What's NOT in the Quoted Price

When I asked five Gangnam clinics for a Thermage FLX quote in February 2026, the headline numbers ranged from 1.4M to 2.1M KRW. After I drilled into what was actually included, the effective price range narrowed to 1.7M to 2.3M. The headline number is rarely the final number. This page is the cheat sheet I now share with every Taipei friend who DMs me asking 'why is this clinic so cheap?' The answer, almost always, is that something is not in the quote. Below are the eight categories of line items that get added later, plus the exact phrasing to use when you ask the clinic to commit to a total-out-the-door price in writing.

Korean aesthetic clinics quote in Korean won (KRW), and the headline number you see in a Naver ad or a Google search typically refers to a single line item: the Thermage FLX procedure with a Total Tip 4.0 cartridge at a baseline pulse count. Everything else, from numbing cream to the post-care kit you walk out with, may or may not be in the bundle. The Ministry of Health and Welfare (MOHW) requires itemized receipts but does NOT regulate which items must be bundled into the headline price. That gap is where the price spread lives. Your job is to close the gap with one question, asked in writing: 'Please confirm the total out-the-door price including all line items below, with no further charges on the day.'

The Total Tip 4.0 cartridge is the standard for full-face Thermage FLX. But pulse count within that cartridge varies. A baseline package may include 600 pulses, while the same clinic's premium tier delivers 900 pulses. The price difference is often 30 to 50%. Some clinics also sell 'half-face' packages at 300 to 400 pulses. None of these are scams, but they are different products. Ask: 'Which cartridge will be used, and what is the committed pulse count?' Get both in writing before deposit.

Topical numbing cream applied for 30 to 45 minutes before treatment is the default. Most Gangnam clinics include this in the headline price, but a minority charge 50,000 to 100,000 KRW separately. Oral analgesics (typically acetaminophen + tramadol) are sometimes free, sometimes 20,000 to 40,000 KRW. Nitrous oxide laughing gas, offered at a small subset of clinics, runs 100,000 to 200,000 KRW extra. None of these change the clinical outcome. All of them change the invoice.

Many clinics send you home with a post-care kit: cooling mask, anti-inflammatory cream, hyaluronic acid serum sample. Sometimes this is included as a courtesy. Sometimes it appears as a 80,000 to 150,000 KRW line item on the receipt. Sometimes you are upsold to a 'premium recovery package' for 300,000+ KRW on the day. Ask in advance whether post-care is bundled, sold separately, or optional.

Thermage FLX results unfold over 2 to 6 months. Most reputable clinics offer at least one complimentary in-person check-up at 4 to 12 weeks. Some clinics charge a 'follow-up consultation fee' of 30,000 to 80,000 KRW, particularly for international patients who fly back specifically for the visit. Online follow-ups via LINE, WhatsApp, or WeChat are typically free, but ask. The cost of an unplanned re-visit, including flights and hotel, is your problem, not the clinic's.

Clinical-grade before/after photography (typically VISIA or Antera 3D imaging) is standard at premium clinics and bundled into the price. At mid-tier clinics, it may be a 50,000 to 100,000 KRW add-on. At budget clinics, it may not be offered at all, which makes it difficult to objectively evaluate your results at 3 and 6 months. If documented before/after matters to you (it should, because results are gradual), confirm photography is included BEFORE you book.

Korean clinics generally absorb credit card processing fees on domestic Korean cards but may add 2 to 4% on international Visa, Mastercard, or Amex. VAT (10%) is usually included in the displayed price, but on rare occasion it is added after. Dynamic currency conversion (DCC) at the point of sale can quietly add another 3 to 5%. Ask: 'Is the price you quoted me VAT-inclusive, and is there a surcharge for international cards?' Pay in KRW, not your home currency, when prompted at the terminal.

A small number of Gangnam clinics charge a 'coordinator fee' or 'translation fee' of 50,000 to 100,000 KRW for international patients. The majority do not, because the coordinator service is a competitive differentiator. If a coordinator fee appears on your quote, ask why, and compare against two other clinics. This single line item is one of the easiest to negotiate away.

The single largest source of unexpected charges is consultation-day upsells: an add-on Shurink Universe session, an Ulthera SPT bundle, a 'premium' Thermage cartridge upgrade, a series of LDM ultrasound recovery sessions. Some of these are genuinely useful. None of them belong on a Thermage FLX-only quote. If a coordinator pitches you a bundle during the in-person consultation that doubles the price, take the printed quote, leave the chair, walk to a nearby cafe, and read this page again. Make the decision with caffeine, not with a numbing cream timer running.

Send this exact message to the clinic in writing: 'Please confirm in writing the total out-the-door price for Thermage FLX with [cartridge model], [pulse count], including: numbing cream, oral painkillers, post-care kit, all consumables, photography, VAT, and any coordinator or international card surcharges. I will not pay any additional charges on the day. Please reply with the final number.' If the clinic refuses to commit, that refusal is your answer. Move to the next clinic on your shortlist.

As of Q1 2026, a fair all-in Gangnam price for a full-face Thermage FLX with 900-pulse Total Tip 4.0, numbing cream, post-care kit, and photography is roughly 1.6M to 2.4M KRW. Below 1.4M, something is missing or downsized. Above 2.6M, you are paying a premium for clinic branding or location. The KHIDI international patient portal and the MFDS device registration data are both public and free to cross-check. Use them.

For Taipei and Hong Kong readers, the KRW/TWD and KRW/HKD pairs swing 3 to 5% in any given quarter. A 2M KRW treatment can cost TWD 47,000 one month and TWD 49,500 the next without the underlying price changing. Lock the KRW number in writing, then convert at booking. Do not let the clinic quote you in TWD or HKD, because that conversion is rarely in your favor.

“A headline price is a marketing claim. An out-the-door price, in writing, is a contract.”

Frequently asked questions

Is the Thermage FLX headline price always VAT-inclusive in Korea?

Usually yes, but confirm in writing. Korean aesthetic clinics typically display VAT-inclusive prices, but exceptions exist. Ask 'Is this price VAT-inclusive?' explicitly before deposit.

How much should numbing cream and oral painkillers cost?

Topical numbing cream is typically included. Oral analgesics, if charged separately, range 20,000 to 40,000 KRW. If a clinic charges 100,000+ KRW for basic numbing, push back or compare to two other quotes.

What is a fair price for the post-care kit?

A standard post-care kit (cooling mask, anti-inflammatory cream, sample serum) is worth roughly 50,000 to 100,000 KRW retail. If a clinic adds it as a 150,000+ KRW line item, the markup is high. Either accept it or ask for it to be bundled.

Do I need to pay for follow-up appointments?

Most international-friendly Gangnam clinics include one complimentary in-person follow-up at 4 to 12 weeks. Online follow-up via LINE or WeChat is typically free. Unplanned re-visits requiring a return flight are your cost, not the clinic's.

Should I pay in KRW or my home currency at the credit card terminal?

Always pay in KRW. Dynamic currency conversion (DCC) at the point of sale typically adds 3 to 5% versus your card issuer's rate. Decline DCC when the terminal prompts you.

Is a 'coordinator fee' for international patients normal?

Not at most reputable Gangnam clinics. Coordinator service is usually a competitive differentiator bundled into the headline price. If a 50,000 to 100,000 KRW coordinator fee appears, negotiate it away or compare to two other clinics.

What's the most common on-the-day upsell I should expect?

Add-on RF or HIFU sessions (Shurink Universe, Ulthera SPT), premium cartridge upgrades, or recovery series packages. Some are useful, none belong on a Thermage-FLX-only quote. Make the decision off-site, not in the chair.

What is a fair all-in Gangnam Thermage FLX price as of 2026?

For a full-face Thermage FLX with 900-pulse Total Tip 4.0, including numbing, post-care, and photography, fair all-in is roughly 1.6M to 2.4M KRW. Below 1.4M something is downsized. Above 2.6M you are paying a branding premium.
