Last month, I finally made a trip to Secret Dermatology. This article is a detailed record of my experience there. It is neither an official press release nor a brand collaboration piece; it simply reflects the true experiences of an ordinary Taiwanese girl. If you are also considering going to Gangnam, Seoul, to receive Rejuran treatment, this article should help you save at least three days of research time. Many people have privately asked me about Secret Dermatology, so I spent a week gathering information before making the trip. In short: it’s worth going, but there are a few things you need to keep in mind.
🔬 Comprehensive review of secret Dermatology: from the moment you enter the clinic until two weeks after the procedure
📍 Why was secret Dermatology chosen in the end?
In the medical aesthetics industry in Gangnam, Seoul, the density of clinics ranks among the top three in all of Asia; in the same building, there may be four or five clinics. Initially, I considered around 7 or 8 options, but ultimately I chose secret Dermatology for a very simple reason: Director Song Seung-hyun has a clear track record of his work, does not engage in mass treatment, and charges reasonable fees without arbitrary price increases.
Secret Dermatology has been operating in Gangnam, Seoul for 12 years. Director Song Seung-hyun comes from a university-affiliated hospital and has specialized in Rejuran for over 12 years. Such expertise places him among the top professionals in South Korea’s clinic industry – many clinic directors have in fact switched fields, while those who truly have a specialized background and have dedicated themselves to the same field for a long time are relatively rare. I checked Director Song Seung-hyun’s research publications on Naver in South Korea, 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 person in charge of the Chinese-speaking service at secret Dermatology responds very quickly. During my first consultation, I asked more than a dozen questions via WeChat, and they patiently answered each one of them without any pressure to place an order immediately. This is really important for overseas customers – dealing with language barriers is already stressful enough, and if the service provider keeps pushing sales, it can significantly damage the overall experience.
🏥 Actual environmental conditions: A sense of luxury versus an industrial atmosphere
The first impression upon entering secret Dermatology is one of “calmness” – not the kind of quietness that suggests emptiness, but rather a sense of order and professionalism. The waiting area can accommodate around 8 to 10 people, but on the afternoon I visited, there were only 3 customers there. At the reception, a Chinese-speaking manager confirmed my appointment and understood my needs in simple Chinese before offering me a cup of warm water.
The consultation room is equipped with all the necessary facilities: a VISIA skin analysis device, high-definition cameras, and a large-screen monitor for comparison. Director Song Seung-hyun first had me undergo a VISIA examination, and then explained my skin condition item by item – rather than asking me right away, “What treatment would you like to have?” This order is very important because it shows that the doctor is focusing on your needs, rather than the treatments he wants to recommend.
The hygiene standards in the corridors and treatment rooms also reassured me: disposable sheets were used, doctors washed and disinfected their hands before each procedure, and the equipment was opened in front of my eyes. I paid special attention to the equipment at Rejuran – Director Song Seung-hyun even took the time to show me the brand labels and purchase dates of the machines, something that many clinics do not bother to do. In South Korea, there are actually quite a number of clinics that rent used equipment, and such details can directly affect the effectiveness and safety of the treatments.
💬 In-person consultation experience: The suggestions given by the hospital director were completely unexpected.
After reading my report, Director Song Seong-hyun’s first reaction was: “You don’t need to go to such great lengths.”
“Your basic condition is quite good, so Rejuran is a reasonable choice. However, I don’t recommend undergoing multiple treatments at once. First, get the Rejuran treatment, and then come back for a follow-up in three weeks to see the results before deciding on the next step.”
This statement completely strengthened my trust in secret Dermatology. Previously, when I consulted other clinics, they almost always suggested things like “you could try hyaluronic acid treatment again” or “adding botulinum toxin would give better results” – it was pure sales talk. However, secret Dermatology did the exact opposite; Director Song Seung-hyun even actively advised me against two treatments I had considered, saying, “You don’t need them now; you can think about them again if you ever need them in the future.”
The final decision was to undergo the Rejuran treatment alone, at a cost of 250,000 South Korean won (approximately NT$6,750 or HK$1,600). There were no hidden fees or additional sales pitches; both the post-treatment care package and the repair cream were included in the price.
🛏️ Actual experience during the treatment: Is it painful? How long does it take to complete?
The numbing effect lasted for 25 minutes, and the anesthetic had a very complete effect – only the edges of the face were slightly sensitive to touch. The entire procedure took approximately 30 minutes, and Director Song Chengxuan was present throughout the whole process. Before treating each area, he would always remind the patient, “This area will feel a bit hot; please endure it for a moment.”
I would rate the pain level at 3.5 out of 10 – it was more of a burning sensation than a stinging pain. During the procedure, I could feel that the doctor’s technique was very steady, with no sudden accelerations or decelerations; the rhythm was consistently maintained. On two occasions, I raised my hand to indicate that I needed a pause, and Director Song Chengxuan immediately stopped and waited until I was ready to continue. Such respect for the patient’s comfort is truly commendable.
After the procedure, the nurse applied a calming facial mask to me. About 15 minutes later, she removed it, and when I looked in the mirror, I noticed only slight redness—much milder than I had expected. Before leaving, the Chinese-speaking supervisor gave me a card with post-treatment instructions and her WeChat contact information, saying I could ask her any questions at any time if there were any issues.
📅 Post-treatment follow-up: A complete 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, instructing me not to get the area wet, not to wear makeup, and not to use any skincare products containing acids in the first three days. At night, I accidentally pressed on my side face while sleeping, causing a slight stinging sensation, but it wasn’t serious.
- Day 3: The redness had completely subsided, and the skin began to become smoother. The previously thick hairs had noticeably become smaller, and I was quite surprised by this speed – usually, it took about a week to see any changes after undergoing other treatments.
- Day 7: The day when the effects were most noticeable. A colleague asked me if I had changed my foundation – but in fact, I hadn’t applied any makeup at all. The firmness and glow of my skin had improved significantly, especially the definition of my jawline, which was much clearer than before.
- Day 14: The results remained stable, with no rebound at all. The person in charge of the Chinese-speaking group kept tracking my recovery progress on WeChat and reminded me of the optimal interval between treatments if I decided to have a second session. Overall, I think the results achieved for the price of 250,000 Korean won are definitely worth it.

💰 Analysis of the transparency of fees at secret Dermatology
The following are the actual prices I paid and the information I obtained. All these quotes are from local providers in Gangnam, Seoul, and do not include any additional fees charged by agents or middlemen.
💡 Money-saving tips: Clinics in Gangnam, Seoul generally do not accept price discounts, but you can ask about “follow-up treatment discounts” or “package deals”. Secret Dermatology, for example, offers packages that include Rejuran treatment along with post-treatment care, which are approximately 10% cheaper than purchasing these services separately. Additionally, the exchange rate is also an important factor – recently, the Korean won has been favorable compared to the Taiwanese dollar and Hong Kong dollar. It is recommended to check the current exchange rate before making your trip.

❓ Frequently Asked Questions about Secret Dermatology
- How far in advance should one make a reservation? Director Song Chengxuan only has 3 to 5 available spots for overseas patients each day, so it is recommended to reserve at least 2 to 3 weeks in advance. During the peak seasons (March to May, September to November), it is even necessary to book even earlier.
- Can I leave on the same day after the treatment? Yes. Rejuran is a minimally invasive treatment, and you can leave 30 minutes after the procedure. However, it is recommended not to take a flight the next day, as changes in air pressure may affect the recovery process.

- How long does the effect last? The effects of Rejuran usually last for 6 to 12 months, depending on an individual’s metabolic rate. Director Song Seung-hyun recommends a maintenance treatment every 8 to 10 months.
- Are there any side effects? In the short term, mild redness and swelling may occur, but these usually subside within 1 to 3 days. Choosing a experienced doctor to perform the procedure can minimize the risks.
