Double Chin Treatment in Seoul – Diagnosis by Board-Certified Dermatologists

A double chin is a fullness under the jaw caused by submental fat, loose skin, or both, sometimes influenced by genetics and jaw structure rather than weight. At The Heal Dermatology Sinsa Main Branch in Gangnam, Seoul, board-certified dermatologists assess fat and skin laxity and may recommend radiofrequency contouring such as InMode, tightening devices or other options.

What causes a double chin

Submental fullness may come from localised fat that resists diet and exercise, genetic fat distribution, skin laxity with age, weight gain, or a small or recessed chin. Posture, such as looking down at phones, can make it look more prominent in photos.

How a dermatologist diagnoses it

A dermatologist examines the area while you look forward and down, pinches to estimate fat thickness, checks skin elasticity and looks at chin and jaw structure. Swollen glands or thyroid enlargement are excluded when relevant, because they need medical evaluation rather than cosmetic treatment.

Treatment options at The Heal Sinsa

Options may include radiofrequency fat reduction and tightening with InMode Forma/FX, skin tightening with Oligio or Shurink Universe, and contour support from chin filler when a small chin is a factor. Fat-dissolving injections may be discussed where appropriate. Availability of specific devices varies by branch – confirm at consultation. Every plan starts with a 1:1 consultation with a Korean board-certified dermatologist and imaging-based skin analysis; you will not be pushed toward treatment you do not need. Pricing is confirmed after consultation; see pricing and payment.

Sessions, downtime & side effects

  • Radiofrequency contouring: typically several sessions for a visible effect
  • Mild redness, swelling or tenderness for a few days
  • Results build gradually over weeks to months
  • Avoid during pregnancy, with active infection or with certain implanted devices

Home care

Maintaining a stable, healthy weight and good posture helps. Neck and chin exercises have limited evidence. Use sunscreen on the neck as well as the face, as sun damage contributes to laxity.

When to see a doctor

See a dermatologist if submental fullness bothers you despite healthy habits. Seek medical advice promptly if there is a new lump, tenderness, swelling that comes and goes, or difficulty swallowing.

Planning around your trip to Seoul

Most contouring devices allow normal activity the same day, so a session fits a city trip; ask about combining treatments in one visit through our combining treatments guide. The clinic is on the 7th floor of Sinsa Square near Sinsa Station, close to Garosu-gil (getting here), and English support is available on request (international patients).

Frequently asked questions

Can a double chin be reduced without surgery?

Often, yes. Radiofrequency devices, skin tightening and sometimes fat-reducing injections can improve mild to moderate fullness. Results are gradual. Large amounts of fat or very loose skin may respond better to surgical options.

Will losing weight get rid of a double chin?

Weight loss can help if fullness is due to overall body fat, but some people have genetic submental fat or skin laxity that remains. A dermatologist can assess which factor is most significant for you.

How many sessions are needed?

It depends on fat thickness, skin quality and the method used. Radiofrequency contouring often needs several sessions, while tightening devices may need one or two. Your dermatologist will suggest a plan at consultation.
