Short answer

Plastic Surgery(성형외과) is generally the first department to see for a double chin, as surgeons there assess both structural and cosmetic factors contributing to the appearance. If the double chin is suspected to be related to hormonal imbalance, thyroid issues, or significant weight gain, a referral to Internal Medicine(내과) or Endocrinology(내분비내과) may follow after initial evaluation.

Which department

  1. 1Plastic Surgery (성형외과)
    Plastic surgeons are generally trained to evaluate the anatomical factors behind a double chin, including fat distribution, skin laxity, and muscle structure around the jaw and neck area. They can assess whether the cause is primarily cosmetic or structural and discuss what further consultation may be needed. — First / second line: In most cases, visiting a plastic surgery clinic (의원) as a first step is common when the concern is primarily cosmetic or appearance-related. If more complex evaluation is needed, the clinic may refer you to a larger hospital (병원) for additional workup.
  2. 2Internal Medicine / Endocrinology (내과 / 내분비내과)
    When a double chin develops alongside unexplained weight gain, fatigue, or swelling in the neck, it may be related to thyroid dysfunction, hormonal conditions, or metabolic factors — areas managed by internists or endocrinologists. A physician in this department can assess whether an underlying medical condition is contributing to the appearance. — First / second line: This department is generally considered when a double chin appears alongside systemic symptoms rather than as a standalone cosmetic concern. A referral letter (진료의뢰서) from a primary care clinic may be advisable when visiting a secondary or tertiary hospital for this evaluation.
  3. 3Dermatology (피부과)
    Dermatologists may be consulted when skin laxity or texture changes in the chin and neck area are the main concern, as skin conditions can sometimes contribute to the overall appearance of a double chin. They evaluate skin quality as a separate dimension from fat or muscle structure. — First / second line: A dermatology clinic (의원) can be a first point of contact if the concern is specifically about skin elasticity or texture in the neck and chin area, rather than fat or skeletal structure. Depending on findings, coordination with plastic surgery may be suggested.

Go to the ER / call 119 if

If any of the following applies, do not choose a department — go to an emergency room or call 119 (Korea's emergency number).

  • Sudden, rapidly growing swelling or lump in the neck or under the chin that was not present before.
  • Difficulty swallowing or breathing that develops alongside neck or chin swelling.
  • Severe pain in the neck, chin, or jaw area that appears suddenly and worsens quickly.
  • Fever combined with a hard, tender swelling under the chin or along the jaw.
  • Numbness, weakness, or drooping on one side of the face appearing together with neck swelling.

Before your visit

  • Note approximately when you first noticed the double chin and whether it appeared gradually or suddenly.
  • Record any accompanying symptoms such as fatigue, unexplained weight changes, neck swelling, or difficulty swallowing.
  • Prepare a list of any medications or supplements you are currently taking, as some can affect weight distribution or fluid retention.
  • Bring results of any previous blood tests, thyroid ultrasounds, or imaging studies if you have had them done.
  • Think about your family history of thyroid disease, metabolic conditions, or similar physical traits, as this information can be helpful during consultation.
  • Be ready to describe your general lifestyle, including recent weight changes, diet habits, and sleep patterns, as these may be relevant to the doctor's assessment.

General principles

A double chin can arise from a variety of factors, including subcutaneous fat accumulation, skin laxity, muscle tone changes, skeletal structure, or — less commonly — an underlying medical condition such as thyroid dysfunction or fluid retention. Because the cause can differ significantly between individuals, the appropriate clinical department depends on which factor is most likely responsible, which is why a medical consultation rather than self-assessment is generally recommended.

In the Korean healthcare system, the general flow for a cosmetic or appearance-related concern like a double chin typically begins at a primary care clinic (의원), where the practitioner can evaluate whether the concern is primarily aesthetic or whether further investigation is needed. If an underlying systemic cause is suspected, the clinic may issue a referral letter (진료의뢰서) directing the patient to a secondary or tertiary hospital for specialist evaluation.

Diagnostic approaches in this area generally involve a physical examination to assess fat distribution, skin elasticity, and neck anatomy, and may include imaging or blood tests if a medical cause is suspected. The scope and type of evaluation are determined by the clinician based on individual presentation, and any decisions about further steps are made in consultation with the doctor.

FAQ

Should I go to a local clinic (의원) or a larger hospital (병원) first for a double chin?

In most cases, starting at a local plastic surgery or internal medicine clinic is a practical first step, as the doctor there can assess your situation and determine whether moving to a larger facility is necessary. Note that a referral letter (요양급여의뢰서) is legally required for normal insurance coverage only at tertiary hospitals (상급종합병원); secondary hospitals (병원/종합병원) can generally be visited directly without a referral and without any extra cost under the general health insurance (건강보험) structure.

How do I know if my double chin is a cosmetic issue or a medical one?

Generally, a double chin that has been present for a long time without other symptoms is more likely to be structural or cosmetic in nature, while one that appeared suddenly or is accompanied by fatigue, neck swelling, or weight changes may warrant medical evaluation. A physician can help distinguish between these possibilities during consultation, so it is advisable not to self-diagnose.

Will my Korean health insurance (건강보험) cover treatment for a double chin?

In Korea, procedures or treatments that are considered purely cosmetic are generally not covered by the national health insurance system. However, if the consultation reveals an underlying medical condition, the diagnostic workup and treatment for that condition may be covered — the specifics depend on the clinical findings and the treating physician's documentation.

Is the approach different for older adults or children with a double chin?

For older adults, skin laxity and age-related fat redistribution are more commonly discussed factors, and the evaluation may also include a broader health assessment depending on overall condition. For children or adolescents, a double chin is less commonly a standalone cosmetic concern and is more often evaluated in the context of overall growth and weight — in such cases, a pediatrician (소아청소년과) may be the appropriate first contact before any specialist referral.
