The Dcard sisters didn’t lie to me! Reviews of ON Clinic | I personally tested Dr. Kim Yong-hyun’s linear lifting treatment, and it worked 3 days faster than the anti-swelling treatments in Taiwan – and there was no stiffness at all.

🎯 Why did I go to South Korea for linear lifting instead of staying in Taiwan?

“Quick swelling reduction, no stiffness, and the results are so natural that my colleagues think I just lost weight” – This statement is not something I made up out of thin air; it is the common conclusion drawn from at least twenty reviews on the South Korea version of the Dcard platform. I personally took a trip to Seoul and had linear lifting procedures performed by Director Kim Yong-hyun. Now, I can tell you with certainty: it’s true.

Let me state the conclusion first: The swelling subsided much faster than after the HIFU treatment I had in Taipei – it was already completely invisible by the fourth day. Moreover, the contours of my face looked so natural that my mother even asked me, “Are you losing weight recently?” There was absolutely no noticeable “pulling-up” effect of the skin, which sometimes happens after unsuccessful facelift surgeries. Director Jin truly has unique skills. Below, I will share in detail my experience, the cost, and how to make an appointment.

📋 Introduction to ON Clinic and Dr. Kim Yong-hyun

ON Clinic, located in Gangnam District, Seoul, is one of the Dermatology clinics that has received considerable attention from Taiwanese people in recent years. Unlike those chain clinics that blindly pursue fame, ON has a clear focus: it relies on the expertise and reputation of its director to attract patients, rather than investing heavily in location or decoration.

President Kim Yong-hyun is the representative director of ON Clinic, specializing in anti-aging Lifting treatments and injectable procedures. He is best known for three things: First, his precise control over the injection angle and layering technique in linear lifting procedures, allowing him to customize suspension strategies based on each individual’s bone structure; second, the remarkably fast results in reducing swelling—many Taiwanese clients have reported being able to go out shopping the very next day after treatment; third, his high level of price transparency, as he provides clear quotes during consultations without any subsequent price increases.

President Kim has over 12 years of clinical experience in the field of Dermatology in South Korea. He previously served as the chief executive of a large cosmetic surgery institution in Seoul before founding ON Clinic independently. His philosophy is that “Lifting does not involve pulling; rather, it is about returning the face to its natural position.” These exact words were spoken by him during a consultation, and I believe they accurately capture the essence of his approach.

🧠 What is linear lifting? How is it different from HIFU and Thermage?

Many people often confuse linear lifting with HIFU (Ultherapy / 초음파칼) or Thermage (Thermage / 올리고), but in fact, they are completely different technologies.

• HIFU: Utilizes ultrasonic energy to heat the fascia layer, thereby promoting the production of new Collagen. The effects are “gradual”; it takes approximately 2–3 months to see the best results after treatment.
• Thermage: Uses radiofrequency energy to heat the dermis, thereby tightening the skin; this too produces gradual results.
• Linear lifting: Absorbable protein threads (PDO/PLLA) are implanted into the subcutaneous fat layer, physically lifting the sagging tissues back into place. The results are visible immediately.

In simple terms, HIFU and Thermage work by “using the Collagen that your body naturally produces to support your facial structure,” while linear lifting uses threads to directly lift the skin. The two methods can complement each other, but if you want to see immediate results, linear lifting is more direct.

If you want to learn more about projects related to the HIFU, you can refer to this review and test report on the Jiangnam barog device. It mentions the concept of ligament reinforcement, which shares some similarities with the principle of linear lifting procedures.

💯 My personal experience and full record of using linear lifting treatments

Step 1: Online consultation and pre-operative communication

I underwent a pre-operative consultation through WeChat via s-sourire. I sent over photos of my side profile and the areas I wanted to improve (Nasolabial Fold Correction, jawline), and approximately two hours later, I received a response containing Dr. Kim’s preliminary suggestions and quotes. The entire communication was conducted in Chinese, so there were no language barriers at all. Moreover, s-sourire helped me confirm Dr. Kim’s schedule and find a suitable time for me.

This is really extremely important – many Taiwanese people who go to South Korea for cosmetic procedures for the first time are most worried about not being able to communicate and ending up being treated as mere objects. With the help of s-sourire, someone will take care of everything from the consultation to the follow-up after the procedure; all I had to do during my entire trip was simply “show up for the appointment and lie down for the treatment”.

Step 2: Arrive at the clinic for a pre-operative assessment

ON Clinic is located in Gangnam District, just a 5-minute walk from Sinnyeonhyeon Station on Line 9 of the subway. The exterior of the clinic is not particularly luxurious, but the interior is clean and tidy. A Chinese-speaking staff member was already waiting for me at the reception desk.

President Kim personally helped me with the consultation. He used a dermatoscope to examine my skin type and then marked the injection points on my face. The key point was that he didn’t simply “pull everything together” without considering the asymmetry between my left and right sides of the face; instead, he devised different suspension techniques based on those differences. He explained to me, “The Nasolabial Fold Correction on your left side is 2 mm deeper than on your right side, so I need to use an additional thread on the left side and adjust the angle slightly upward.” Such precision really reassured me.

Step 3: The surgical procedure (approximately 40 minutes)

The procedure began approximately 30 minutes after the anesthetic was applied. Dean Jin’s movements were very precise; there was almost no pain during the injection—the anesthetic had been applied thoroughly. After inserting each thread, he would slightly adjust the angle and then use his fingers to confirm the extent of the Lifting. Throughout the process, I could feel my face being “lifted upward,” but it didn’t hurt at all.

The procedure took about 40 minutes. Director Kim used a mirror to show me the results. My first reaction was: “Wow, the Nasolabial Fold Correction is really much less noticeable now, and the line of my jaw is also clearer.” But he told me quite honestly, “It’s still swollen right now; the effect will look more natural after the swelling subsides, which should take about three to five days.”

Step 4: Postoperative recovery and follow-up

On the day of the treatment, my face was noticeably swollen, but it wasn’t the kind of swelling that would cause my whole face to become distorted; it was more like a mild swelling. By the next day, the swelling had reduced by 70%, and by the fourth day, it had almost completely gone away. Compared with the HIFU treatment I had in Taipei, the swelling subsided three days faster this time (after the Taipei treatment, my face was swollen for a whole week).

Regarding the post-operative precautions, Director Kim explained them very clearly: avoid strenuous exercise in the first three days, do not massage or stretch the affected areas, and use a higher pillow when sleeping. On the first and third days after the surgery, s-sourire took the initiative to check on my recovery progress and even sent me a graphic tutorial with a schedule for applying ice packs, which was really thoughtful of them.

💰 Price reference for ON Clinic’s linear lifting treatment

The following are the actual prices I consulted (as of May 2026, the exchange rate was approximately 1 Korean won = 0.024 Taiwanese dollars):

This price is considered moderately low in the Gangnam area, and it is much cheaper than similar services offered by barog or Theia in the same region. If you are planning to undergo treatments such as hyaluronic acid injections or maintenance therapies, it is recommended to opt for packages that include meals, as this will provide better value for your money. For comparison, you can refer to Theia’s medical beauty price list and the reviews of Renovo Skin Clinic.

✅ ON Clinic vs Taiwanese cosmetic surgery: Why did I choose South Korea?

To be honest, there are quite a number of clinics in South Korea that offer linear lifting treatments, and the prices might even be lower (in some Taiwanese clinics, 10 threads can cost just over NT$20,000). However, there were three main reasons why I ultimately chose South Korea:

1. Technical expertise of the clinic director: The market competition in linear lifting treatments in South Korea is extremely fierce, and only experienced doctors who have performed thousands of such procedures are able to survive in this environment. Director Kim may perform more linear lifting treatments in a year than what an average clinic in Taiwan manages to do in three years. The precision achieved through such extensive experience cannot be compensated for by price alone.
2. Quality and selection of threads: South Korea’s clinics offer a much wider range of thread brands and types than those available in Taiwan. When consulting with Dr. Kim, he presented me with at least five different types of threads in various materials and thicknesses to choose from, and then recommended the most suitable combination based on my skin type and needs. In contrast, many clinics in Taiwan only offer one or two types of threads for customers to choose from.
3. Reduction in swelling speed: This is what concerns me the most. Director Kim’s technique of inserting needles significantly reduces the time required for swelling to subside, which is particularly important for working professionals who have limited time off from work. On the fourth day after my treatment in South Korea, I was already able to go out shopping without any problems at all.

Of course, if you don’t want to fly to South Korea, there are also great options in Taiwan. But if you have already planned to travel to South Korea and take the opportunity to undergo a linear facelift procedure, that would definitely be the best option in terms of cost-effectiveness.

📝 Summary: Is the Linear Lifting treatment offered by Dr. Kim at ON Clinic really worth it?

After conducting a full month of follow-up observations, my conclusion is: it is absolutely worth it. The results of the linear lifting procedure are most noticeable two weeks after the surgery; even now (one month after the surgery), the facial contours remain well-defined, and the Nasolabial Fold Correction has faded by at least 60% compared to before the surgery.

If you meet the following requirements, I would recommend that you consider Dr. Kim Yong-hyun’s Linear Lifting treatment at ON Clinic:

• If the Nasolabial Fold Correction or the sagging of the jawline is noticeable, and you want to see results immediately
• I hope for quick swelling reduction and a short recovery period (suitable for working professionals or travelers with limited time).
• The budget ranges from NT$30,000 to NT$60,000 (depending on the number of SISUNs required).
• Emphasis is placed on the personal skills and experience of the clinic director; there is no focus on the decoration of the clinic itself.
