Sagging Jawline Treatment in Korea: HIFU, RF, Threads & Boosters
The short answer
A sagging jawline is treated in Gangnam with HIFU to tighten the deeper layer under the jaw, RF to firm loose skin, thread lifts to reposition jowls, and sometimes fat-reducing injections or filler to sharpen the contour. HIFU typically costs about ₩100,000 to ₩3,000,000 and a jawline thread lift about ₩500,000 to ₩2,000,000. Results build over 2 to 3 months and usually last 6 to 18 months.

Why get a sagging jawline treated in Korea?
The jawline is often the first place where ageing shows. Jowls form as tissue descends, fat collects under the chin, and the clean angle between jaw and neck softens. Korean clinics are known for lower-face lifting, and Gangnam offers a wide range of devices and thread techniques focused on restoring a defined contour without surgery.
A doctor will usually assess skin laxity, fat under the chin, jaw bone structure, muscle bulk and neck bands. The right plan depends on whether your main issue is loose skin, descended tissue, extra fat or a lack of bony definition.
Types of jawline sagging treated
- Early softening: a slightly less crisp jawline.
- Jowls: tissue gathering beside the chin.
- Submental fullness: fat under the chin blurring the jaw angle.
- Neck laxity: loose skin that continues below the jaw.
- Structural softness: a small chin or jaw that needs support.
Most popular sagging jawline treatments in Korea
1. HIFU lifting
Focused ultrasound tightens the SMAS layer along the jaw and under the chin. See our lower face tightening page.
2. RF lifting
Radiofrequency firms skin along the jaw and neck.
3. Thread lift
Barbed threads lift jowls toward the ear for an immediate change. Read about jawline thread lifts.
4. Laser tightening
Fractional or infrared lasers improve skin quality over the area.
5. Skin boosters and collagen stimulators
Support firmness and skin thickness over time. Fat-dissolving injections may be added for under-chin fullness, and filler can sharpen the chin or jaw angle; see jawline contouring injections.

Why Gangnam?
Gangnam clinics routinely combine HIFU, RF and threads for the lower face, and many offer same-week appointments. For broader concerns, see our guides to sagging skin and marionette lines.
How many sessions are needed?
Premium HIFU and RF are usually one session a year; Korean HIFU may be repeated every 3 to 6 months. Thread lifts are a single procedure. Fat-dissolving injections often need 2 to 4 sessions. On a one-week trip, HIFU plus RF, or a thread lift with a check before you fly, is practical.
Aftercare
- Expect tenderness along the jaw for a few days after HIFU.
- After threads, avoid wide mouth opening, chewing gum and dental work for 2 weeks.
- Sleep on your back for several nights after threads.
- Skip saunas and intense exercise for 48 hours.
- Use SPF daily to protect collagen.

Can I combine lifting with fat reduction?
Yes. Fat-dissolving injections under the chin are often combined with HIFU for a sharper contour.
