Read the quote line by line
A useful quote names each treatment, the device or product, the quantity (for example shots, cc or areas) and whether consultation fees and numbing cream are included. If you are given one total, ask for it to be broken down.
VAT: included or added?
Cosmetic treatments in Korea are generally subject to value added tax. Some price lists show amounts before VAT and add it at the counter; others show the final amount. Ask which one you are reading, so the bill does not surprise you.
Tax refund questions
Korea has at times offered foreign visitors a VAT refund on some cosmetic procedures at registered clinics. Schemes like this can change, so treat any information you read online as a starting point.
Before you pay, ask the clinic whether a refund applies to your treatment on your dates, what document they issue, whether your passport is needed at checkout, and where the refund is processed.
Cards, cash and currency
Ask which payment methods the clinic accepts. If the card terminal offers to charge you in your home currency, the conversion is usually done at the terminal's rate; paying in Korean won lets your own bank convert it. Your bank may also add a foreign transaction fee.
Deposits, packages and refunds
A deposit to hold a booking, or a package of sessions paid up front, may lower the per-visit figure but ties you to the clinic. Ask in writing what happens if you cancel, change dates or stop after the first session.
Keep the paperwork
Ask for an itemised receipt. It helps if a doctor at home needs to know what was done, and for any insurance, refund or card dispute later.
