REPIC Clinic Myeongdong — 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 Myeongdong clinic a consultant goes through your concern with you, and the Mark-Vu/Meta-Vu scan and report set the plan from there.
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.
