days, especially after the first session. Our injection lipolysis page explains the different solutions.
Cryolipolysis
A small applicator freezes the fat under the chin. It suits a clear, pinchable pocket and causes less swelling than injections, though the area may feel numb for a few weeks.
Skin tightening options
When the skin is loose, removing fat alone can leave a softer look. HIFU and RF tighten the skin and support the jaw-neck angle. These are often done in the same visit as injections or in a separate session. See our neck tightening guide for more.
| Main issue | Usual plan | Sessions |
|---|---|---|
| Mostly fat | Fat-dissolving injections or cryolipolysis | 2–4 |
| Fat plus mild loose skin | Injections plus HIFU or RF | 2–4 plus 1 |
| Mostly loose skin | HIFU, RF or threads | 1–2 |
| Large volume or heavy skin | Liposuction or surgery | 1 |
What to expect
Injections take 10–20 minutes after numbing. You will feel stinging and warmth, then swelling over the next day. Many patients look puffier before they look slimmer, so schedule around important events. HIFU and RF have little visible downtime.
Results
Each injection session reduces fat gradually. Most people see a clearer jawline after two or three sessions, with the full effect about eight to twelve weeks after the last one. Because treated fat cells are destroyed, results are long-lasting as long as your weight stays stable. Tightening results typically last 6–12 months.
Side effects
- Swelling, tenderness and numbness are common after injections
- Bruising and temporary firmness under the skin
- Rarely, temporary nerve irritation affecting the smile; ask your doctor how they avoid this
Planning as a visitor
Because swelling peaks for a few days, try to have injections early in your trip. Flying is fine, but you may want to avoid tight collars. Since sessions are about four weeks apart, many visitors complete one session per trip and combine it with HIFU for an immediate improvement in definition. For a broader contour plan, see jawline tightening.
