Being seen in English

No interpreter, no agency

This is a single-doctor clinic, so the person who examines you is the person who talks to you. The consultation is held in English with the doctor directly, with no interpreter and no medical-tourism agency in between. That matters most when the conversation turns to side effects, because nothing has to be relayed through a third person before it reaches the doctor.

The paperwork is short. Registration takes a passport; Korean national health insurance, a residence card, and a visa document are all unnecessary. Weight management is not covered by Korean insurance for anyone, so residents and visitors are quoted the same private rate from the same published list.

What is handled in English

  • Consultation with the doctor, without an interpreter
  • Medical history and current medication review
  • Dosing schedule and injection technique
  • Written side-effect guidance and what warrants contact
  • Prescription summary for airport screening
  • Itemised receipt for insurance or tax purposes
  • Follow-up messages after you fly home

What is treated here

No interpreter fee and no international-patient surcharge. Neither is charged, because neither is involved. Dr. Su Jung Yoon sees you at the first consultation and at every follow-up.

Why not Gangnam

Most English-language material about Korean clinics points to Gangnam, and for cosmetic dermatology that reflects where the density actually is. Weight management is a different service. It needs a consultation, a scale, a blood draw, and a follow-up, not a showroom.

This clinic is in Dongjak-gu, one district west. It is fifteen minutes from Gangnam Station on the subway. The rent difference is one of the reasons the published price list is what it is.

Frequently asked

Where exactly is the clinic?

4F, Hana Bank Building, 109 Dongjak-daero, Dongjak-gu, Seoul. Isu Station Exit 12, about two minutes on foot. Isu is on Line 4 and Line 7.

Is it in Gangnam?

No. It is in Dongjak-gu, one district west, about fifteen minutes from Gangnam by subway. Rents are lower here, which is part of why the price list looks the way it does.

How do I get there from Incheon Airport?

AREX to Seoul Station, then Line 4 south to Isu. Roughly ninety minutes door to door.

Do you see patients on weekends?

Saturday 10:00 to 15:00, with no lunch break. Closed Wednesday and Sunday. Open on public holidays.

How far ahead should I book?

Same-week appointments are usually available. A week ahead gives the widest choice, particularly for Friday evenings and Saturdays.

Does the doctor speak English, or is there an interpreter?

The consultation is in English with the doctor who examines you. Nothing is relayed through a third person, so you can describe symptoms and ask about side effects in your own words. No interpreter fee is charged, because no interpreter is involved.

Do I need Korean insurance, a residence card, or a Korean phone number?

No. Registration takes a passport. Korean national health insurance is not required, and neither is a residence card or a visa document. Weight-management treatment is not covered by Korean insurance in any case, so residents and visitors pay the same private rate.

Do foreigners pay more here than Korean patients?

No. The published price list is the domestic one. No agency commission and no international-patient surcharge is added. Prices for GLP-1 prescriptions are listed dose by dose on this site rather than quoted on enquiry.

What do I leave with after the visit?

Where a prescription is appropriate, medication is dispensed the same day, with the dosing schedule and injection technique explained in English. You also receive an English prescription summary for airport screening and an itemised receipt.
