After comparing several options in the Gangnam Dermatology field, I finally chose DIAR. It’s really reassuring to know that each of the three directors specializes in different areas.

Before going to Seoul I for the cosmetic treatment this time, I looked at several Dermatology clinics in Gangnam on BeautsGO and finally added DIAR CLINIC to my schedule. To be honest, I initially chose it because it is located near Sinsa Station and has convenient transportation. But after taking a closer look, I realized that the team of experts at this clinic is truly outstanding—all three directors have been practicing in this field for over 20 years and are considered established figures in South Korea’s Dermatology community. Moreover, in recent years, INMODE radiofrequency body sculpting has become extremely popular in South Korea, and DIAR is one of the few clinics that offer both INMODE and Thermage FLX treatments. These factors convinced me to visit it in person.

First impression upon entering Dermatology at DIar: a professional atmosphere located beside Gangnam-daero

The diar is located on the 10th floor of the KI Building, at 8, 69 Gangnam-daero, Seocho-gu, Seoul. It is only about a 5-minute walk from Sinsa Station. Upon entering, the overall atmosphere reflects the clean, minimalist style typical of a high-quality clinic – without any excessive extravagance in decoration, but with all the necessary facilities in place. There are staff members who speak Chinese in the reception area, which is very helpful for foreigners.

The clinic is open from 10:30 to 20:00 from Monday to Friday, until 17:00 on Saturdays, and is closed on Sundays. It is recommended to make an appointment in advance on BeautsGO, as you generally won’t have to wait for long on the day of your appointment.

Each of the three directors is in charge of a different area, and after learning about their qualifications, I felt much more at ease.

The most prominent feature of DIar is its system of three directors. These three individuals are not young and inexperienced professionals, but rather seasoned Dermatology experts with over 20 years of experience each, each responsible for different areas of expertise:

• Dean Li Shengtian – Graduated from the College of Food Science at Hanyang University, and holds a professional qualification as a food scientist from the same college at Seoul National University. He has also worked as a food scientist at an Antarctic research station, making him a person with extremely valuable experience in this field.
• Director Zhang Huizhen – with 22 years of experience, she has served as the director of several renowned Dermatology departments and specializes in injectable treatments and skin management.
• Dean Liu Zhangshi ——a graduate of the College of Food Science at Hanyang University, he previously served as a visiting professor at the Baijiu Research Institute and has extensive expertise in anti-aging treatments such as INMODE, Thermage, and thread lifting.

For a foreigner like me who is visiting for the first time, the greatest advantage of the system with three directors is that during the consultation, you won’t feel pressured into making any purchases. The experts will provide very objective suggestions based on your skin type and needs.

Main services and prices at DIar Dermatology: It’s actually much cheaper than having the procedure done in Taiwan.

DIar’s range of services is very extensive, covering everything from anti-aging and lifting treatments to skin care, injectable fillers, and body sculpting. Below are the price ranges for its main services in 2026, all listed in Korean won:

If we only consider Thermage FLX, the price in South Korea is approximately 60-70% of the price in Taiwan. Additionally, since there are fewer options available for INMODE body sculpting in Taiwan and the prices are relatively higher, opting for this treatment in South Korea is particularly cost-effective. For those who wish to undergo procedures on multiple areas at once, the difference in cost becomes even more significant.

What makes INMODE radiofrequency body sculpting different from other methods?

INMODE is one of DIAR’s flagship treatments. It utilizes high-frequency radiofrequency technology to simultaneously achieve both “Lifting” and “destruction of fat cells.” Unlike traditional HIFU devices, INMODE does not require anesthesia, and the recovery time is much shorter – you can go shopping right after the treatment.

There are several aspects of DIAR’s INMODE that make me feel quite reassured: first, the director conducts a detailed assessment of the fat layer; second, the equipment is officially certified by the manufacturer; third, the prices are transparent, with no additional charges during the process. Among similar INMODE clinics in the Gangnam area, DIAR’s director has one of the most impressive backgrounds in this field.

What is the experience like for foreigners to receive medical treatment at diar? Is there any language barrier?

To be honest, what worries me the most is the language issue. DIar provides Chinese-speaking consultants for assistance, and translation apps can also be used during in-person consultations. Additionally, when making an appointment through BeautsGO, you can fill out the form in Chinese directly; upon arrival at the clinic, just present the confirmation email, which is very convenient.

The consultation process generally follows these steps: fill out a form → be guided by a Chinese staff member → have a face-to-face consultation with the director → finalize the treatment plan → undergo the procedure on the same day or the next day. The entire process takes approximately 40 minutes to 1 hour. It is recommended to go on weekdays, as there are usually more people on weekends.

Common Issues in Dermatology at DIar diar

Q1: Can I use a credit card at DIar Dermatology?

Sure. International credit cards such as Visa and Mastercard are accepted, as well as UnionPay. Basically, all clinics in South Korea that offer cosmetic treatments accept card payments.

Q2: Do foreigners need a passport to visit diar?

You must bring your passport during the in-person consultation. For certain treatments (such as injections), it may be necessary to provide information for foreign visitors.

Q3: Is INMODE of DIar the same as what is used in Taiwan?

The equipment is also INMODE original brand, but the doctors in South Korea have more experience operating INMODE devices (after all, this technology has been well-established in South Korea), and the prices are usually 30-50% cheaper than those in Taiwan.

Q4: How to choose between Thermage FLX and Oligio?

If you have a generous budget, consider FLX (5th generation, with longer-lasting results); if your budget is limited or this is your first time trying this type of treatment, Oligio is a good option (a local South Korean brand that causes less discomfort and costs approximately one-third of the price of FLX).

Q5: Is it cost-effective to fly from Taiwan to Seoul for cosmetic surgery?

If you undergo more than two treatments (such as Thermage + hyaluronic acid injections), and include the costs of airfare and accommodation, the total cost is usually lower than if you had the treatments in Taiwan. However, if you only choose one treatment, the difference in cost is not significant.

Q6: Does DIar Dermatology offer Chinese-language services?

We have Chinese-speaking consultants who can assist with translation during in-person consultations. You can also make appointments in Chinese through the BeautsGO APP.

Q7: How long does it take to see the results after undergoing INMODE treatment?

You will immediately notice that your skin has become firmer, while changes in the fat areas usually become apparent after 2 to 4 weeks. It is recommended to have a follow-up assessment after 3 to 6 months.

Q8: What are the advantages of DIar compared to other Dermatology clinics in Gangnam?

The greatest advantage of these three directors is their combined experience of over 20 years, which is quite rare in the Gangnam area. In addition, they are equipped with top-tier facilities such as INMODE, Thermage FLX, and HIFU, eliminating the need to travel between different clinics.
