🌸 Quick answer

How do you get rid of a double chin without surgery? It depends on the cause. If the fullness is fat, fat-dissolving injections break down the fat cells over a few sessions. If it is loose skin, HIFU, RF or thread lifting tighten and lift the area. Many people have a mix, so a doctor assesses whether fat, skin laxity or muscle bands are behind it and tailors the plan. Non-surgical results build over 4–12 weeks; liposuction is an option for larger fat pockets.

What causes a double chin, and how is it treated?

A double chin — submental fullness — can come from excess fat under the chin, skin laxity with age, loose platysma muscle bands, or a less defined jawline that makes any fullness look more prominent. Because the causes differ, the right treatment depends on an accurate assessment rather than one fixed solution.

Non-surgical options include fat-dissolving injections for fat, HIFU or RF for skin tightening, and thread lifting for sagging. Where there is a large fat pocket or significant sagging, surgical liposuction or a neck lift may be discussed.

Why it happens

  • Excess submental fat (genetic or weight)
  • Skin laxity or sagging with age
  • Loose platysma muscle bands
  • Less defined jawline or bone structure

Treatment options

  • Fat-dissolving injections for fat
  • HIFU / ultrasound for lifting
  • RF microneedling or RF for tightening
  • Thread lifting for sagging
  • Liposuction for larger fat pockets

Before & after: what changes

As fat reduces and skin tightens, the jawline looks sharper and the under-chin smoother over several weeks.

Who is double chin treatment for?

A good option if you

  • Have mild to moderate fullness under the chin
  • Want a sharper jawline without surgery
  • Have a double chin despite being slim
  • Have early skin laxity under the chin
  • Prefer a gradual, natural change

Less suitable if you

  • Have a very large fat pocket (consider liposuction)
  • Have significant loose skin and muscle bands needing a surgical neck lift
  • Have an active infection in the area
  • Expect one session to remove it all

How double chin treatment works

  1. Assessment

    The doctor checks whether the fullness is fat, skin laxity, muscle bands or a combination, then recommends the approach.

  2. Tailored plan

    Fat is targeted with injections, laxity with energy devices, and sagging with threads — often combined for best effect.

  3. Treatment session

    A non-surgical session usually takes 10–40 minutes; several sessions may be needed for injections or RF microneedling.

  4. Gradual change

    Fat reduces and skin tightens over 4–12 weeks as the area remodels.

Recovery and results timeline

Non-surgical downtime is usually mild — fat-dissolving injections may cause swelling for 1–3 days, HIFU and RF brief redness. Most people return to normal activities the same day.

  1. Same day Back to normal activities
  2. 1–3 days Any swelling settles
  3. 4–12 weeks Progressive slimming and tightening
  4. Ongoing Maintained as needed

Double Chin Treatments FAQ

How much does double chin treatment cost in Seoul?

Fat-dissolving injections run about ₩100,000–₩300,000 per session and HIFU or RF ₩200,000–₩1,500,000; surgical liposuction is ₩1,000,000–₩2,500,000. International patients pay the same local price.

How many sessions will I need?

Fat-dissolving injections and RF usually need 2–4 sessions spaced a few weeks apart, while a single surgical procedure removes fat in one step. Your doctor will confirm a plan.

Does fat-dissolving injection hurt?

You may feel stinging and warmth during the injection, and swelling for a day or two afterwards. Numbing cream is used to keep it comfortable.

Will the fat come back?

The treated fat cells are reduced, but significant weight gain can add new fullness. Keeping a stable weight helps results last.

Fat-dissolving or HIFU — which do I need?

Fat-dissolving injections target fat, while HIFU and RF tighten loose skin. Many people need both; a doctor decides based on what is causing the fullness.

Can I treat a double chin on a short trip?

Yes for non-surgical options, though a full course of injections may need more than one visit or a return trip to complete.
