REPIC Clinic Gangnam — Dermatology Clinic
Double chin and jawline
A soft jawline can be fat, loose skin, jaw muscle, a short chin or enlarged salivary glands. Some need reducing, some need tightening, and one needs neither.
What usually causes it
- 01
Fat under the chin
Fat under the chin can be there at a normal body weight. Reducing it shows the jawline that was hiding.
How we tell them apart
- Pinching under the chin gives a thick, soft fold
- It is there whether you look down or straight ahead
- It did not change much with weight loss
What we'd suggest, by cause
V-Olet
Fat-dissolving injection.
ONDA
Microwave energy for fat plus some tightening.
Inmode Lifting
- 02
Loose skin
Little fat, but the skin has lost its hold and hangs. Reducing fat here makes it worse. The skin needs tightening.
How we tell them apart
- The pinch is thin and loose, not thick
- Worse when you look down, better when you lift your chin
- Neck lines and crepey texture
What we'd suggest, by cause
Ultherapy / Ultherapy Prime
Shurink Universe
Thermage FLX
- 03
Jaw muscle and chin structure
A wide masseter muscle squares the jaw. A short or recessed chin lets the neck skin fold. Neither is fat.
How we tell them apart
- The sides of the jaw bulge when you clench your teeth
- You grind or clench at night
- In profile, the chin sits behind the lips
What we'd suggest, by cause
Jawline Botox
Slims the masseter over time.
3D Design Filler (chin)
A little chin projection sharpens the whole jawline.
- 04
Enlarged salivary glands
The glands below the jaw angle can be enlarged, giving a fullness that looks like fat but is not. Fat treatment does nothing here.
How we tell them apart
- Fullness sits just under the jaw angle, on both sides
- Does not change with weight
- Firmer than fat when pressed
What we'd suggest, by cause
Diagnosis comes first
What we look for first is the pinch test and the clench test. A thick pinch is fat; a thin, loose pinch is skin. If the sides of the jaw bulge when you clench, it is muscle. A soft fullness just below the jaw angle that does not change with weight can be the salivary gland.
At the Gangnam clinic a doctor examines your skin in person first. Then a Mark-Vu/Meta-Vu scan and the RSTI report put numbers on what they saw. The plan is built from both, not from the name of the treatment you came in asking for.
Good to know
- Fat plus loose skin is common. Reduce fat first, then tighten, or you are tightening over bulk.
- Fat-dissolving injections swell for a while before they shrink. Do not book it the day before photos or a flight.
- Muscle Botox works gradually, and the jaw can feel tired when chewing at first.
Common questions
Is it fat or skin?
Pinch it. Thick and soft is fat; thin and loose is skin. Many people are both, and the scan and exam settle it.
Fat-dissolving or Ultherapy?
V-Olet reduces fat. Ultherapy tightens the skin and the layer under it. Fat-only cases lean V-Olet, loose-skin cases lean Ultherapy, and mixed cases get both in sequence.
Can I do this before flying home?
Ultherapy and Shurink: minimal downtime. V-Olet: expect swelling for a while. Botox: none. We order the steps around your dates.
Other concerns
Results vary from person to person. A doctor decides on treatment after examining you, and nothing on this page is a promise of outcome.
