Double Chin Treatment in Seoul

Home › Cosmetic Dermatology › Double Chin Treatment

Double chin treatment is any procedure that reduces the fullness beneath the chin, known medically as submental fat, to restore a cleaner line between the chin and neck. At Yaan Clinic in Gangnam, Seoul, the main non-surgical option is the Double-Chin Package, a Yaan Signature program that pairs an energy device with an injection so fat is targeted in two complementary ways.

A double chin is not only a weight issue. Genetics, posture, aging skin and the shape of the jaw all play a part, which is why slim people often have one too.

What is Yaan Clinic's Double-Chin Package?

The Double-Chin Package combines TUNELINER, a 3D ultrasound applicator that targets fat, with Yaan Clinic's fat-dissolving injection. It is listed on Yaan's 2026 price list as a Yaan Signature treatment.

TUNELINER

TUNELINER (Tune Liner) is an applicator of the Accent Prime platform by Alma Lasers, the same system behind Yaan's TuneFace lifting. Yaan describes it as 3D ultrasound for fat breakdown. Yaan Clinic is an Alma Elite Club partner clinic.

Fat-dissolving injection

The injection uses Yaan's Body Sculpture Injection, a fat-dissolving formula registered with the Korean Intellectual Property Office and exclusive to Yaan. It breaks down fat cell membranes so the fat is converted into a water-soluble form and cleared naturally. The patented Protecter skin protector, developed by Yaan's medical team, is used to reduce irritation at injection points.

How does non-surgical double chin treatment work?

Ultrasound energy from TUNELINER heats and disrupts fat under the chin, while the injection breaks down fat cells directly. Together they aim to reduce volume more evenly than either step alone.

Because the chin area is small and close to the jawline, precision matters. Your doctor assesses how much of the fullness is fat, how much is loose skin and how much comes from jaw or muscle structure. This decides whether the package alone is enough or whether a lifting or Botox treatment should be added.

Which double chin treatment is right for me?

If the fullness is mainly fat, the Double-Chin Package is the most direct option. If loose skin is the bigger issue, an ultrasound or RF lifting treatment may help more. A wide jaw from muscle responds to jawline Botox.

Main cause	Option at Yaan Clinic	What it does
Fat under the chin	Double-Chin Package (TUNELINER + injection)	Reduces submental fat in two ways
Fat plus mild sagging	Ulthera Fit (Ultherapy Prime + Tune Liner + LDM) or Sofwave Fit	Lifts and tightens while addressing fat; see Ultherapy Prime
Loose skin, little fat	Sofwave, Thermage FLX or other lifting	Tightens skin and stimulates collagen
Wide, muscular jaw	Jawline Botox(Xeomin)	Slims the masseter muscle for a narrower lower face

Many people have more than one cause. Your doctor will explain which combination fits your face at consultation; see also square jaw and face slimming.

Double chin package vs liposuction: what is the difference?

Chin liposuction removes fat surgically through small incisions and needs recovery time. Yaan's package is non-surgical, uses local anesthesia for the injection, and lets you return to daily activities straight away.

Surgery can remove more fat in one go, but involves anesthesia, a compression strap for a period and higher cost and risk. The non-surgical route works gradually and is usually done as a short course, which is why Yaan offers a three-session option.

Is double chin treatment painful? What is the downtime?

The injection area is numbed with local anesthesia, and TUNELINER typically feels warm. Most people return to daily activities the same day without a compression garment.

As with most fat-dissolving treatments, swelling, tenderness or a firm feeling under the chin is common for several days, and small bruises can appear. These usually settle without treatment. Your doctor will confirm aftercare and when to resume exercise.

Who is a good candidate?

Good candidates have a soft pocket of fat under the chin, reasonably good skin elasticity and a stable weight. The package also suits slimmer people whose double chin persists despite diet and exercise.

• Fullness under the chin in photos or when looking down
• A jawline that has lost definition
• People who want a non-surgical, low-downtime option
• People willing to complete a course of sessions for gradual results

What happens at your appointment?

1. Consultation and assessment – the doctor checks fat, skin laxity and jaw structure, and may use 3D Meta-Vu skin analysis.
2. Plan – you choose a single session or the three-session package, with or without lifting add-ons.
3. TUNELINER – ultrasound is applied under the chin and along the jawline.
4. Fat-dissolving injection – after local anesthesia and Protecter, the Body Sculpture Injection is placed into the fat.
5. Aftercare – you receive instructions for the following days and your next session date.
