How We Choose Seoul Aesthetic Clinics: 6 Criteria

We choose Seoul aesthetic clinics by checking six things on official pages: registration, doctor credentials, consultation language, posted prices, location and hours, and device information. This page explains each check so you can repeat it yourself.

We choose Seoul aesthetic clinics with six criteria: foreign-patient registration, doctor credentials, a stated consultation language, clearly posted prices, location and hours, and device information. Each one is checked against the clinic's own official pages and public databases, never against ads or search summaries.

Seoul has 4,620 registered foreign-patient institutions (Korea Health Industry Development Institute, Medical Korea, 2026-11-10). That is too many to compare by eye. Our fact table covers 38 Seoul clinics, checked on official websites and Medical Korea on 2026-11-09 and 2026-11-10. This page explains the method only, so you can run the same checks on any clinic, including for Ulthera (Ultherapy) and Rejuran.

What are the 6 criteria?

#	Criterion	What we look for	Where to verify
1	Registration	The clinic appears in the foreign-patient institution register	Medical Korea
2	Doctors	Number of doctors, and a named specialty (not just the word "specialist")	Clinic website, HIRA
3	Language	A consultation language written out, such as English or Chinese, not only a chat button	Clinic website, then confirm when booking
4	Prices	A regular price list with unit (shots or cc), VAT status and update date	Clinic website, HIRA non-covered fee data
5	Location and hours	Official address, station exit, walking time, closed days and lunch break	Clinic website
6	Device and procedure	Device model named, such as Ulthera Prime, not only a generic ultrasound label	Clinic website, MFDS lookup

When we list clinics in other guides, the order follows how many of these six are met. A clinic that leaves a box empty is shown as "not posted" instead of being filled in with a guess.

Does registration mean a clinic is good?

No. Registration is a legal step, not a quality score. A medical institution that wants to attract foreign patients registers under Article 27-2 of the Medical Service Act. The system does not evaluate treatment quality or results. We use it only as a minimum check that the clinic is on the official register.

Public bodies each cover a different task. Use the right one for the right question:

Medical Korea (medicalkorea.or.kr): look up foreign-patient institution registration.
HIRA, the Health Insurance Review and Assessment Service (hira.or.kr): hospital and doctor numbers, and non-covered fee information.
MFDS medical device e-service (emedi.mfds.go.kr): look up approval information for medical devices.
Korea Medical Dispute Mediation and Arbitration Agency (k-medi.or.kr): consultation, mediation and arbitration for medical accidents.
Taiwan Bureau of Consular Affairs (boca.gov.tw): consular help for emergencies while travelling abroad.

How do we read a clinic's price list?

Price pages are the least consistent part of clinic websites, so we apply fixed rules:

Event or promotion prices are not treated as regular prices. If a page marks a price as an event, or shows a crossed-out original beside a sale figure, we leave it out.
A range (lowest to highest) is shown as a range and labelled as one. It is not an average.
Every price needs a unit. "100 shots" or "2cc" is comparable. A bare "from" price is not.
VAT is recorded as included, excluded or not stated. Cosmetic non-covered care in Korea is subject to 10% VAT, but each clinic's list marks it differently.
The posting date matters. Old tables are flagged because current prices may differ.

Which names should you search for from Taiwan?

Clinics often use Korean product names, while Taiwanese searches use different words. Matching them avoids comparing the wrong things.

Ulthera (Ultherapy) is called 美國音波, 音波拉提 or 超聲刀 in Taiwan.
Ulthera Prime is the model name to look for. It uses real-time ultrasound imaging to check depth, with 1.5, 3.0 and 4.5 mm depths.
海芙音波 and HIFU are general terms for high-intensity focused ultrasound devices. They are not one brand.
슈링크, 리니어지 and 브이로 are Korean-made HIFU devices. They are different products from Ulthera.
Rejuran is called 麗珠蘭 or 鮭魚針 in Taiwan.

Is a registered clinic safer than an unregistered one?

Registration only shows that the clinic is on the foreign-patient institution register. It is not an assessment of care or results, so use it together with the other five checks.

Should I pick the clinic with the lowest posted price?

Not on price alone. Lists differ in unit (shots or cc), VAT status and update date. Compare only like with like, and ask the clinic to confirm the total in writing.

Where can I get help if something goes wrong?

For medical accidents, the Korea Medical Dispute Mediation and Arbitration Agency offers consultation, mediation and arbitration. For emergencies while travelling, the Taiwan Bureau of Consular Affairs gives consular assistance.

These criteria help you narrow a list, not decide a treatment. Whether a procedure suits you is for the clinic to say: 醫師諮詢後判斷 / a doctor decides after consultation.

General information from public sources, not medical advice. A doctor decides suitability after consultation. Check prices and details with each clinic.
