Let me tell you, I’m the kind of person who closes my eyes even when getting an injection; my pain receptors are three times more sensitive than anyone else’s. Originally, getting the Ulthrea treatment was far down on my list of things to do in life—until a friend came back from South Korea with a significantly smaller face. When I asked her if she had lost weight, she said, “No, I just went to the Diar Dermatology clinic.”
Okay, inspired by this statement, I flew to Seoul next month and made an appointment there. In this article, I will share my actual experience using the Ulthrea at Gangnam diar Dermatology, as well as why the team of doctors at this clinic managed to put me at ease—even though I am usually very afraid of pain.
I. Why choose DIAR? Practical experiences with the Ulthrea from Gangnam DIAR Dermatology
The Ulthrea, also known as the American version of the HIFU device, uses high-intensity focused ultrasound to target the SMAS fascia layer deep within the skin, thereby stimulating the production of new Collagen. The results are indeed impressive, but the pain associated with this treatment is also quite severe—this is probably the main reason why many people are hesitant to try it.
The approach adopted by DIar Dermatology is quite clever: they first apply topical anesthetic ointment for 30 minutes, and then use a “gradual increase in energy” during the treatment—instead of applying full power all at once, they start with low levels to allow the skin to adapt, gradually increasing the intensity after each treatment area. When I actually lay down for the procedure, the expected sensation of being “pounded relentlessly by an eraser” lasted for less than a third of the total treatment time; in fact, I even started to feel drowsy afterwards.
Moreover, the director in charge of the procedure for me, Dr. Zhang Huizhen, has 22 years of experience. Her hands are extremely steady, and every injection is precisely placed where it needs to be, so there is no uncomfortable burning sensation caused by “energy being wasted on the surface of the skin.” I believe this is the biggest difference between a highly experienced director and an ordinary practitioner.

III. Prices of the Ulthrea HIFU in Dermatology at DIAR in South Korea in 2026
In South Korea, clinic prices are usually determined only after a face-to-face consultation, as everyone’s facial structure, degree of skin laxity, and the number of hairs to be treated vary. DIAR Dermatology uses genuine Ultherapy equipment, not any unknown knockoff models – so you can rest assured on this point.
However, based on my experience in providing on-site consultations, the Ulthrea models offered by DIar generally fall into the following categories:
| Type of Solution | Suitable for various groups | Reference price range |
|---|---|---|
| The lower half of the face (300 hairs) | The jawline is loose, and the Double Chin is very noticeable. | Starting from ¥800,000 to ¥1.2 million |
| Full face (500 hairs) | A more firm entire face and improved Nasolabial Fold Correction | Starting from ¥13 million to ¥1.8 million |
| Full face + neck (800 hairs) | Significant sagging of the face and neck, signs of aging in the skin | Starting from ¥20 million to ¥2.6 million |
The above prices are for reference only; the final amount will be determined based on the doctor’s recommendations after a face-to-face consultation. It is recommended to check BeautsGO first for the latest discounts, as there may sometimes be exclusive offers for overseas customers.
IV. The unique strengths of these three hospital directors: With a combined experience of 74 years, how is the workload distributed among them?
What really reassures me about DIar Dermatology is that the clinic is operated on a rotating basis by three senior directors. It’s not the kind of establishment where there is only one nominal director while the rest are part-time doctors. All three directors have over 20 years of experience in total, which amounts to more than 74 years of combined expertise – a truly rare combination in the highly competitive Gangnam area.
Director Zhang Huijin (장혜진, with 22 years and 4 months of experience)
She graduated from the medical school of the Catholic University of Bolivia and worked as a Dermatology specialist at the Japanese University Hospital in Bolivia. Later, she returned to South Korea and founded the Renueva Skincare Clinic and 리쥬바클리닉. Her areas of expertise include anti-aging treatments and Collagen regeneration therapies, with the Ulthrea being one of her signature services. It was she who performed the procedure on me that day, and her technique was truly meticulous.
President Lee Seong-cheon (이성천, with 26 years and 2 months of experience)
He graduated from the Department of Medicine at HanYang University and completed his postgraduate studies at Seoul National University. He also served as a medical doctor on the wintering team at the King Sejong Station in Antarctica – when I first saw this information, I was truly taken aback. Currently, he is a member of the National Medical Knowledge Improvement Committee of the Korean Medical Doctors Association. He specializes in comprehensive facial contour assessment and the planning of multi-step treatment programs.
Dean Liu Zhangshuo (Yu Jang-seok, with 26 years and 2 months of experience)
Also graduated from the Medical Department of Hanyang University, he once served as a specialist physician and visiting professor at Baik Hospital. Later, he successively held the positions of managing director at Misodream Dermatology and NYU Dermatology, as well as director of the Dermatology Department at Wonjin Plastic Surgery Hospital. His expertise lies in Thread Lifting and body contouring procedures, and he also has extensive knowledge of DIAR’s exclusive Private CELL anti-aging technology.
Each of the three directors has their own areas of expertise: Director Zhang specializes in HIFU and Collagen treatments, Director Li is skilled in comprehensive assessments, while Director Liu focuses on thread lifting and body contouring procedures. No matter which type of lifting treatment you are interested in, you will definitely find a senior director who specializes in that area.
V. What is the environment like at Gangnam diar Dermatology in South Korea?
The DIar Dermatology clinic is located on the 10th floor of the KI Tower. As soon as the elevator doors open, you are greeted by a bright and spacious lobby, completely different from the dim and cramped atmospheres of some other clinics. The waiting area is comfortable, and there are separate consultation rooms, so patients don’t have to wait in crowded areas with other clients. The equipment in the treatment rooms looks brand new – the surgical lights and Ultherapy devices are neatly arranged in their respective areas, which is definitely a plus.
The official website has a dedicated SPACE page, which is divided into several areas: Reception, Lobby, Relax, and Procedure. There is also a powder room specifically for women, so after the treatment, they can quickly tidy up their appearance before going out – which is really convenient for female customers.
