✈️ If you are considering flying to South Korea for a Thermage treatment, the real reviews of Thermage and Potenza at Lumiin Dermatology in Gangnam District, Seoul, are definitely worth spending 5 minutes reading! This clinic, which boasts only 2% of the “Red Label Certified” dermatologists in South Korea, offers Thermage FLX full-face treatments starting from 1.8 million South Korean won for 900 sessions. With a Google rating of 4.9 stars, it has become one of the most highly discussed options for cosmetic treatments in Gangnam among customers from Hong Kong, Taiwan, and other regions in 2026. This article will provide a detailed breakdown of Lumiin’s Thermage prices, consultation process, real customer reviews, and post-treatment recovery information, so you can be fully prepared before your trip.
I. Who is Lumiin Dermatology? Only 2% of dermatology specialist teams are located in Gangnam District.
💡 In South Korea, the title of “Dermatology Specialist” is not one that any doctor can claim casually. Less than 2% of doctors in the entire country have obtained this “red-label certification” after completing over 10 years of specialized training and passing the corresponding examinations. Lumiin Dermatology has managed to bring together three such specialists for joint consultations, a configuration that is extremely rare even in the highly competitive Gangnam area.
Each of these three specialist doctors has their own areas of expertise.
👨⚕️ Dr. Choi Jae-won (Practice Director): Specializes in the treatment of pigmentation disorders and skin anti-aging treatments. He is highly skilled in addressing issues such as age spots, solar lentigines, and persistent freckles, and also has extensive expertise in photothermal anti-aging therapies such as Thermage and HIFU. Many customers from Hong Kong and Taiwan travel specifically to South Korea just for Dr. Choi’s expertise.
👩⚕️ Dr. Yin Zhishan: Specializing in the treatment of acne-prone skin and the reduction of fine lines, she has conducted extensive research in acne prevention, scar repair, and post-treatment skin care. She is the top choice for many patients with oily and acne-prone skin.
👨⚕️ Dr. Cui Zhihao: Specializes in treating difficult-to-treat skin conditions such as vitiligo and psoriasis. With extensive clinical experience, he offers interdisciplinary integrated treatment plans for complex skin cases.
2. Why choose Lumiin for Thermage treatment?
🎯 If you want to know more about the effects and actual experiences of Lumiin’s Thermage treatment, you can read our detailed reviews. Thermage is a procedure that requires great expertise and skill from the practitioner – the angle of the probe, the control of energy delivery, and the distribution of treatments all directly affect the final results. Lumiin’s three specialist doctors adopt a “joint consultation” approach, offering customized solutions tailored to different skin issues, rather than following a standardized, assembly-line procedure. What’s more, Dr. Choi Jae-won always performs a preliminary marking process before starting the Thermage treatment to ensure that every dose of energy is applied precisely where it is needed.

II. Technical Principles of Thermage FLX Generation V | A New Benchmark in Scientific Anti-aging Technologies
🔬 If you are not yet familiar with the detailed technical specifications and selection guidelines of South Korea’s FLX Fifth-Generation Thermage, let us explain it in the simplest terms. Thermage FLX (the fifth-generation Thermage) is the latest generation of radiofrequency skin tightening equipment developed by the American company Solta Medical. Its core principle relies on Monopolar RF technology to deliver heat energy precisely to the dermis and subcutaneous tissues at deeper levels of the skin. This process causes Collagen to contract immediately while triggering a long-term mechanism for collagen regeneration.
What do the three letters FLX represent?
📋 F (Faster): The treatment head of the fifth generation has a 33% larger area compared to the fourth-generation CPT, resulting in a approximately 25% reduction in the time required for each treatment. For a full face treatment using 900 pulses, the entire process can be completed in just 40–50 minutes, significantly improving the efficiency of consultations.
📋 L (Algorithm, for greater precision): AccuREP™ intelligent impedance detection technology enables real-time scanning of the impedance values of every inch of skin, automatically adjusting the output energy to ensure that each treatment is precisely targeted, thereby significantly reducing the risk of overheating or uneven energy distribution.
📋 X (Experience, greater comfort): Equipped with built-in vibration alerts and a cooling protection system, it sprays refrigerant before and after the delivery of RF energy, reducing the burning sensation and pain during treatment. Overall, the comfort level is increased by over 40% compared to the fourth generation.
2. How to choose between Thermage, HIFU, and Potenza?
🆚 Many customers ask: Which is better, South Korea’s Thermage or the HIFU? Here is a comprehensive comparison of their effects, prices, and suitable candidates. Simply put, these three technologies operate at different levels, and there is no such thing as one being inherently better than the others. The key is to choose based on your specific needs:
💡 If your main concerns are facial sagging, deepening of the Nasolabial Fold Correction, or blurred jawlines, Thermage FLX is the most direct solution for you. If you also experience significant sagging, you may consider a combined treatment using Thermage and HIFU – this is also the gold standard combination frequently recommended by Lumiin Dermatology.
III. Complete price list for Lumiin’s Thermage treatments | Starting from 1.8 million Korean won – understand all the options at a glance
💰 Price is always a topic of great concern to everyone. Let me state the conclusion right away: At Lumiin Dermatology, the Thermage FLX full-face treatment uses 900 treatment sessions and costs starting from 1.8 million Korean won (approximately NT$41,000, HK$10,200, or CNY$9,500). This price is considered mid-to-high-end in the Gangnam area, but considering that the treatment is performed by specialized dermatologists using original FLX equipment, the cost-performance ratio is actually very high.
1. Various options and reference prices
⚠️ The above are merely reference price ranges. The actual fees may vary depending on an individual’s skin condition, the scope of treatment, and any promotional offers available in that month. The final price will be subject to the clinic’s daily quotation. You can check the latest prices through BeautsGO before making a reservation.
2. What does 1.8 million Korean won include?
✅ At Lumiin Dermatology, the Thermage FLX full-face treatment with 900 treatment sessions typically includes the following services:
1. One-on-one consultation with a specialist doctor: A Dermatology specialist will personally assess your skin condition, degree of sagging, and treatment needs to develop a personalized treatment plan for you.
2. MarkView Skin Analysis: Utilizes an advanced skin diagnosis system to conduct scientific analyses of skin type, thereby eliminating the blind spots associated with empirical judgments.
3. 900 original FLX probes: These probes are manufactured by Solta Medical in the United States and are designed to be used once only. Each probe comes with a unique serial number, and their authenticity can be verified on the official website.
4. Post-treatment Sedative Recovery Care: After the treatment, professional sedative masks and recovery care products are provided to help the skin recover quickly.
5. Post-treatment follow-up and consultation: If you have any questions after the treatment, you can consult our Chinese-speaking customer service to monitor your recovery progress.

IV. The process of visiting Lumiin for the first time | A detailed record of the entire experience, from appointment to post-operative care
🏃 If you are new to the medical beauty industry in South Korea and want to avoid making any mistakes from the booking process to the post-treatment period, this is the first lesson you must read. Below, we take the Thermage full-face treatment with 900 treatment sessions as an example to thoroughly explain every step involved in the entire process.
1. Booking and Preparations Before the Procedure
📅 Step 1: Choose your reservation method. If you want to learn about the complete reservation processes at Lumiin Dermatology – including options via BeautsGO, LINE, and the official website – we previously published a detailed guide with illustrations. We recommend using the BeautsGO APP or the WeChat mini-program, as they allow you to view the current price list and promotional offers for the month. When making a reservation, you need to pay a deposit of 20,000 Korean won (approximately NT$460), which can be fully deducted when you undergo the treatment.
📅 Step 2: Confirm the treatment time. Lumiin is open from 10:00 AM to 8:00 PM on weekdays, and from 9:30 AM to 3:30 PM on Saturdays. It is closed on Sundays and public holidays. It is recommended to make a reservation at least 1-2 weeks in advance, as the number of slots is limited during peak hours, especially on weekends in the morning.
📅 Step 3: Preparations before the procedure. One week before departure, avoid using irritating skincare products such as retinol or fruit acids; on the day of the treatment, do not wear heavy makeup—it is recommended to go without makeup or with light makeup to facilitate the doctor’s skin examination.
2. In-person consultation and MarkView skin examination
🔍 Upon arrival at the clinic, you will first be greeted by a Chinese-speaking translator who will assist you in filling out basic information forms and consent documents. Next, you will undergo a examination using the MarkView skin diagnostic system—a scientific instrument capable of providing in-depth analysis of your skin condition, as well as the type and depth of any pigmentation abnormalities. This enables doctors to rely on objective data when determining your treatment plan, rather than making judgments solely based on visual observation.
👨⚕️ After the skin examination, Director Cui Zaiyuan or the on-duty specialist will conduct a personalized consultation to assess the degree of skin laxity, thickness, and sensitivity. They will also discuss the treatment goals and the number of hair grafts to be used. The director will personally mark the treatment areas by drawing lines.
3. The treatment process of Thermage
⚡ Before the treatment, medical staff will clean your face, apply an anesthetic ointment (for about 30 minutes), and place protective eye masks over your eyes. Once the treatment begins, the doctor will administer the treatments one by one in the designated areas; each session lasts approximately 2–3 seconds, accompanied by a brief sensation of heat followed by the cooling effect of the coolant. The entire process, which involves 900 treatments across the entire face, takes around 40–50 minutes to complete.
💬 During the process, the doctor will constantly ask you how you are feeling and adjust the intensity of the energy. If any particular area is particularly sensitive – such as the jawline or the sides of the Forehead – you can immediately let the doctor know, and they will reduce the energy level or increase the amount of coolant being sprayed accordingly.
4. Immediate post-treatment care and precautions
🧊 After the treatment, your face may experience noticeable redness and slight swelling – these are normal immediate reactions that usually subside within 2 to 4 hours. The medical staff will apply a soothing and restorative mask to your skin and provide detailed instructions for post-treatment care. You can wash your face and apply light makeup on the same day, but it is recommended to avoid strenuous exercise and high-temperature environments (such as hot baths or saunas).

V. Real experiences rated 4.9 by users | Summary of reviews from PTT/Dcard/Google
⭐ Lumiin Dermatology has received an impressive rating of 4.9 stars on Google Maps, which places it among the top institutions in the highly competitive Gangnam area. Below are some genuine reviews gathered from various platforms:
1. Selected Real Reviews from Google Maps
👍 A customer from Hong Kong shared: “I went to Lumiin for a Thermage treatment on my entire face. Director Cui personally examined me, and a Chinese translator was available throughout the process, which made me feel very at ease. One month later, the Nasolabial Fold Correction results were already noticeable – my friends all said I looked 5 years younger!”
👍 Another Taiwanese customer wrote: “I was originally very worried about language barriers, but in the end, I didn’t have to worry at all. From the appointment to the post-treatment follow-up, everything was provided in Chinese. The MarkView skin examination is very professional; the director even takes the time to explain the results in detail to you, which is completely different from other clinics that just send you away after a few minutes.”
2. Organization of PTT/Dcard discussions
💬 On the Korea_Travel version of PTT and the medical beauty section of Dcard, discussions about Lumiin have always been very active.
💬 Netizen A (PTT): “I compared 5 clinics in the Gangnam area that offer Thermage treatments and finally chose Lumiin. The cost-performance ratio was the best, and the director personally performed the procedure instead of entrusting it to a nurse – this is really important in South Korea’s medical aesthetics industry. It’s been half a year since the treatment, and the results are still lasting.” (March 2026)
💬 Netizen B (Dcard): “I felt that the service was excellent when making the reservation – the responses were quick, and they proactively provided me with important notes. When I actually arrived at the clinic, I was truly impressed: the environment was clean and bright, and there was no unpleasant smell of chemicals commonly found in such places. After the Thermage treatment combined with Potenza, my Pores became significantly smaller!” (April 2026)
💬 Netizen C (PTT): “1.8 million yuan for a full-face treatment with 900 hairs implanted; Director Cui handles the procedure, includes Chinese translation services, and uses MarkView for verification. At this price in Gangnam, it’s practically a bargain. Moreover, there are no additional consultation fees, and the reservation fee can even be used as a discount.” (May 2026)
3. Key points from the comprehensive reviews of customers from Hong Kong and Taiwan
📊 Based on reviews from various platforms, customers’ positive feedback regarding Lumiin mainly focuses on the following aspects:
1. Performed personally by specialized medical professionals: No nurses or beauticians doing the work on behalf of them, ensuring maximum peace of mind.
2. Barrier-free Chinese services: From consultation to post-operative follow-up, all services are provided in Chinese, which is extremely convenient for overseas customers.
3. Transparent pricing with no hidden fees: All costs are clearly stated in advance, with no additional surcharges or price increases.
4. Scientific testing to assist in diagnosis: The MarkView system provides data-driven support for treatment, rather than relying on subjective assumptions.
5. Clean and comfortable environment: Located on the 3rd floor of the SH Building in Gangnam District, the overall atmosphere is professional and upscale.
⚠️ Some customers have suggested the following improvements: It is more difficult to make appointments on weekends (it is recommended to book at least 2 weeks in advance), and the waiting time can sometimes be longer (since the director personally attends to each patient, more time is allocated for each customer).
VI. Who is BARUNGYN suitable for? A must-read pre-operative assessment guide
👤 Not everyone is suitable for Thermage treatment. The following is a detailed analysis of who is and who is not suitable, to help you make an informed decision before proceeding:
1. Suitable for a wide range of people ✅
1. For individuals aged 25 to 55 who experience mild to moderate skin laxity: early signs of aging such as deepening of the Nasolabial Fold Correction, blurred jawlines, and sagging cheeks.
2. For young and middle-aged individuals who wish to prevent premature aging: Starting to undergo Thermage treatments regularly around the age of 30, once every 12–18 months, can effectively slow down the loss of Collagen.
3. For those who do not want to undergo invasive surgeries: Thermage is a non-invasive treatment that requires no surgery or recovery period, making it ideal for those who wish to enhance their appearance discreetly without anyone noticing that they have undergone cosmetic procedures.
4. For those who wish to return to their normal daily routine immediately after the procedure: You can apply makeup and go to work on the same day, with no impact on your social activities or work.
5. Advanced users with prior experience in medical aesthetics who wish to upgrade their anti-aging treatments: Those who have already undergone basic procedures such as hyaluronic acid injections or Pico treatments and want to further improve the definition of their features and the firmness of their skin.
2. Not suitable for/can’t be used by certain groups of people ❌
1. Women who are pregnant or breastfeeding: For safety reasons, it is not recommended to undergo Thermage treatment during pregnancy or breastfeeding.
2. Individuals with cardiac pacemakers or metal implants in their bodies: RF energy may interfere with electronic medical devices.
3. For individuals with open wounds or severe skin infections in the treatment area: It is necessary to treat the skin issues first, and only after recovery should a further assessment be conducted.
4. Patients with autoimmune diseases: Such as systemic lupus erythematosus and scleroderma, etc. A doctor’s evaluation is required before making a decision.
5. Those who have unrealistic expectations regarding the treatment results: Thermage is intended to “improve” rather than “transform the face” completely; its effects involve a gradual process of collagen regeneration, not immediate results like those achieved through surgical facelifts.
3. Preoperative Preparation Checklist 📋
1. Make a reservation 1-2 weeks in advance through BeautsGO or WeChat to confirm the date and the doctor.
2. Stop using irritating skincare products such as retinol, fruit acids, or high-concentration vitamin C one week before your trip.
3. Three days before the treatment, avoid any activities that may irritate the skin, such as excessive sun exposure, exfoliation, or laser treatments.
4. On the day of the appointment, wear comfortable clothing; it is recommended to go to the clinic without makeup.
5. Make sure you have your passport and mobile phone ready (they will be needed for translation and taking photos for documentation).

VII. Recovery Period After Thermage Treatment | A Complete Record of Changes from Day 1 to 3 Months
📆 What many people want to know most is: how long does it take to see the results after undergoing Thermage treatment? The following records show the actual changes at different stages after the procedure:
Immediate post-treatment reactions (Days 0-3)
🔥 After the treatment, the face will show obvious redness and a warm sensation, similar to the effect of mild sunburn. This is a normal reaction resulting from the radiofrequency energy acting on the dermis. Some people may experience slight localized swelling, which usually begins to subside within 2 to 4 hours. Immediate tightening effects of about 10% to 20% can be observed on the same day; this is due to the immediate contraction of Collagen fibers under the influence of heat energy.
2. Effect manifestation period (Weeks 1-4)
🌱 In the first week after the procedure, the immediate Lifting effects may diminish slightly, but this is a normal phenomenon and there is no need to worry. Starting from the second week, the body’s natural Collagen regeneration process kicks in, and the skin will gradually become fuller and more elastic. By the third to fourth week, additional benefits such as smaller Pores and more even skin tone begin to become visible.
3. Peak Effect Period (Months 1-3)
🌟 One month after the procedure, the tightening effects begin to become stable: the Nasolabial Fold Correction becomes less noticeable, the position of the Apple Zone is elevated, and the jawline becomes more defined. After 2–3 months, the results reach their peak – Collagen production reaches its maximum, and the facial contours become significantly more IPCHEA and youthful. The overall effects can last for approximately 12–18 months, after which another treatment can be scheduled according to individual needs.
VIII. Why choose Lumiin for Thermage treatment? A summary of 5 key reasons
🏆 Based on the above analysis, here are five key reasons for choosing Lumiin Dermatology for Thermage treatments:
▲ Overview of the environment at Lumiin Dermatology
IX. Frequently Asked Questions
1. Will Thermage be painful? Is anesthesia necessary? 💉
💬 The Thermage FLX model is equipped with an integrated cooling system. During treatment, there may be a brief sensation of heat (similar to the impact of a rubber band), but the overall level of discomfort is approximately 40% lower than that of the fourth-generation CPT device. An anesthetic ointment is applied about 30 minutes before the treatment, and most people find it easy to tolerate.
2. How long does it take to see the results after undergoing Thermage treatment? And how long do these results last? ⏱️
💬 Approximately 10–20% of the immediate tightening effects can be observed on the same day after the procedure. The true effects of Collagen regeneration begin in the second week and reach their peak at 2–3 months. The complete results can last for around 12–18 months, after which it is recommended to undergo a maintenance treatment once a year.
3. Is Lumiin’s Thermage a genuine FLX device? How can I verify this? 🔍
💬 Yes, Lumiin uses the Thermage FLX equipment officially licensed by Solta Medical in the United States. Each treatment probe comes with a unique serial number, and its authenticity can be verified on the Thermage official website. You are also welcome to request to see the packaging of the equipment and probes before the treatment begins.
4. What expenses are included in the 1.8 million Korean won? Are there any hidden costs? 💰
💬 The standard price for a full-face treatment with 900 hairs is 1.8 million Korean won, which includes the doctor’s consultation fee, MarkView skin examination fee, treatment costs, and post-operative sedation care fees.

6. Can Thermage and HIFU be used together? Which one should be done first? 🔄
💬 Sure! Thermage (acting on the dermis) combined with HIFU (acting on the SMAS fascia layer) is a golden combination recommended by many doctors. It is generally suggested to perform Thermage first (taking approximately 40–50 minutes), followed by HIFU (about 30–40 minutes), in order to achieve tightening and lifting effects at both deep and superficial layers in one session. However, a doctor should first assess whether your skin condition is suitable for this combined treatment.
7. Is special care required after the procedure? Can I apply makeup immediately afterwards? 💄
💬 On the day after the procedure, you can wash your face, apply skincare products, and wear light makeup as usual. It is recommended to avoid exfoliation, skincare products containing acids or high concentrations of vitamin C, as well as exposure to high-temperature environments (such as saunas, hot springs, or intense exercise) for at least one week after the treatment. Additionally, make sure to enhance your sun protection and moisturization routine.
