In the core area of medical aesthetics in Gangnam, Seoul, there is a newcomer—South Korea’s DIar Dermatology. Although it was established only in 2025, it has quickly risen to the forefront of reputable Dermatology clinics in Gangnam thanks to the 26-year of extensive experience of its director, Liu Zhuangxi, and its state-of-the-art “Thermage + HIFU dual-device setup.” This clinic is nothing like a mass-produced establishment; rather, it is a boutique practice where “experienced doctors establish their own independent practices and rely on their expertise to speak for themselves.” This article provides a comprehensive overview of DIar Dermatology’s location, director, services, prices, and how to make an appointment.

Chief Physician: President Liu Zhuangxi (with 26 years of experience)
The soul of DIAR Dermatology is its director, Liu Zhuangxi. With 26 years of experience in the Dermatology field, he is widely recognized in South Korea as a “master of photothermal equipment operation.” Whether it comes to the precise control of the energy output of Thermage FLX or the accurate targeting of the SMAS fascia layer using the Ulthrea, he possesses extensive clinical experience, having performed thousands of procedures in these areas.
What patients admire most about Director Liu is his medical principle of “only performing procedures personally myself and never entrusting assistants to do it on my behalf.” At DIar, all treatments are conducted under Director Liu’s direct supervision, which is already a rare practice among Dermatology clinics in the Gangnam area. His philosophy of treatment is: “I would rather see fewer patients each day than ensure that every patient receives personal attention from the director himself.”
For this very reason, diar implements a strict reservation system, with a limited number of consultations available each day. During the peak season, it is necessary to make a reservation 1-2 weeks in advance.
Core technical equipment of DIar Dermatology
1. The fifth-generation Thermage FLX in the US version
DIar has introduced the world’s most advanced fifth-generation Thermage FLX system. Compared to previous generations, the FLX model utilizes AccuREP technology, which enables it to instantly detect differences in electrical resistance across different skin areas. This technology dynamically adjusts the output of radiofrequency energy, ensuring uniform heating of deeper layers of collagen and preventing the two extreme problems of “overheating and burns” or “insufficient heating and ineffectiveness.”
Director Liu’s 26 years of experience in operating medical equipment enable him to accurately set personalized energy parameters for each patient—this is precisely the reason why “the same machine can produce vastly different results when used by different doctors”.
Reference price for DIAR Thermage: 900 hairs for the entire face, starting from approximately 500,000 Korean won (equivalent to around 2,650 RMB).
2. Second-generation Ulthrea (Ultherapy Solta)
The diar is equipped with the second-generation Ulthrea, which represents the most technologically advanced and precisely designed version among HIFU devices. Its focused ultrasonic energy can be precisely targeted at depths of 3.0mm and 4.5mm within the skin, corresponding to the dermis and SMAS fascia layers respectively, thereby achieving a “dual-layer Lifting” effect. This makes it particularly suitable for individuals suffering from moderate to severe facial sagging, noticeable neck wrinkles, or blurred jawlines.
Reference price for DIAR beauty treatments: Starting from approximately 400,000 Korean won per 300 sessions (equivalent to approximately 2,120 RMB).
3. Titanium Lifting
In addition to Thermage and Medelite, diar has also introduced Titanium Lifting technology from Israel’s Fractone. This treatment uses multi-wavelength lasers combined with sapphire cooling technology to target the dermis and subcutaneous tissues. It causes minimal discomfort, requires almost no recovery time, and allows patients to apply makeup immediately after the procedure. It is particularly suitable for people who are afraid of pain or have busy work schedules.
4. Injection-based cosmetic treatments (Lizulan, Juvederm, JUVELLOOK)
DIar offers a full range of top-quality injection products, all of which are officially certified as genuine products.
- REJURAN series: PDRN Salmon DNA repair needles – improve skin quality, reduce Pores, and reverse the signs of early aging.
- Juvéderm/Restylane: Filler injections for Nasolabial Fold Correction, Apple Zone enhancement, and chin reshaping.
- JUVELOOK DongAn Center Introduction Needle: PCL microspheres stimulate collagen regeneration, filling in depressions, with effects lasting for over 2 years
5. Thread Lifting (multiple brands)
DIar offers a range of brand-specific thread lifting services, including Silhouette Soft Bell-shaped Threads, Jamber Thread, and MINT threads. Dr. Liu recommends the most suitable type of thread based on the individual’s degree of facial relaxation. The Bell-shaped Threads are particularly suitable for those who have prominent Nasolabial Fold Correction areas and desire long-lasting, natural results (the effects can last for 18 to 24 months).
6. ONDA microwave Coolwaves (lipolysis and face slimming)
DIar has introduced the Onda Coolwaves microwave technology, which is originally imported from Italy. This is a high-end lipolysis technique that is relatively rare in Dermatology clinics in South Korea today. By precisely applying microwave energy to fat cells, this technology induces their natural apoptosis and metabolism without damaging the surrounding tissues, thus achieving safe facial slimming and eliminating the Double Chin with virtually no recovery period required.

The five core strengths of DIar Dermatology
The dean, with 26 years of experience, takes personal charge of everything.
The greatest differentiating advantage of DIar lies in the 26 years of extensive experience accumulated by Director Ryu Jang-sik. From the earliest laser treatments to the current Thermage FLX technology, he has virtually witnessed and personally participated in the entire evolution of dermatology and cosmetic medical equipment in South Korea. This clinical expertise is reflected in the precision and safety of treatments provided to each patient.
2. A combination of flagship equipment and scarce technologies
The combination of Thermage FLX, the UltraS Plus laser, and ONDA microwaves covers the entire anti-aging process, ranging from “tightening and Lifting” to “deep fascia lifting” and “lipolysis for face slimming.” Moreover, the ONDA microwave device is relatively rare in Dermatology clinics in Seoul, giving DIar a competitive advantage in terms of technical options.
3. A scientific service process involving a six-step closed-loop system
DIar follows a rigorous “scientific procedure implementation” process: medical history assessment → skin examination → texture analysis → consultation with a physician to finalize the treatment plan → treatment procedure → post-treatment care guidance and regular follow-ups. Every step is documented to ensure the systematicness and traceability of the treatment process.
4. Double certification for genuine materials
All injection materials used by diar, such as Restylane, Juvederm, Hyaluronic Acid, and JUVELOOK, have undergone formal approval by the South Korea Food and Drug Administration. We also provide batch number verification services to ensure that patients can use these products with confidence.
5. Comprehensive Chinese-language services
DIar provides comprehensive Chinese-speaking guidance throughout the entire process, from appointment booking to in-hospital consultations and post-operative care instructions. All communications can be conducted in Chinese, and detailed written instructions for post-operative care are also provided in Chinese.
