Double Chin Reduction in Seomyeon, Busan

Double chin reduction (이중턱 개선) treats fullness under the chin using non-surgical options such as deoxycholic acid injections, cryolipolysis or HIFU, or surgical chin liposuction for larger fat pockets. In Seomyeon, Busan, injection sessions take about 20–30 minutes, often repeated 2–4 times; chin liposuction takes about an hour under local anesthesia. The right option depends on fat amount, skin laxity and anatomy.

What is double chin reduction?

A double chin can come from several factors: fat under the chin, loose skin, a small or set-back chin bone, low hyoid position, enlarged salivary glands or muscle bands. Each needs a different solution. Fat-focused treatments include:

  • Deoxycholic acid injections: destroy fat cells over several sessions.
  • Cryolipolysis: a small applicator freezes submental fat.
  • HIFU or radiofrequency: mainly tighten skin and may reduce small amounts of fat.
  • Liposuction: removes larger amounts of fat through a tiny incision under the chin.

If the chin bone is small, chin augmentation (implant, filler or genioplasty) may improve the profile more than fat reduction.

Who is it for?

  • People with pinchable fat under the chin, at or near a stable weight
  • Those wanting a defined jawline in profile
  • Good skin elasticity for fat-only treatments

Significant loose skin may need a neck lift. Thyroid swelling or a new neck lump should be medically checked before any cosmetic treatment.

What happens at the clinic

  1. Assessment: the doctor examines fat, skin, muscle and chin projection in profile.
  2. Option discussion: injections, devices or liposuction based on anatomy and downtime preference.
  3. Treatment: injections in a marked grid, a device cycle, or liposuction under local anesthesia.
  4. Aftercare: cold packs, and a chin strap after liposuction.
  5. Review: results assessed after several weeks before further sessions.

Recovery and aftercare

Injections typically cause notable swelling, numbness and tenderness for several days. Cryolipolysis may cause temporary numbness and fullness. After liposuction, wear the compression strap as directed and expect swelling and bruising for 1–2 weeks. Final results appear over 1–3 months.

Risks and side effects

  • Swelling, bruising, numbness, firmness
  • Rare temporary marginal mandibular nerve weakness, causing an uneven smile
  • Irregular contours or skin laxity after fat removal
  • Difficulty swallowing temporarily after injections (uncommon)
  • Paradoxical fat growth after cryolipolysis (rare)

Choosing a clinic for double chin reduction in Seomyeon

  • Choose a physician who identifies whether fat, skin, bone or glands cause your double chin.
  • Ask which approved product or device is used.
  • Ask how they avoid nerve injury along the jawline.
  • Ask how many sessions and how much downtime each option involves.
  • Request side-profile before-and-after photos.

Frequently asked questions

What is the best treatment for a double chin?

It depends on the cause. Small fat pockets respond to injections or fat freezing, larger fat to liposuction, loose skin to tightening or a neck lift, and a weak chin to chin augmentation. A doctor's assessment guides the choice.

How many injection sessions are needed for a double chin?

Deoxycholic acid treatments often need 2–4 sessions, sometimes more, spaced about 4–8 weeks apart. The number depends on fat volume and response.

How long does swelling last after double chin injections?

Swelling is common and can be noticeable for several days, sometimes up to about two weeks. Numbness and firmness may last a little longer before settling.

Is chin liposuction better than injections?

Liposuction removes more fat in one procedure with predictable results, but involves a small incision and more downtime. Injections avoid surgery but need multiple sessions and suit smaller pockets.

Can losing weight get rid of a double chin?

Weight loss often reduces a double chin, but some people keep submental fullness due to genetics, chin shape or skin laxity. Targeted treatments can help when weight loss alone does not.
