To be honest, when considering medical aesthetics treatments in South Korea, most people focus on factors such as “price”, “which treatment is effective”, and “what the environment of the clinic is like”. However, there is one thing that is even more important than all these: who the person operating the equipment is, and what their background is. Dr. Kim Han-gil, the director of Sinsa Theippo Dermatology, has over 15 years of clinical experience in Dermatology after graduating from Yonsei University. He does not follow a standardized procedure or delegate tasks to younger doctors. This article does not discuss prices or the clinic’s facilities; instead, it focuses on Dr. Kim’s educational background, treatment approach, and real patient reviews, providing you with a comprehensive understanding before making a decision. Sisters who are still hesitating about whether to visit Theippo should first get to know the doctor before making a choice.
Who is Director Kim Han-gi of the Sinsa Theippo Dermatology clinic? A detailed introduction to his educational background.
👑
Director Kim Han-gil is a Dermatology specialist who graduated from the School of Medicine at Yonsei University in Seoul, South Korea. The reputation of Yonsei University in the field of medicine in South Korea is well-known – it is considered one of the three top medical institutions in the country, alongside the School of Medicine at Seoul National University and the School of Medicine at Korea University. The number of places available for dermatology residency programs at Yonsei University is extremely limited each year, so graduating from this program in itself constitutes a strong credential.
After graduating, Dr. Kim worked at several well-known Dermatology clinics in Seoul, gaining experience in everything from basic skin care to advanced anti-aging laser treatments. Over the course of 15 years, he accumulated tens of thousands of clinical cases in areas such as non-invasive lifting treatments (Thermage FLX, Ultherapy), injectable cosmetic procedures (botulinum toxin, Filler, lipolytic injections), and laser phototherapy. Unlike many young doctors who attempt to do everything but specialize in anything particular, Dr. Kim focuses solely on the areas he truly excels in, rather than taking on treatments he is not proficient in just to earn more money.
The most crucial point is that Director Kim Han-gyung is the type of director who personally performs all the procedures at the theippo Dermatology clinic. In South Korea’s medical aesthetics market, many clinic directors merely hold the title or are responsible for conducting consultations, while the actual procedures are carried out by nurses or less experienced doctors – but not at the theippo clinic. On the day I visited, from the consultation to the actual treatment, everything was done solely by Director Kim. While a nurse assisted in handing over the equipment and applying post-treatment ice packs, no one else touched the devices or operated the probes throughout the entire process. This is particularly important for treatments such as Thermage FLX or lipolysis injections, which rely heavily on the practitioner’s expertise.
Director Kim Han-ji’s treatment philosophy: No mass production; only personalized solutions for each individual case.
💡
If I were to summarize Director Kim Han-gyn’s treatment approach in one sentence, I would say: “He doesn’t rush time.” This is a profound realization I had after visiting many Dermatology clinics in South Korea. Some clinics treat each patient in just 3 minutes of consultation and 30 minutes of treatment before moving on to the next client, with the entire process designed solely to maximize the number of treatments completed per day. However, Director Kim’s approach is completely different. Here are his three main treatment features:
① 面診不趕時間，先分析再決定做什麼
President Jin’s consultation process is as follows: first, he visually examines the condition of your face, then asks about your concerns and expectations (during the communication in Chinese, translations via text messages or gestures can be used for assistance). Next, he uses skin testing equipment to assess the degree of Collagen loss and the areas of sagging, and only finally provides treatment recommendations. The entire consultation takes approximately 15–20 minutes, and he will not perfunctorily handle it just because you are a foreigner. If he determines that a particular treatment is not suitable for your current skin condition, he will directly tell you so, rather than proceeding with it just to make a profit.
② 能量打法保守中帶精準，安全第一
When using high-energy devices like Thermage FLX, many doctors deliberately increase the intensity to ensure that patients can immediately notice the effects after the treatment. However, this is actually very dangerous, as excessive energy can easily cause burns, blisters, or even fat atrophy and indentation. Dr. Kim’s approach is to start with medium to low levels of energy and gradually increase it to the therapeutic range only after determining your tolerance to the heat. After treating each area, he stops to check your reaction, rather than rushing through the entire treatment in one go. This “conservative yet precise” approach is actually more reassuring for those who are experiencing this treatment for the first time, are particularly sensitive to pain, or are concerned about potential side effects, compared to the more aggressive strategy of using high energy levels from the start.
③ 術後追蹤認真，不是做完就掰掰
Director Kim will personally explain the post-operative precautions to you (the instructions are in Korean, but the nurses or BeautsGO customer service can assist with the translation). He will also ask about your upcoming schedule (such as when you will take the flight) and provide specific post-operative care recommendations based on your time arrangements. If necessary, one month after the procedure, you can also rely on BeautsGO customer service to help you follow up with the director online—a service that many doctors in South Korea are unable to offer, as most dermatology practitioners in the country simply complete their treatment and do not provide any follow-up support.
Why is President Kim Han-ji’s background from Yonsei University so significant?
🏥
In South Korea’s Dermatology market, the educational background of physicians has a greater impact on the quality of treatments than in Taiwan. The reason is simple: there are an extremely large number of dermatology and cosmetic clinics in South Korea (just in the Gangnam area of Seoul, there are thousands of such clinics), and the fierce market competition has led to intense competition among them in terms of “price” and “speed”. In this environment, the educational qualifications and training backgrounds of physicians have become important criteria for distinguishing the quality of services provided.
The specialized training in Dermatology offered by the School of Medicine at Yonsei University has several key features:
- Solid clinical training – Eton Medical’s residency program in Dermatology emphasizes the principle of “diagnosing skin diseases first, and then proceeding with cosmetic treatments”, rather than skipping pathological diagnosis and directly focusing on instrument operation. This means that when dealing with patients’ skin issues, Director Kim analyzes them from the perspective of a “skin specialist”, rather than an “instrument operator”.
- There is an abundance of research resources in the field of anti-aging. Dr. Yan’s Dermatology research team has published numerous papers in areas such as Collagen regeneration, radiofrequency energy transmission, and the degradation of fillers. During his academic studies, Dr. Jin was exposed to cutting-edge theories in anti-aging, which greatly assisted him in later operating devices like Thermage FLX – devices that require a deep understanding of tissue heat conduction principles.
- With a strong alumni network, the alumni of Yonsei Medical University are distributed across South Korea’s top hospitals and clinics. As a result, they have greater access to resources such as equipment updates, technical exchanges, and discussions on complex cases than doctors from smaller institutions.
In simple terms, dermatologists graduated from Yonsei University generally possess more solid foundational skills than those working in ordinary clinics, and they tend to be more cautious when assessing risks. This may not necessarily be considered a “plus” (if what you’re looking for is immediate results), but for customers who prioritize safety and are unwilling to take risks, such a background is indeed very reassuring.
Director Kim Han-ji’s professional reputation in the field of Thermage FLX
🪄
In South Korea’s medical aesthetics industry, there is an unwritten “hierarchy” among doctors: some specialize in injections (botulinum toxin, Filler, lipolysis), some focus on lasers, while others specialize in radiofrequency devices. Director Kim Han-ji falls into the third category—he possesses unparalleled expertise in the use of Thermage FLX and Ultherapy, two of the most popular radiofrequency devices, and his skills are recognized among clinics in the Sinsa area of Gangnam.
Why is his Thermage FLX technology considered particularly reliable? There are several details that indicate this:
- Precise allocation of treatment spots – While many clinics use a standard template when applying Thermage FLX (XX treatment spots on the Forehead, XX on the cheeks), Dr. Jin will adjust the allocation based on your specific areas of relaxation. For example, since the area at the junction of my chin and neck was the most affected by sagging, he redistributed some of the treatment spots originally allocated to my Forehead to the lower half of my face, ensuring that the energy was focused where it was most needed.
- Masterful control over probe angle – The Total Tip 3.0 probe of Thermage FLX must be kept perfectly perpendicular to the skin surface to achieve optimal results; even the slightest deviation can reduce the efficiency of energy transmission. During the procedure, Dr. Jin’s precise control over the angle was evident, ensuring that the probe remained at a stable position at every point.
- Complete pre- and post-treatment comparison records — Before the procedure, theippo takes standardized photos for archiving. After the treatment, another set of photos is taken from the same angle and under the same lighting conditions to facilitate an objective comparison of the results. This is crucial for determining whether Thermage FLX is effective. Many clinics simply take a random photo before the treatment and do not conduct any comparison afterwards.

Summary of patients’ evaluations of Director Kim Han-ji
- Google Maps (rating: 4.8/5) — “Director Jin is extremely attentive; the treatment with Thermage FLX 600 requires plenty of time and cannot be rushed. During the consultation, communication in English was no problem at all, and he patiently explained the details of each treatment area. Two months after the procedure, the lines on my chin have indeed become much clearer – I am very satisfied.”
- Naver Blog — “The director personally handled everything, from the initial consultation to the actual treatment. In other hospitals, nurses might take over at some point, but here, the director did it all alone from start to finish. It was really meticulous, and I felt a great sense of trust.”
- Dcard — South Korea’s Medical Aesthetics Forum — “President Kim will never push you into undergoing procedures that are not suitable for you just to make money! When I went there, I originally wanted to get lipolysis injections, but after examining my face, he said, ‘What you need is radiofrequency treatment, not lipolysis.’ He’s really conscientious. It’s really rare to encounter a doctor in South Korea who doesn’t try to sell you unnecessary treatments.”
- Dcard — South Korea’s Medical Aesthetics Forum — “A reminder: President Kim can communicate in English, but he speaks very slowly and will only continue speaking once he’s sure you understand. If you don’t know any foreign languages at all, it’s recommended to make an appointment through BeautsGO; their Chinese-speaking customer service can help with translation, making communication much smoother.”
- PTT – Facelift Plate: “Before going to Thermoage FLX at the Thippo clinic, I checked the background of the director and confirmed that he graduated from Yonsei University and had 15 years of experience. It turned out that my research wasn’t in vain – Director Kim’s skills are truly excellent. After the treatment, I didn’t get any burns or blisters, and the improvement in the Double Chin area was particularly noticeable one month after the procedure.”
- REDnote: “Director Kim Han-ji is the kind of person who doesn’t talk much but is extremely focused. Unlike some directors who chat with the nurses while performing their tasks, his attention was entirely focused on your face and the screens of the medical devices. His level of concentration is truly remarkable and very reassuring.”
Director Kim Han-ji vs. The Assembly Line Clinic: What are the key differences between them?
⚖️
In South Korea, the term “assembly line” is almost synonymous with “medical aesthetics in South Korea” – but in reality, not all clinics in South Korea operate on an assembly-line model. Compared to the large chain clinics in the Gangnam area, Dr. Kim Han-ji’s theippo Dermatology has several fundamental differences.
| Comparative projects | Dr. Theippo Kim Han-gyung from Sinsa | Large-scale chain outpatient clinics with streamlined operations |
|---|---|---|
| Appointment time | Within 15 to 20 minutes, the director personally conducted the consultation. | Within 3 to 5 minutes, led by a consultant |
| The doctor performing the injection | The dean personally handled the entire process. | The doctor who conducts the face-to-face consultation is not necessarily the same as the one who performs the treatment; in some cases, the procedure may be carried out by a nurse. |
| Number of customers received daily | There are restrictions; scheduling must not exceed the permitted limits. | There is no upper limit; the turnover rate is the primary consideration. |
| Treatment plan | Personalized customization, adjusted according to actual circumstances | Standardized packages offer limited flexibility |
| Sales pressure | If the cost is too low, it may deter people from considering projects that are not suitable for them. | Mid-to-high level, with a tendency to add additional projects and increase the number of instances. |
| Postoperative follow-up | Yes, you can follow the progress through BeautsGO. | Almost none; it’s over as soon as it’s done. |
| Suitable for various groups | Emphasize the experience of doctors, avoid rushing, and strive for personalized services. | Striving for the fastest speed and the lowest prices |
To put it simply, President Kim’s Theippo is not the “ cheapest” option, nor the “fastest” one – it is the most reliable choice. If your greatest fear regarding medical aesthetics treatments in South Korea is being treated like a commodity on an assembly line, then Theippo will help you change your perspective entirely.

Frequently Asked Questions
Q: Does Director Kim Han-ji speak Chinese or English? Will there be any communication barriers?
A: Director Jin has a basic grasp of English communication, so it’s no problem for her to handle everyday medical beauty consultations in English—questions like “Does it hurt?” or “This area needs extra attention” can be easily addressed in that language. However, if you need to provide more detailed information about your skin type, previous treatments, or have any special requirements, it’s recommended that you schedule a consultation via WeChat Hannah972 or the BeautsGO platform. Our Chinese-speaking customer service staff can translate your requests in advance, ensuring a smoother conversation during the appointment. You can make an appointment for a consultation by contacting Hannah972 or BeautsGO through WeChat.
Q: Is the effect of Thermage FLX performed by Director Kim Han-ji different from that achieved by doctors in Taiwan?
A: Thermage FLX is a standardized device, and the output parameters of the machine itself are uniform. The differences in results mainly depend on the experience and techniques of the practitioner—including the strategy for distributing the number of treatments, the logic for adjusting the energy level, and the control of the probe angle. Director Kim has 15 years of experience in these areas, and compared to younger doctors, his expertise is particularly evident in terms of the “uniformity of results” and the “control of post-treatment reactions.” Additionally, since the price in South Korea is 40-60% lower than that in Taiwan, the overall cost-performance ratio is very favorable.
Q: How much in advance should one book a consultation with Director Han Ji?
A: Director Jin can only receive a limited number of clients per day. It is recommended to make an appointment at least 1-2 weeks in advance, as weekends are particularly popular. If the appointment is scheduled around a holiday (such as the Chinese New Year or Mid-Autumn Festival), it is advisable to book 3-4 weeks in advance. You can make an appointment through either BeautsGO or WeChat Hannah972. For detailed instructions, please refer to our comprehensive theippo reservation guide on this website.
Q: Besides Thermage FLX, what other treatments does Director Kim Han-ji specialize in?
A: In addition to Thermage FLX, President Jin also has extensive experience in facial lipolysis injections and basic skin care. When it comes to lipolysis injections, his approach involves applying the treatment in multiple layers, at various points, and in small doses to prevent uneven indentations or swelling. He also uses Ultherapy and various laser treatments, but his main focus remains on Thermage FLX and lipolysis injections.
Q: If Director Kim Han-ji was not available on that day, who would perform the procedure?
A: Theippo is a one-person clinic, with Dr. Kim Han-gyung as the sole practitioner. If he is on vacation or unavailable on a particular day, the entire clinic will not be open to receive patients—this is precisely how a “one-person clinic” operates. In other words, as long as your appointment is confirmed, it will definitely be Dr. Kim himself who performs the treatment; there will be no substitutes or replacements. For customers who value consistency in their treatment providers, this is a significant advantage.
