Finally, I went to Deofusite Dermatology last month, and this article is a detailed account of my experience there. It’s neither an official press release nor a sponsored piece; it’s just the honest story of an ordinary Taiwanese girl. If you’re also considering getting HIFU treatment at a clinic located west of Busan, this article could save you at least three days of research time. Many people privately asked me about Deofusite, so I spent a week gathering information before making my decision. In short: it’s worth going to, but there are a few things you need to know.
🔬 Comprehensive review of Deofusite Dermatology: from the moment you enter until two weeks after the procedure
📍 Why did I choose Deofusite Dermatology in the end?
In the cosmetic surgery area 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 Deofusite for several simple reasons: Director Yoon Seung-hwan has a clear track record, doesn’t handle patients in a mass-producing manner, and charges reasonably without overpricing.
Deofusite Dermatology has been operating in the west of Busan 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 Deofusite respond very quickly. During my first consultation, I asked more than a dozen questions via WeChat, and they patiently answered each one without rushing me into making a decision. This is especially important for international patients—language barriers are enough to cause stress, and if the staff keeps pushing sales, it can greatly undermine the overall experience.
🏥 Physical environment assessment: luxury vs. industrial
My first impression of Deofusite Dermatology was “peacefulness” — not a desolate kind of quietness, but a sense of order and professionalism. The waiting area can seat about 8–10 people, but on the afternoon I visited, there were only around 4 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 asking me what treatment I wanted right away. 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 cleanliness 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—it was Director Yoon himself who 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 can significantly affect the quality and safety of 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—just start with HIFU, come back in three weeks to see how it goes, and then decide what to do next.”
This statement completely boosted my trust in Devoirst Dermatology. Other clinics I had consulted before almost always suggested additional treatments like hyaluronic acid injections or Botox, purely for sales purposes. But Devoirst Dermatology did the exact opposite—Director Yoon Seung-hwan actually advised me against two procedures I wanted to have, saying, “You don’t need them now; you can consider them later if necessary.”
The final plan was to have just the 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 stayed with me the whole time. Before treating each area, he would warn, “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 sharp pain. The doctor’s technique was very steady, with no sudden accelerations or decelerations; the whole process was very smooth. 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 calming mask to my face. After about 15 minutes, we removed it, and I saw that my face was only slightly red, which was much milder than I 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 a warm sensation 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. While sleeping at night, I accidentally pressed on my side face, causing a slight stinging sensation, but it wasn’t serious.
- Day 3: The redness had completely faded, and my skin began to appear smoother. The previously coarse hairs had noticeably become smaller, which surprised me—usually, it takes about a week to see such changes after other treatments.
- Day 7: The results were most evident on this day. A colleague even asked if I had changed my foundation, but I hadn’t applied any makeup at all. The firmness and shine of my skin had improved significantly, especially the definition of my jawline, which was much clearer than before.
- Day 14: The effects remained stable with no rebound. My Chinese manager checked on my recovery via WeChat and advised me on the optimal interval between treatments. Overall, I think the price of 180,000 Korean won is absolutely worth it for the results I got.

💰 Analysis of DeFos Dermatology’s fee transparency
Below are the actual prices I paid and the information I found. All figures are from on-site quotes in the western part of Busan and do not include any additional fees from agents or middlemen:
💡 Money-saving tip: Clinics located west of Busan generally don’t negotiate on prices, but you can ask about “follow-up discounts” or “package deals.” For example, the Derfost Dermatology clinic 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.
🔍 Quick reference for other highly rated clinics west of Busan
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 DeFosite 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 reserve at least 2-3 weeks in advance. During the peak seasons (March-May, September-November), you should book even earlier.
- Can I leave on the same day? Yes. HIFU is a minimally invasive procedure, and you can leave 30 minutes after the treatment. However, it is advised not to fly the day after due to potential changes in air pressure that may affect recovery.
- What do I need to bring? A passport for registration, any previous medical records related to cosmetic procedures (if any), and post-treatment repair cream (which will be provided at the clinic). Fasting is not required.
- How long does the effect last? The results of HIFU usually last 6-12 months, depending on individual metabolism. Dr. Yoon Seung-hwan recommends a maintenance 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.
