Previously, a close friend recommended THE FIRST DERMATOLOGY CLINIC in Busan to me, saying that the director was very professional and had plenty of time for in-person consultations – nothing like the typical situation where patients wait in line for two hours just to get three minutes of attention. With some skepticism, I decided to give it a try, and… I was truly impressed. In this article, I will explain Director Oh Ji-soo’s background, her approach to patient care, as well as the in-person consultation system that I witnessed firsthand.
Who is Director Xu Zhixiu? Take a look at her professional background in one go.
Dr. Xu Zhixiu is the chief physician at the Busan Debeost branch. Five other specialist doctors also assist in the diagnosis and treatment process. Dr. Xu adheres to a personal consultation model – from the initial assessment to the actual treatment, everything is supervised by her personally, without any assistance from assistants or interns. This approach is relatively rare in the Busan area; many larger clinics, due to the high volume of patients, only have the chief physician conduct assessments, while the actual treatments are often performed by other doctors.

Before making the appointment, I had checked the information on BeautsGO. The page for DeFoster in Busan provided a detailed introduction to the director and his years of experience. This time, I booked an HIFU treatment. From the pre-treatment consultation to the actual procedure, Director Xu personally explained the exact location of each HIFU beam – rather than having the nurse perform the treatment while the doctor just observed from a distance.
The actual experience of the in-person consultation system: Is it really like what people say?
To be honest, at first I was also afraid of that kind of “excessive marketing” – where the clinic director is portrayed in an overly positive light, only to discover upon actual visit that things were completely different. However, at DeFoster Clinic in Busan, they truly practice what they preach. On that day, I underwent the second-generation Ulthrea treatment (600 shots). Starting from the pre-treatment assessment, Director Xu used a skin analysis device to identify my problem areas in detail and explained the specific treatment approaches for my Forehead, Nasolabial Fold Correction, and Double Chin.

During the treatment, the clinic director would explain while injecting, saying things like “We’re injecting here to tighten the contours” or “This area is a bit deeper; you’ll need to endure it for a moment.” Instead of just finishing the procedure without any explanation, this approach created a sense of genuine attention and care, which was clearly different from the impersonal, assembly-line-like experience at chain clinics.
What is the difference between when the director performs the procedure himself and when an assistant does it?
A question that many women are concerned about is: “When it comes to so-called in-person consultations, does it mean that I will only meet the director during the assessment, while someone else actually performs the treatment?” At Debeost in Busan, this is not the case. Based on my observations as well as the information provided on the BeautsGO website, Director Xu Zhixiu personally operates the HIFU equipment throughout the entire treatment process, while the nurses are solely responsible for pre- and post-treatment cleaning and supportive care.

The depth of application and the distribution of HIFU shots require great expertise – shallow shots are used to define the contours, while deeper shots target the SMAS fascia layer. Even a slight deviation in position can significantly affect the results. This is where the value of having the director personally perform the treatment lies: the location of each shot is determined on-site based on the shape of your face, rather than following any pre-set template.
Suitable candidates for Dr. Xu
Director Xu Zhixiu’s approach to patient care is meticulous and patient-oriented, making her particularly suitable for the following groups:
The first category includes those who **notice a decline in facial contours**—with loose skin around the face, the downward movement of the Apple Zone, and a blurred jawline. HIFU is currently one of the most effective non-surgical methods for lifting the skin, and Dr. Xu has extensive experience in using this technique. The second category consists of those who **do not want to go through a standardized, efficient treatment process**. If you have previously visited clinics where you have to queue up early in the morning, wait for two hours, and then leave after just five minutes, DeFoster’s personalized consultation system will provide you with a different experience.

The third category is **for foreigners experiencing this service for the first time** – DeFoster in Busan offers Chinese-speaking service windows, so there’s no need to worry about language barriers. During the initial consultation, the director will use translation software along with visual aids to provide explanations, and after the procedure, comprehensive Chinese-language instructions will also be provided.
Records of the actual effects of HIFU (the author is Dr. Xu himself)
On days 1 to 3 after the procedure: The face may show mild redness and a slight sense of soreness when touched, especially at the junction of the lower jawline and the neck. This is a normal reaction and does not require any special treatment.
On the 7th day after the procedure: The swelling had subsided, and I began to notice a slight tightening of my facial contours, although the results were not yet final. At this stage, applying makeup felt more comfortable, as the contours appeared firmer.

30 days after the procedure: At this point, the effects of HIFU begin to reach their peak. The contour lines become approximately 30-40% clearer than before the treatment. The depth of the Nasolabial Fold Correction is reduced, and the position of the Apple Zone appears to rise slightly, giving the person a more refreshed look. There is no need to apply heavy makeup or use concealers when going out.
How to make an appointment with Director Xu Zhixiu
Currently, Director Xu is accepting appointments from foreign patients on the BeautsGO platform. You can simply visit the BeautsGO page for Busan DeFoster and select Dr. Xu Zhixiu to schedule your appointment and choose the treatment you desire. It is recommended to book at least one week in advance, as weekend schedules are usually full.
Another important reminder: When visiting a clinic for the first time, it is recommended to bring along records of any previous cosmetic treatments you have undergone (including the dates and names of the products used). This will help the director assess your current skin condition and the depth of previous treatments more accurately.
