Short answer:
A double chin can come from submental fat, loose skin, a short or recessed chin, or a combination. Small fat pockets respond to fat-dissolving injections or radiofrequency devices, loose skin to HIFU such as Shurink, larger fat volumes to face and neck liposuction, and a weak chin to filler. Fat-dissolving injections in Gangnam typically cost ₩100,000–₩400,000 (about $70–$290) per session, while face liposuction costs ₩2,000,000–₩5,000,000 (about $1,430–$3,570).
Find the cause first
- Submental fat:
soft fat you can pinch under the chin. Common even at a healthy weight and partly genetic.
- Skin laxity:
loose skin and platysma bands that hang when you look down, more common after 40.
- Chin and jaw structure:
a short or recessed chin makes any fullness under the jaw look bigger.
- Posture and angle:
looking down at phones exaggerates the look in photos.
A good consultation separates these factors, because the best treatment for fat is different from the best treatment for skin or bone.
Fat-dissolving injections
Injections containing fat-dissolving ingredients are placed into the fat under the chin, breaking down fat cell membranes. The body then clears the fat over several weeks. Most people need 2–4 sessions a few weeks apart. Expect swelling, tenderness and sometimes numbness for several days, so avoid scheduling them right before an event. Typical cost: ₩100,000–₩400,000 (about $70–$290) per session, versus about $1,200–$1,800 in the US.
Energy devices
- InMode (Forma and FX):
radiofrequency to tighten skin and reduce small fat deposits; ₩200,000–₩600,000 (about $140–$430).
- Shurink HIFU:
focused ultrasound that tightens tissue under the jaw; ₩150,000–₩500,000 (about $110–$360).
- Ultherapy:
deeper, imaging-guided HIFU; ₩800,000–₩2,500,000 (about $570–$1,790).
- Volnewmer and other RF devices:
tightening for mild laxity.
Devices have little downtime but results are gradual over 1–3 months.
Thread lifts
A V-line thread lift
places absorbable threads to lift sagging tissue along the jawline and under the chin. It suits mild to moderate laxity and costs about ₩800,000–₩2,000,000 (about $570–$1,430). Results typically last 1–2 years.
Face and neck liposuction
For larger fat volumes, a small cannula removes fat through tiny incisions behind the ears or under the chin. Results are more dramatic and permanent for the removed fat cells. Recovery includes a compression garment for 1–2 weeks, swelling for several weeks and a final shape at about 3 months. Typical cost: ₩2,000,000–₩5,000,000 (about $1,430–$3,570). Read liposuction vs injections.
Chin filler for profile
If the chin is short, adding projection with filler can transform the profile more than fat reduction alone. Chin filler
costs ₩200,000–₩600,000 (about $140–$430) and lasts roughly 12 months.
How to choose
- Mostly fat, good skin:
injections, InMode or liposuction.
- Loose skin:
HIFU, RF or threads, sometimes combined with fat reduction.
- Short chin:
chin filler, possibly combined with the above.
- Short trip:
devices with minimal downtime; leave injections or liposuction for longer stays.

Aftercare
- Avoid alcohol, saunas and intense exercise for a few days after injections.
- Wear compression garments exactly as instructed after liposuction.
- Maintain a stable weight to protect results.
Frequently asked questions
How many fat-dissolving sessions do I need?
Usually 2–4, a few weeks apart.
Is double chin liposuction permanent?
Removed fat cells do not return, but weight gain can still enlarge remaining fat.
Which option has the least downtime?
HIFU and InMode usually have the least.
Can I combine fat reduction and tightening?
Yes, many plans combine injections or liposuction with HIFU.
Does chin filler hide a double chin?
It can improve the profile significantly when the chin is short.
How much does double chin treatment cost in Gangnam?
From about ₩100,000–₩400,000 per injection session to ₩2,000,000–₩5,000,000 for liposuction.
