Sagging Neck Treatment in Cheongdam & Apgujeong, Seoul

What makes the neck sag?

A youthful neck has a crisp angle between the jawline and the neck, with smooth skin following it closely. Several layers maintain that shape, and each can fail separately.

• Skin. Collagen and elastin decline with age and sun exposure, so neck skin loses its ability to spring back and begins to drape.
• Fat. Fat beneath the chin (submental fat) blurs the jaw-neck angle. It can be genetic and present at any weight, or increase with weight gain and age.
• Muscle. The platysma, a thin muscle sheet across the neck, loosens over time. Its front edges can separate and show as vertical bands, sometimes called a turkey neck when combined with loose skin.
• Jawline support. As the cheeks and jowls descend and the jawbone gradually loses some volume, the lower border of the face becomes less defined, and the neck appears to start higher than it should.
• Anatomy. A naturally low-set hyoid bone or a smaller chin can give a softer jaw-neck angle from a young age.

Most people with a sagging neck have two or more of these factors. A neck that is mainly fat behaves very differently from one that is mainly loose skin, which is why the same treatment can work well for one person and disappoint another.

How Doje Clinic assesses the neck

In a 1:1 consultation, Dr. Byun Jeik, a surgery specialist trained at Seoul National University, examines the neck from the front and side, at rest and with the head tilted, and asks you to tense the neck muscles. He gently pinches the area under the chin to judge how much is fat and how much is skin, and assesses how far the jowls and lower face contribute.

Doje’s Jawline Program was designed around exactly these three variables — structural sagging, subcutaneous fat and skin elasticity — so the plan reflects your particular combination rather than a fixed package.

Options from mild to advanced

1. Skin quality and mild tightening. For early laxity, Ultherapy Prime or Thermage stimulate collagen in targeted layers, with change building over months.
2. Reducing fat. Where submental fullness is moderate, ONDA microwave technology is used for fat and contour. When fat is more pronounced, double-chin liposuction removes it directly.
3. Restoring the jawline. A Doje signature lower-face thread lift repositions jowls and redefines the lower border of the face, which sharpens the jaw-neck transition.
4. Structural support. Radiesse along the jawline may be considered to add definition while stimulating collagen.
5. Muscle bands. Botox may soften visible platysma bands in suitable patients.

These are combined only as far as needed. Someone with good skin and isolated fat may need only fat reduction; someone with loose skin and little fat may benefit more from lifting and tightening.

Where Doje’s programs fit

The Jawline Program is the natural home for a sagging neck: a lower-face thread lift and double-chin liposuction as core items, with Radiesse, Ultherapy Prime or ONDA as options. When neck sagging is part of wider facial ageing, the Signature Program plans the whole face.

When a surgeon is the right call

If loose neck skin hangs in folds, or platysma bands are very prominent, non-surgical treatments are unlikely to meet your goals. A plastic surgeon can advise on a surgical neck lift. Doje does not perform surgical neck lifts and will tell you honestly if that is the more appropriate route.

What to expect

1. 1:1 consultation and layer-by-layer neck assessment.
2. A plan prioritising the dominant factor.
3. Treatment; swelling and bruising vary, and liposuction needs more recovery than device treatments.
4. Review as tightening and contour settle over weeks to months.

Cost

Costs depend on which items your plan includes, so they are quoted after a 1:1 consultation. Korean aesthetic fees are non-covered (비급여); ask for a written quote.

Frequently asked questions

Is a sagging neck caused by fat or loose skin?

Often both, plus muscle laxity and jawline changes. Pinching and dynamic examination at consultation help separate them.

Can a thread lift help the neck?

A lower-face thread lift redefines the jawline, which often improves the jaw-neck angle. It does not remove fat or excess neck skin.

Liposuction or ONDA for a double chin?

ONDA may suit moderate fullness, while liposuction is considered for more pronounced fat. The choice depends on fat volume and skin elasticity.

Will tightening devices fix turkey neck?

Devices can improve mild to moderate laxity. Heavy hanging skin and prominent bands are usually better assessed by a surgeon.

What is the recovery like?

Device treatments usually have little downtime; thread lifts and liposuction involve swelling and bruising that vary between people.

How much does treatment cost?

It is quoted after a 1:1 consultation. Korean aesthetic fees are non-covered and set per plan, so request a written quote.
