A double chin can come from fat, loose skin, muscle or bone structure, and each cause has a different treatment and price. This guide compares double chin options in Seoul and what they cost.

What causes a double chin?
Before choosing a treatment, it helps to know what is behind the fullness. A doctor usually checks four things:
- Fat under the chin. A soft pocket of fat that you can pinch. Injections and fat-targeting devices work best here.
- Loose skin. Skin that has lost firmness and sags below the jaw. Lifting and tightening devices suit this.
- Muscle bands. Prominent neck muscle bands can add to an undefined neck line.
- Jaw and chin structure. A small or set-back chin can make the area look fuller even at a healthy weight. Filler may help define the chin.
Most people have a mix of causes. That is why a quick in-person exam matters more than choosing a treatment online. See double chin treatments for an overview.
Fat-dissolving injections: cost and what to expect
Fat-dissolving injections use an injectable solution that breaks down small pockets of fat. Your body then clears the treated fat gradually over several weeks. At Dernia, one facial area costs ₩69,000 per session, two facial areas cost ₩129,000 and a three-session course for one area costs ₩189,000.
- Sessions: usually two to four, two to four weeks apart.
- Downtime: swelling for two to five days is common, sometimes with tenderness, bruising or numbness.
- Risks: rarely, nerve irritation that affects the smile temporarily, lumps or uneven results. Several formulations exist in Korea, and your doctor explains which one they recommend and why.

Devices for a double chin: InMode, ONDA and HIFU
InMode Mini FX
Mini FX uses radiofrequency to target small fat pockets under the chin and along the jowls, often combined with Forma to tighten skin. At Dernia, one area costs ₩129,000 per session, and Forma full face with Mini FX costs ₩279,000. It works best as a series of about three to five sessions.
ONDA Lifting
ONDA uses microwave energy to heat fat and deeper tissue. Under the chin or along the jawline, 30,000 J costs ₩199,000, and a full lower-face plan of 60,000 J costs ₩349,000. Results build over four to eight weeks.
Shurink Universe and Ulthera Prime
If loose skin is the main issue, focused ultrasound can tighten the area under the chin. Shurink Universe costs ₩149,000 for 300 shots, and Ulthera Prime costs ₩390,000 for 100 lines, a plan designed for one area such as under the chin.
Compare devices in ONDA vs InMode lifting.
Injections vs devices: how they compare
Injections are the lowest-cost option per session and work directly on fat, but they usually cause noticeable swelling and need repeat visits. Devices cost more per session, involve no needles and often have little visible downtime, which suits a short trip. Results from both appear gradually over weeks rather than overnight. If your skin is already loose, removing fat alone can leave the area looking softer rather than sharper, so tightening may need to be part of the plan.
Does Botox help a double chin?
Botox is not a primary double chin treatment, because it does not remove fat or tighten loose skin. It is sometimes used for related concerns. Jaw Botox relaxes a bulky masseter muscle to slim a square lower face, starting from ₩59,000 for both sides with a Korean toxin at Dernia. In some cases, a doctor may discuss toxin for prominent neck bands. If your concern is a wide jaw rather than fullness under the chin, compare options in jaw Botox vs fat-dissolving injections.
Which double chin treatment is right for you?
Usually a good fit
- Pinchable fat: fat-dissolving injections, ONDA or Mini FX
- Mild loose skin: Shurink Universe or Ulthera Prime
- Fat plus laxity: a device combined with tightening
- A small chin: chin filler may be discussed
Talk to the doctor first
- Heavy sagging or a lot of excess skin
- Thyroid problems or a lump in the neck
- Pregnancy or breastfeeding
- Bleeding disorders or blood thinners (for injections)
A doctor checks for medical causes of neck swelling before treating anything cosmetically.
How much should you budget overall?
For a small fat pocket, a three-session injection course at ₩189,000 is often the most economical route, but it requires repeat visits two to four weeks apart. For visitors who can only come once, a single device session such as ONDA at ₩199,000 for 30,000 J, or Shurink Universe at ₩149,000 for 300 shots, may be easier to fit into a trip. When fat and laxity are both present, a combination may be suggested. The V-Line Contour package is designed for lower-face contouring.

What happens at your double chin consultation?
- Exam. A licensed doctor checks the area while you look straight ahead and down, pinches the tissue to judge fat versus skin, and looks at your jaw and chin profile.
- Plan. The doctor explains which treatment, how many sessions and the total price in English.
- Treatment. Injections take about 15–20 minutes; devices take 20–45 minutes depending on the area.
- Aftercare. You receive written instructions and know who to contact if anything feels unusual.
Planning double chin treatment around your Seoul trip
- Book ahead. Send your dates and photos of your profile through our consultation form.
- Allow for swelling. After injections, swelling under the chin can last two to five days. Schedule early in your trip.
- Avoid your arrival day. Most visitors book from day two.
- Getting here. Dernia is in Myeongdong, near Myeongdong Station (Line 4) and Euljiro 1-ga Station (Line 2).
Flying home? Devices rarely affect flying. After fat-dissolving injections, swelling can be more noticeable for a few days, so plan treatment early in your stay. See our aftercare guide.
