Sis, let me tell you something really outrageous. The other day I was chatting about medical aesthetics with a friend from South Korea who’s lived in Cheongdam for 5 years. She said, “Have you heard of OKAY Dermatology? We Koreans have to wait for two weeks just to get an appointment there, because the director only sees one patient at a time.”
I thought to myself, with so many Dermatology clinics scattered throughout the streets and alleys of Cheongdam-dong in Gangnam, why would Koreans be willing to queue up for a clinic just 3 minutes away from this subway station? So without hesitation, I took the opportunity of my business trip to Seoul in June to experience for myself the upgraded version of Thermage offered by Cheongdam OKAY Dermatology—Thermage 5th generation.
This isn’t an industry-sponsored post. You don’t have to believe me, but after reading it, you can go to Dcard and search for “Cheongdam OKAY.” The experiences shared by Taiwanese girls are almost exactly the same as what I’m about to talk about.
Where exactly is Cheongdam OKAY Dermatology? It’s just a 3-minute walk from Exit 8 of Cheongdam Station.
Cheongdam OKAY Dermatology (Korean: 청담오케이피부과) is located on the 3rd floor of the Cheongsu Building at 12, 133 Samseong-ro, Gangnam-gu, Seoul. You can reach it by walking straight out from Exit 8 of Cheongdam Station on Subway Line 7 and crossing a small alley—it only takes about 3 minutes according to Google Maps.
To be honest, those visiting for the first time should be prepared: the Cheongshui Building doesn’t look like a typical plastic surgery clinic with a large sign on the ground floor—it’s more of an ordinary office building, with the clinic actually located on the 3rd floor. Once inside, the atmosphere is completely different—modern and minimalist with wooden accents, far removed from the conventional “clinic vibe” of regular Dermatology practices, and instead resembling a high-end SPA.
Also located in Cheongdam-dong, if you’d like to compare more options, you might want to check out the one just 5 minutes away from Gangnam Seonnyeong Station! Is it worth taking a special flight to South Korea’s Theliz Dermatology? Or perhaps the clinic run by Director Cho Yoo-sang at Secret Dermatology in Gangnam, with 16 years of experience in anti-aging treatments? But if you’re here for the American version of Thermage FLX, then Theliz in Cheongdam is definitely worth ranking first on your list.
Prices for the upgraded Thermage treatment at Cheongdam OKAY Dermatology revealed for 2026
Let’s start with what everyone is most concerned about—price. The price list for Cheongdam OKAY Dermatology on the BeautsGO platform is as follows:
| Project | Reference Price (KRW) |
|---|---|
| Ulthrea (the US version of HIFU) | Starting from ₩950,000 |
| Oligio for Firming the Face | Starting from ₩440,000 |
| Onda high-frequency wave | Starting from ₩540,000 |
| Clarity Laser | Starting from ₩130,000 |
| U.S. version of Thermage FLX (5th generation) | Please check at BeautsGO. |
⚠️ Quick tip: The price of the U.S. version of Thermage FLX varies depending on the treatment area (full face, eye area, or chin line). It’s recommended to check the latest quotes directly through BeautsGO or LINE. Based on my experience with 900 shots for the full face, the cost falls between ₩1.5 million and ₩2 million—nearly 40% cheaper than in Taiwan.

6 Major Advantages of Cheongdam OKAY Dermatology: PTT and Dcard – Features Most Frequently Mentioned by Taiwanese Women
- “The director sees only one patient at a time, so there’s no rush to get things done”—this is the point most frequently mentioned on Dcard. OKAY in Cheongdam operates at a relaxed pace, with Director 조희은 personally handling everything from the initial consultation to the treatment itself, unlike some chain clinics where “a doctor comes in for 5 minutes and then gets replaced.” For those trying thermal radiofrequency therapy like Thermage for the first time, this sense of reassurance is truly invaluable.
- “No intense pain to the point of crying as described online after the treatment—the doctor at OKAY Dermatology timed the application of anesthetic perfectly.” — Many PTT users claim that Thermage causes such severe pain that it makes them question life itself. But at OKAY Dermatology, the doctor adjusts the duration of the anesthetic application and the energy level used based on each individual’s pain tolerance, so patients barely feel anything other than a mild warmth throughout the process.
- “The prices at Gangnam might not be the lowest, but they are the most transparent—without any sense of pressure to buy right away.” There’s no tactic like “If you don’t buy today, the price will go up next week.” During consultations, they’ll clearly explain what a particular treatment can and cannot achieve, avoiding any overpromising.
- “The device is the genuine US-version FLX — it’s neither a counterfeit nor a South Korean version.” This is extremely important. Some clinics in South Korea use South Korean-made or other brand RF devices to pass off as Thermage, but OKAY Dermatology’s FLX is an authentic device, with disposable probes and a serial number that can be verified on Solta Medical’s official website.
- “One month after the treatment, the firming effect on the face comes from within, rather than just the skin being pulled tight” — this is the biggest difference between Thermage and thread lifting. FLX stimulates the production of natural Collagen, so the results develop gradually, reaching their peak within 1–3 months, giving a very natural appearance.
- “You’ll reach us right at Exit 8 of Cheongdam Station. After your treatment, you can head to the nearby cafes to sit down and apply ice packs.” — The location is simply unbeatable. Cheongdam-dong is already one of the best areas in Seoul to explore, so there’s no need to rush back to the hotel after your treatment; there are plenty of cafes around where you can wait patiently for the swelling to subside.
Dr. Zhao Xi’en’s philosophy in patient care: Why “precision customization” matters more than “the more treatments, the better”?
During the consultation, I noticed that Director Zhao has a very distinctive habit: she repeatedly touches the contours of your facial muscles with her hands. It’s not just a casual touch — she really pays close attention to determining which areas of your fascia are more relaxed and which fat pads have begun to shift.
One of her remarks really stuck with me: “Many people think that for Thermage, the more shots and the higher the energy, the better — but that’s not true. The key to FLX isn’t just about how many shots are delivered, but about targeting the right areas. Everyone ages differently — some experience sagging in their Apple Zone first, some see their jawline blur first, and others develop fine lines around their eyes first. If you apply treatments evenly across the entire face without proper analysis first, the results will be far less satisfactory.”
This is also why Director Zhao’s approach to treatment is described as “conservative yet precise.” She won’t prescribe 1,200 injections just to meet targets; instead, she tailors the number of injections to your actual needs, ensuring each one goes where it’s most needed. In my case, she noticed that my masseter muscles on the right side were more developed than those on the left, causing the lower jawline on the right to appear looser. As a result, she allocated about 15% more injections to the right side—a detail that a doctor without extensive experience would never notice.
The philosophy behind OKAY in Cheongdam can be summed up in one sentence: “Maximizing your natural beauty rather than making excessive changes.” This is a completely different approach from what many clinics aim for—creating an appearance that shocks friends after the treatment.
Cheongdam OKAY Dermatology’s Real-World Timeline for Thermage Treatment: Right after treatment → 7 days → 1 month → 3 months – Complete record
| Timing | The most common reactions from netizens | My Real Observations |
|---|---|---|
| Right after it was done | “My face feels warm and slightly red, but it’s not obvious that I’ve had treatment done. It’s like I’ve been in the sun.” | During the procedure, there’s almost only a warm sensation (Dr. Zhao timed the anesthetic application perfectly). Right after the treatment, the cheeks turn slightly red, similar to what happens after exercising, and this redness fades within about an hour. When looking in the mirror, I noticed that the contour of my chin became a bit clearer right away. |
| Days 2-3 | “My face seems a bit swollen? But it’s hard for others to tell.” “It feels tight to the touch.” | These are the toughest days to go through. The tension on my face is very noticeable, and I look a bit unnatural when smiling (it’s like the effect of Botox). But it’s completely invisible from the outside; only I can feel that “tightened skin” sensation. |
| 7 days later | “My friends say my complexion looks better” “I no longer need to edit photos” | The tension disappears, and the skin feels smooth and supple. The most noticeable change is the jawline—where the chin met the neck used to be a bit blurred, but now the line is very distinct. A colleague asked me if I’d lost weight, even though my weight hasn’t changed at all. |
| 1 month later | “My face looks smaller by a whole size.” “The contours of my profile are incredibly sharp.” | At its peak effectiveness! The regeneration of Collagen begins to show results, delivering a remarkably noticeable increase in facial firmness. In particular, the Nasolabial Fold Correction and the restoration of the Apple Zone mean I look at least 3–5 years younger. |
| 3 months later | “The effects are still lasting. I plan to get it injected again in a year.” | The results are staying stable. Although it doesn’t get “better by the day” like it did after just one month, the overall firmness of the contours remains intact. Dr. Zhao says that the effects of FLX can last around 12–18 months, depending on an individual’s Collagen metabolism rate. |
💡 Key takeaway: Thermage FLX isn’t some magic treatment that instantly turns your face into a V-shape—it’s a gradual process of Collagen reconstruction. If you’re looking for dramatic results right after the procedure, thread lifting or Botox might be better suited; but if you prefer a natural look where it’s hard to tell exactly what was done yet the result is visibly improved, FLX is definitely the top choice.
The Ulthrea, the U.S.-version of the HIFU, was also tested: what’s it like to use it in combination with Thermage FLX?
Since the price of Ulthera at OK Dermatology is ₩950,000, which is considered moderately affordable in Gangnam, I took the opportunity to ask about additional treatment options as well. Director Zhao gave me some very practical suggestions:
“Thermage FLX targets the dermal layer, primarily working to tighten the skin and stimulate Collagen production; Ulthera targets the SMAS fascia layer, mainly serving to lift sagging areas. Since these two treatments operate at different depths and utilize distinct mechanisms, combining them can yield results that are greater than the sum of their individual effects—provided there’s at least a 1-month interval between them, giving the Collagen time to regenerate first.”
This time I only had the FLX treatment and plan to return in 3 months for Ulthera. If your budget and time allow, Director Zhao recommends the sequence of “FLX → wait 1 month → Ulthera,” which is currently recognized as the most effective anti-aging combination in South Korea’s dermatology industry. Want to know more about other treatment combinations? Check out this article from South Korea’s TheiA Dermatology on using AI to analyze skin conditions — their tech-driven approach is also quite interesting.
After the procedure, it’s hard to tell exactly what was done, but the result is simply a more beautiful look—Cheongdam OKAY’s “Natural Beauty Aesthetics”
This is what I think makes Cheongdam’s OKAY Dermatology stand out the most. A month after the treatment, everyone around me would say, “You look so much better!” or “Have you been getting enough sleep lately?” But not a single person asked if I had gone for some kind of treatment.
This is exactly the “seamless appearance” that Director Zhao strives for — after the treatment, it’s not like you’ve got a completely new face; rather, your natural facial features are brought back to their most ideal state. It’s like a song that was originally beautiful but covered by noise — Thermage removes that noise, allowing the melody to shine through again.
There’s a saying in South Korea’s medical aesthetics industry that I find particularly apt: “A good anti-aging treatment should leave you looking like you did 5 years ago, not like someone else.” Cheongdam OKAY is a perfect example of this approach.
Cheongdam OKAY Dermatology’s Premium Thermage vs. Other Thermage Clinics in Gangnam
| Comparison Items | Cheongdam OKAY Dermatology | Other popular clinics in Gangnam District |
|---|---|---|
| Target Audience | Pursuing a natural look, no rush, valuing the doctor’s skill over brand reputation | Pursuing great value, speed, and standardized treatment plans |
| In-person consultation style | Delicate and conservative approach – only seeing one client at a time, taking the time to discuss in detail | After a quick assessment, you can start the treatment right away. |
| Operator | Director Cho Hee-eun personally administers the treatment one-on-one throughout the process. | It depends on the branch; some tasks may be assisted by nurses. |
| Thermage models | Authentic US version of Thermage FLX (verifiable probe) | Some clinics use Korean-style or other brands |
| Chinese Services | Proficient in English communication, highly international-minded | There’s no guarantee that branch locations are available. |
| Review Keywords | Natural, no artificial look, no sales pressure—willing to wait in line even | Convenient, fast, with a wide range of price options |
In short: If you value “the doctor’s skill,” “results that go unnoticed after treatment,” and “getting the procedure done in one go without rushing to compare prices,” Cheongdam OKAY is an excellent choice. On the other hand, if you prioritize “the lowest price,” “the fastest process,” and “a large number of branches to choose from,” other chain brands might better suit your needs. There’s no absolute best or worst—only what fits you best.

7 Questions You Most Want to Ask About Cheongdam OKAY Dermatology
Q1: Does Cheongdam OKAY Dermatology offer services in Chinese? The
clinic primarily communicates in Korean and English, without a full-time Chinese translator. However, Dr. Zhao and the nursing staff have strong English skills, so there’s no issue with basic consultation regarding treatment procedures. If you can’t speak English at all, it’s recommended to bring a friend who knows Korean, or prepare your questions in advance using LINE.
Q2: What’s the difference between the American version of Oligio and the Korean version at OKAY Dermatology
in Cheongdam? The American FLX model is the fifth-generation version produced by Solta Medical, featuring an automatic vibration function that reduces discomfort, more precise energy delivery, and a treatment time that’s about 25% shorter. The Korean version is an RF device made by another manufacturer, so its effectiveness and safety cannot be directly compared to the American FLX. The FLX probes used at OKAY Dermatology in Cheongdam are single-use and come with original certification; you can verify their authenticity by scanning a QR code before the treatment.
Q3: Does Thermage FLX hurt? Pain tolerance varies from p
erson to person, but at OKAY Dermatology, patients reported experiencing mainly a warm sensation, with only brief stinging feelings in areas where the bones are more prominent, such as the jawline and Forehead. Dr. Zhao would adjust the energy level or treatment technique in advance for these areas, making the procedure much more comfortable than I had expected. For more information about the treatment itself, you can check out the South Korea Medical Aesthetic Devices Encyclopedia, which covers 8 popular devices including Thermage and HIFU.
Q4: Can foreigners make appointments? What do they need to prepare?
Yes, foreigners are more than welcome. It’s recommended to book 2–3 weeks in advance through BeautsGO or LINE. Bring your passport on the day of the appointment and go without makeup; avoid using acidic skincare products and exfoliants 3 days before the procedure.
Q5: How soon can you see results after the treatment? How long do they last? Thermage
FLX delivers gradual results: there’s an immediate tightening effect right after the procedure (about 20-30%), with more noticeable outcomes appearing after 1 month (around 60-70%), reaching peak effectiveness at 3 months. The overall effects typically last between 12 and 18 months, depending on each individual’s Collagen regeneration rate and lifestyle habits.
Q6: Are the prices at Cheongdam OKAY Dermatology considered high in Gangnam? F
or the original American-made Thermage FLX, the price at Cheongdam OKAY falls into the “moderately reasonable” range in Gangnam. It’s a bit more expensive than large chain clinics (since treatments are performed personally by the director), but much cheaper than those premium clinics that only serve VIP clients. The Oligio version priced at ₩440,000 is an extremely affordable option for those with limited budgets who still want to experience RF lifting.
Q7: What if I can’t get a appointment with Dr. Zhao? At Cheongdam OKAY De
rmatology, Dr. Zhao Xi-en is the only physician on staff, so there’s no possibility of being assigned to another doctor if you can’t book an appointment with the chief physician. If your time is flexible, it’s better to schedule an appointment during weekdays as it’s easier to get one then. If you can only make appointments on weekends, be sure to reserve one at least a month in advance.

How to Make an Appointment at Cheongdam OKAY Dermatology
Cheongdam OKAY Dermatology currently offers three ways to schedule appointments. Foreign visitors are advised to use the BeautsGO platform or LINE first, as it allows them to communicate their needs in Chinese in advance, helping to avoid language barriers at the clinic.
- LINE Online Consultation Booking: After adding the official LINE account, you can describe in Chinese or English the treatment you’re interested in. The clinic will respond during business hours and help arrange a suitable time. This option is ideal for those who need detailed consultations or aren’t sure which treatment is right for them.

5 Common Mistakes to Avoid When Visiting OKAY Dermatology in Cheongdam (Learned from Real People’s Painful Experiences)
- Don’t wait until you’re in Seoul to make an appointment: OKAY in Cheongdam only sees one patient at a time per slot. During peak seasons—summer (July–August) and the end of the year (December)—it’s quite common to have to wait 2–3 weeks for an appointment. Many people decide to “stop by” once they arrive in Seoul, only to find it impossible to get an appointment and end up making the trip for nothing.
- Avoid wearing makeup when going to the clinic: The face needs to be thoroughly cleaned before receiving Thermage treatment, and wearing makeup means wasting time on removing it. Since your face might turn slightly red after the procedure, it’s advisable to bring a hat and mask as backup.
- Don’t expect an immediate V-shaped face result—this isn’t thread lifting or Botox. Thermage’s effects develop gradually over 1–3 months. If you’re hoping to look great in photos right after the treatment, then this procedure isn’t suitable for you. Dr. Zhao will make this point clear during your consultation.
- Don’t ask for too low an energy level just because you’re afraid of pain—too low an energy level will indeed reduce the effectiveness of the treatment. Director Zhao will determine the most suitable energy level within acceptable limits, so trust her professional judgment. If you’re really worried about pain, feel free to let her know in advance; she’ll help adjust the timing of the anesthetic application for you.
- Avoid drinking alcohol or using saunas on the day of the procedure: Stay away from alcohol, hot baths, saunas, and strenuous exercise for 24 hours after the surgery. Many people think since their face doesn’t hurt or itch, they can go ahead and eat barbecue or drink sake—this can reduce the effectiveness of the treatment and even cause unnecessary swelling.
What should you prepare for your first visit to Cheongdam OKAY Dermatology? Pre- and post-surgery tips
Preoperative Preparation
- Make your reservation 2–3 weeks in advance, and confirm the date and service through BeautsGO or LINE.
- Avoid using acidic skincare products (AHA, fruit acids, salicylic acid) and exfoliating agents 3 days before the procedure.
- Avoid excessive sun exposure one week before the procedure. If you’ve just returned from a vacation on an island, it’s recommended to wait until your skin has stabilized before scheduling the appointment.
- Provide medical history: Are you taking aspirin or anticoagulant drugs? Do you have a tendency to develop telangiectasias?
- Go without makeup on the day of the procedure, and don’t apply sunscreen (the clinic will clean your skin before the treatment).
- Prepare a hat and mask to help cover any possible redness after the procedure.
Post-surgery precautions
- Within 24 hours after the procedure: avoid alcohol, hot baths, saunas, and strenuous exercise.
- Within 3 days after the procedure: Strengthen moisturization by using gentle skincare products (the post-procedure care kit provided by the clinic is recommended).
- Within 1 week after the procedure: Avoid exfoliation and use skincare products containing acids or whitening ingredients.
- Throughout the post-surgery period: Sun protection is crucial! If you don’t protect your skin from the sun during the Collagen regeneration phase, the risk of pigmentation increases.
- Within 1 month after the procedure: You can perform gentle facial massages (to promote blood circulation), but avoid applying strong pressure or going to a spa for facial treatments.
- The results after the procedure develop gradually, so there’s no need to worry by staring at yourself in the mirror every day. Give the Collagen 2–3 months to regenerate on its own.
The Real Verdict: Is It Worth Going to South Korea for the Korean Version of Thermage FLX in Cheongdam?
After dedicating an entire article to this topic, my conclusion is actually quite simple: if what you’re looking for is the “cheapest” Thermage treatment, Cheongdam OKAY isn’t the top choice. But if you’re aiming for the Thermage experience that will give you the least amount of regrets, this clinic is truly hard to beat.
From the environment, the doctors’ expertise, the post-treatment results to the overall experience, Cheongdam OKAY gave me the impression that it’s not just selling a treatment service, but building a long-term relationship of trust. Director Zhao won’t rush through the procedure just because you’re a tourist—after all, she knows that the outcome for you will determine her reputation—and she certainly won’t hurry things along just because you’re not a VIP International client. This attitude of treating every patient as unique is truly rare in the highly competitive medical aesthetics market of Gangnam.
If you, like me, are most worried about in medical aesthetics—not pain or high costs—but the result looking unnatural or fake after treatment, then Thermage FLX from OKAY Dermatology in Cheongdam is definitely the perfect place where you can trust them with your treatment.
