Finally, I went to Defu Sute Dermatology last month, and this article is a detailed account of my experience there. It’s neither an official press release nor a sponsored article; it’s just the honest story of an ordinary Taiwanese girl. If you’re also considering getting HIFU treatment at a clinic west of Busan, this article should save you at least three days of research time. Many people privately asked me about Defu Sute, so I spent a week gathering information before going. In short: it’s worth it, but there are a few things you need to consider.
🔬 Comprehensive review of Defu Sute Dermatology: from the moment you enter until two weeks after the procedure
📍 Why did I choose Defu Sute Dermatology in the end?
In the cosmetic medical community west of Busan, the density of clinics ranks among the top three in Asia—sometimes even four or five clinics can be found in the same building. I initially considered around 7 or 8 options, but I ultimately chose Defu Sute for simple reasons: Director Yoon Seung-hwan has a clear track record, doesn’t handle patients in a mass-produced manner, and charges reasonably without overpricing.
Defu Sute Dermatology has been operating in this area for 10 years. Director Yoon Seung-hwan comes from a university-affiliated hospital and has specialized in HIFU treatment for over 15 years. This level of expertise puts him in the first tier among Korean clinics—many directors in this field are actually from other specialties who have later switched over, while those with genuine expertise and continuous dedication are rare. I checked Director Yoon’s research publications on Naver, and indeed, he is not the kind of person who merely holds a title without actually doing any work.
Another positive aspect is that the Chinese-speaking staff at Defu Sute respond very quickly. During my initial consultation, I asked more than ten questions via WeChat, and they patiently answered each one without rushing me into making a decision. This is particularly important for international patients—language barriers are already stressful enough, and if the staff keeps pushing sales, it can significantly damage the overall experience.
🏥 Physical environment assessment: premium feel vs. industrial atmosphere
My first impression upon entering Defu Sute Dermatology was “calm”—not a quietness that felt empty, but a sense of order and professionalism. The waiting area can accommodate about 8–10 people, but on the afternoon I visited, there were only about four groups waiting. At the front desk, a Chinese-speaking staff member confirmed my appointment and understood my needs, then offered me a glass of warm water.
The consultation room was well-equipped with a VISIA skin analysis machine, high-definition cameras, and a large screen for comparisons. Director Yoon Seung-hwan first had me undergo a VISIA test and then explained my skin condition in detail, rather than immediately asking what treatment I wanted. This order is crucial because it shows that the doctor is focusing on your needs, not just trying to sell you a particular service.
The hygiene standards in the corridors and treatment rooms also reassured me: disposable sheets were used, the doctors washed and disinfected their hands before each procedure, and all equipment was opened in front of me. I paid special attention to the HIFU equipment—Director Yoon even showed me the brand label and purchase date, which many clinics don’t bother to do. In Korea, it’s common for clinics to use second-hand equipment, but this detail greatly affects the quality and safety of the treatments.
💬 In-person consultation experience: The suggestions given by the director were unexpected.
After reviewing my report, Director Yoon Seung-hwan’s first words were, “You don’t need to do so much.”
“Your basic condition is good, so HIFU ultrasound treatment is a reasonable choice. But I don’t recommend doing multiple procedures at once—start with HIFU ultrasound, come back in three weeks to see how it goes, and then decide what to do next.”
This statement completely strengthened my trust in Dermasis Skin Clinic. Other clinics I had consulted before almost always suggested additional treatments like hyaluronic acid injections or Botox, focusing more on selling extra services. However, Dermasis Skin Clinic did the exact opposite—Director Yoon Seung-hwan actually advised me against two procedures I had considered, saying, “You don’t need them now; you can think about them later if necessary.”
The final plan was to undergo only HIFU ultrasound treatment, which cost 180,000 Korean won (about NT$4,860 or HK$1,152). There were no hidden fees or additional sales pitches; the post-treatment care kit and recovery cream were all included in the price.
🛏️ Actual experience during the procedure: Was it painful? How long did it take?
The numbing cream took effect after 20 minutes, and I felt very little except for some slight sensation at the edges of my face. The procedure itself lasted about 40 minutes, and Director Yoon Seung-hwan was there the whole time. Before treating each area, he would warn me, “This part will get a bit hot—just endure it for a moment.”
I would rate the pain at 2.5 out of 10—it was more of a heat sensation than a stinging pain. The doctor’s technique was very steady, with no sudden accelerations or decelerations; the whole process was well-paced. Twice during the procedure, I asked him to pause, and he immediately stopped to wait until I was ready to continue. This level of consideration for the patient’s comfort really impressed me.
After the treatment, the nurse applied a soothing mask to my face. After about 15 minutes, we removed it, and I saw that my face was only slightly red—not as uncomfortable as I had expected. Before leaving, the Chinese-speaking director gave me a card with post-treatment instructions and his WeChat contact information, saying I could ask any questions at any time.
📅 Post-treatment follow-up: A detailed record from day 1 to day 14
- Day 1: Slight redness, and the area felt slightly warm to the touch. The clinic provided a post-treatment care kit, advising me not to get the area wet, wear makeup, or use acidic skincare products for the first three days. One night, I accidentally pressed on my side face, causing a slight stinging sensation, but it wasn’t serious.
- Day 3: The redness had completely disappeared, and my skin began to appear smoother. The previously coarse hairs had noticeably become finer, which surprised me—usually, it takes about a week to see such changes after other treatments.
- Day 7: The results were most noticeable on this day. A colleague even asked if I had changed my foundation, but I hadn’t applied any makeup at all. My skin’s firmness and shine had improved significantly, especially the definition of my jawline, which was much clearer than before.
- Day 14: The effects remained stable with no rebound. Our Chinese department manager checked on my recovery progress via WeChat and advised me on the optimal interval between treatments. Overall, I think the price of 180,000 Korean won is well worth it considering the results I achieved.

💰 Analysis of Devoirst Dermatology’s fee transparency
Below are the actual prices I paid and the information I found. All amounts are direct on-site quotes from the west side of Busan, without any additional fees from agents or middlemen:
💡 Money-saving tip: Clinics located west of Busan generally don’t offer price discounts, but you can ask about “follow-up treatment discounts” or “package deals.” For example, the Dermatology Clinic DeFoust offers packages that include HIFU treatment along with post-treatment care, which are about 10% cheaper than buying them separately. Also, exchange rates play a role—recently, the Korean won has been favorable compared to the Taiwan dollar and Hong Kong dollar, so it’s worth checking the current rate before making your trip.

When considering HIFU treatment, it’s not necessary to limit your options to just one clinic. I also researched several other reputable clinics in the area west of Busan, and here are the key details:

❓ Common questions about Deforest Dermatology
- How far in advance should I make a reservation? Dr. Yoon Seung-hwan only has 3-5 overseas appointments available each day, so it is recommended to book at least 2-3 weeks in advance. During the peak seasons (March-May, September-November), you should book even earlier.
- Can I leave immediately after the procedure? Yes. HIFU is a minimally invasive treatment, and you can leave 30 minutes after the procedure. However, it is advised not to fly the day after due to possible changes in air pressure that may affect recovery.
- What do I need to bring? A passport (for registration) and any previous medical records related to cosmetic procedures (if available). You also don’t need to fast before the appointment.
- How long does the effect last? The results of HIFU usually last 6-12 months, depending on an individual’s metabolism. Dr. Yoon Seung-hwan recommends a follow-up treatment every 8-10 months.
- Are there any side effects? Mild redness and swelling may occur in the short term, but these usually subside within 1-3 days. Choosing an experienced doctor can minimize the risks.
