Double Chin Treatment in Korea: Liposuction, Injections and Devices
The short answer
A double chin in Korea is treated with chin liposuction for a one-time, long-lasting result, fat-dissolving injections over several sessions, or energy-based skin tightening for loose skin. Chin liposuction takes about 30 to 60 minutes and typically costs ₩1,500,000 to ₩4,000,000 in 2026. Injections cost about ₩100,000 to ₩300,000 per session, usually 2 to 4 sessions.

- Skin tightening: HIFU or RF, ₩300,000–₩2,000,000
- Downtime: 1–3 days (injections) to about 1 week (liposuction)
- Longevity: long-term if weight stays stable
What is a double chin?
A double chin is a layer of fat or loose skin beneath the chin that blurs the line between the jaw and neck. It can appear at any weight; genetics, a small chin, posture and ageing all play a part. It is one of the most common concerns at Gangnam clinics because it affects both the front view and profile.
What causes it?
- Submental fat: fat that collects under the chin, often resistant to diet.
- Skin laxity: loose skin with age or after weight loss.
- Weak chin or low hyoid position: structural features that make the neck angle less sharp.
- Weight gain: more fat across the face and neck.
Treatment options in Korea
1. Chin liposuction
A thin cannula through tiny openings under the chin and sometimes behind the earlobes removes fat precisely. It is quick, usually done under local anesthesia or sedation, and the fat cells removed do not return. A compression band is worn for several days. It suits moderate fat with good skin quality.
2. Fat-dissolving injections
Injectable solutions break down fat cells, which the body then clears. Each session is quick, with swelling for 1 to 3 days. Most people need 2 to 4 sessions spaced 2 to 4 weeks apart. See fat-dissolving injections and double chin reduction.
3. Energy-based skin tightening
HIFU and RF devices heat deep tissue to tighten skin and stimulate collagen. They help with mild laxity and often follow liposuction or injections to improve the result.
4. Combination treatments
Many plans combine approaches: liposuction plus tightening, or injections plus chin filler to strengthen a weak chin. When skin is very loose, a neck lift may be the better choice.

Risks to discuss
After liposuction, ask about unevenness, loose skin if too much fat is removed, temporary numbness, firm lumps during healing and, rarely, weakness of the lower lip from nerve irritation. After injections, swelling can be marked for a few days, and some people feel tenderness or numbness under the chin. Devices can cause temporary redness or tenderness. Ask your doctor which option suits your skin quality and age.
Why patients choose Korea
Chin liposuction and fat-dissolving injections are performed very often in Gangnam, and clinics are used to treating visitors on short schedules. Prices are generally competitive, and many clinics combine body and face fat reduction in one plan.
Planning your trip
- Injections: you may need to return for later sessions, so liposuction can be more practical for one trip.
- Liposuction: plan 5 to 7 days in Seoul and pack scarves or high collars for the compression band.
- Devices: no downtime; good to combine with other treatments.
Aftercare
After liposuction, wear the chin band as directed, sleep with your head raised and avoid saunas for two weeks. After injections, expect swelling and a firm feeling for a few days. Keep your weight stable to maintain results.
Questions to ask at consultation
Ask whether your double chin is mainly fat, loose skin or chin shape, and which option addresses that cause. For liposuction, ask how long the chin band is worn and when you can fly. For injections, ask how many sessions you will likely need and whether they can be spaced around your travel.

Patient questions
Frequently asked questions
Which works better, liposuction or injections?
Liposuction gives a bigger change in one session. Injections suit smaller amounts and need several visits.
Will the fat come back?
Removed fat cells do not return, but remaining cells can grow if you gain weight.
Can a double chin be caused by a weak chin?
Yes. Adding chin projection can improve the neck angle alongside fat reduction.
How long is swelling after chin liposuction?
Most swelling settles in 1 to 2 weeks; final results show at about 3 months.
