Booking and consultation: how far ahead, and what to send

How far in advance should I book a Seoul dermatology clinic?

There is no official lead time, so plan backwards from what you need. A consultation slot is short and easy to move. A particular doctor, a long lifting session on one device, or a weekend appointment is harder to find. You also need time for two or three rounds of messages, because a clinic may have follow-up questions once it sees your photos. Check whether the clinic opens over Korean public holidays such as Seollal and Chuseok if your trip falls near them.

Timing matters for results too. In a phase 3 trial of a Korean-made botulinum toxin for frown lines, improvement showed from day 2 and the median time to onset was 3 days^[1]. Booked on your last afternoon, you would fly home before seeing whether it worked. The downtime planner gives the same kind of timing for other treatments.

What should I send before my visit?

• Your dates in Seoul and the time of your flight home.
• What you want to change, in one or two sentences, and what you want to avoid.
• Photos in daylight without filters or makeup: front, left and right.
• Past treatments with dates and, for injectables, the product name and amount.
• Medicines and supplements, including isotretinoin, blood thinners and hormone treatment.
• Allergies, pregnancy or breastfeeding, a history of cold sores or raised scars.
• The language you want to use, and whether you will bring your own interpreter.

Photos help a clinic prepare, but they do not replace the examination. Expect the doctor to change or refine the plan once you are in the room.

How does interpreting work at Korean clinics?

Language support varies from clinic to clinic, so ask what is available on your date and in which language. The law sets a minimum for clinics registered for foreign patients: patient rights posted in a foreign language, and the diagnosis, treatment method and possible side effects explained separately (foreign patient Act, Article 8, checked 2026-10-18). The same Act lets the Ministry of Health and Welfare train medical interpreters and run a medical interpreting proficiency test (Article 13, checked 2026-10-18).

Who interprets makes a measurable difference. In recorded emergency department visits in the United States, 12% of errors by professional interpreters could have had clinical consequences, against 22% for ad hoc interpreters such as relatives or untrained staff; interpreters with at least 100 hours of training made far fewer such errors^[2]. A systematic review reached the same direction: professional interpreters were linked with better communication, care and satisfaction than ad hoc ones^[3]. A friend is fine for directions and small talk. For the consent discussion, ask for it in a language you understand, with a trained interpreter if needed, and a translated form to review.

For everyday help outside the clinic, the 1330 Korea Travel Helpline offers tourist interpretation by phone and chat: dial 1330 inside Korea or +82-2-1330 from abroad (VisitKorea, checked 2026-10-18). It is a travel service, so use it for taxis and pharmacies rather than for medical consent.

Should I book through an agency or directly?

Both are legal, and both are regulated. Agencies that bring foreign patients to Korean clinics must register with the city or provincial government, carry guarantee insurance, hold a minimum capital and keep an office in Korea (foreign patient Act, Article 6, checked 2026-10-18). Commissions above the rate set by the Ministry and false information are banned (Article 9, checked 2026-10-18). Medical Korea listed 2,888 registered facilitators when checked (Registered Facilitators, checked 2026-10-18). Booking directly with the clinic means one fewer party between you and the doctor; an agency can help with transport, hotels and interpreting.
