Avoid the pitfalls of excessive technical costs! On-clinic prices at the 2026 Gangnam store: 2.1 million for Phoenix Radio waves and 250,000 for Linear Sound Waves – no hidden fees.

💰 ON Dermatology 2026 Complete Price List: Is Gangnam the best option in terms of cost-performance ratio?

A name that has been frequently discussed in South Korea’s Dermatology forums – ON Skin Clinic / ON Dermatology. Why? Because their pricing logic is completely different from that of most clinics in Gangnam: they don’t charge any “brand premium” fees; instead, they break down the costs into specific individual items, so you can clearly see where each 2.1 million South Korean won goes. Compared to those chain clinics in Myeongdong that routinely add on “anesthesia fees” and “post-treatment management charges”, ON’s pricing system is so transparent that it’s almost unbelievable – why can’t other clinics do the same?

In this article, I have compiled all the latest official prices of ON Aone for 2026. From the signature Ligament Reinforcement procedure performed by Director Kim Yong-hyun himself to Linear Ultherapy, I have listed the price differences between when the procedure is performed by the director and the deputy director, so you can accurately estimate the costs before making an appointment. If you are reading this guide to booking appointments at Gangnam ON Aone Dermatology, this price list is an essential reference for you.

👨‍⚕️ Who is President Kim Yong-hyun? Why are his prices considered trustworthy?

Director Kim Yong-hyun is a key figure at ON Dermatology and is virtually the sole practitioner of all the high-value treatments offered by the clinic. His expertise lies in facial contour restructuring and anti-aging Lifting procedures, among which his most renowned technique is the “Ligament Strengthening Procedure” – a composite lifting method that combines HIFU with linear Lifting techniques, specifically designed to address issues such as facial sagging, deepening of the Nasolabial Fold Correction, and blurred jawlines.

His surgical style is described in South Korea’s medical aesthetics community as “extremely precise, down to the millimeter level.” Patients who have undergone his procedures have shared that Dr. Kim would carefully trace the injection route along the contours of the jawbone before starting the procedure, marking numerous points all over the face – he is certainly not the type of doctor who just starts working after a quick glance. This is also the reason why his appointments are always booked three weeks in advance: it’s not some marketing gimmick, but rather a true reflection of the amount of time and attention his work requires.

The key point is that, within ON Aoen’s pricing system, the price difference between what President Jin and the vice president charge is clearly displayed. Unlike some clinics that uniformly increase prices by 30% under the pretext of “presidential-level services,” ON lists the prices charged by both the president and the vice president for each service in detail, allowing customers to choose according to their budget and needs.

📋 Complete price list for ON Aon Dermatology in 2026

The following prices are compiled based on the official 2026 rates of ON Dermatology. The exchange rate used is approximately 1 Korean won = 0.024 New Taiwan dollars (please verify the actual exchange rate yourself). All prices listed are basic fees and do not include any possible additional charges.

📌 Note: The above prices are official reference figures for early 2026. The actual fees will be determined during the in-person consultation. For major procedures such as ligament reinforcement or Phoenix radiofrequency treatment, additional costs may be incurred depending on individual circumstances. However, what sets ON Awen apart is that the additional fees will be clearly communicated before the procedure, rather than being disclosed only after the treatment is completed.

🔥 In-depth analysis of the featured treatment: Is ligament reinforcement surgery really worth 2.1 million?

Ligament Reinforcement is a technique developed by Director Kim Yong-hyun. It is also ON Oen’s most expensive and most controversial treatment option. At a price of 2.1 million Korean won, it falls into the mid-to-high-end range in Gangnam District – 30% more expensive than regular HIFU treatments, but 40% cheaper than some plastic surgery procedures that claim to be performed by the director personally.

The core concept of this technology is that it does not merely heat the Collagen in the skin (like Thermage does), but instead acts directly on the deep facial ligaments (the SMAS layer). By utilizing HIFU energy to strengthen the structure of these ligaments, the originally loose tissues are tightened again. The effects of this treatment last longer than those of Thermage or HIFU alone, typically ranging from 18 to 24 months in clinical practice.

The entire procedure takes approximately 60 to 90 minutes, and Dr. Kim personally oversees the whole process. Unlike in most clinics where the director only participates in the final 10 minutes of confirmation, Dr. Kim is involved from the initial marking to the actual treatment and the subsequent follow-up checks. This is also the reason why appointments for on treatments must be reserved at least three weeks in advance – each patient takes up too much of Dr. Kim’s time.

If you would like to understand the reservation process and details of the in-person consultation, you can refer to the Gangnam ON Dermatology reservation guide, which provides a detailed record of the entire process, from consultation to post-operative care.

🆚 Price comparison between ON Aon and Gangnam’s similar-level clinics

Just looking at the numbers doesn’t provide an intuitive understanding. I have compiled a comparison of the prices offered by ON Aon and three other popular Dermatology clinics in Gangnam District, so you can easily see which one is more competitive:

It is clear that ON offers lower pricing for HIFU and linear ultrasound treatments compared to the average level in Gangnam District, while its hyaluronic acid injection services fall in the middle range. Overall, if you focus on Lifting treatments, ON offers a particularly excellent cost-performance ratio.

⚠️ Must-read before making a reservation: Three key tips to save money and avoid pitfalls

1. Do not book directly through South Korea’s travel agencies or local discount platforms: Many tourists book their appointments through travel agencies or such platforms in South Korea, only to discover upon arrival that the services are actually provided by interns. For appointments with Dr. Kim Yong-hyun at ON Aone, it is necessary to book through official channels. It is recommended to consult via WeChat at s-sourire to confirm the availability of the desired doctor.

2. Ask clearly about “extra fees” before signing the contract: Although ON is known for its transparency, some treatments (especially complex procedures) may incur additional costs for anesthesia or post-operative ice application management. During the consultation, ask directly: “Does this price include all the relevant fees? Are there any additional charges?”

3. The exchange rate is very important: In early 2026, 2.1 million Korean won were approximately equivalent to NT$50,400, but the value of the Korean won fluctuates significantly. It is recommended to monitor the exchange rate two weeks before your trip; if the Korean won weakens, it would be an ideal time to make your purchase. You can use the BeautsGO platform to check real-time quotes and lock in the exchange rate at which the product is priced in Korean won.

📞 Two ways to make an on appointment with Aon Dermatology

Route A: Connect directly with s-sourire via WeChat. Add s-sourire on WeChat to receive a one-on-one pre-treatment assessment. You can check Dr. Kim Yong-hyun’s schedule in real time and enjoy exclusive internal discounts. s-sourire also provides Chinese translation services, which is very convenient for Taiwanese girls who don’t speak Korean.

Route B: Booking through the BeautsGO platform – Open WeChat, search for “BeautsGO”, enter the mini-program, and then type “ON Clinic” or “ON Dermatology”. You can directly view the schedule of the director and compare prices. The platform offers a certified green channel; after making a booking, you can also receive exclusive discount offers from the platform.

💡 Summary: Who is ON Oen suitable for?

ON Dermatology is neither the cheapest nor the most expensive option. Its main strengths lie in its transparent pricing policy and the fact that the clinic director remains in charge throughout the entire process. If your budget ranges from NT$30,000 to NT$80,000 and you are looking for a clinic that will not engage in “upgraded sales” or have its staff changed on-site, ON Dermatology is an ideal choice.

Highly recommended for: those going to South Korea for medical aesthetics treatments for the first time (no need to worry about language barriers), those who have had negative experiences due to “doctor changes” at other clinics, and rational consumers who prefer to spend their money wisely. Although Dr. Kim Yong-hyun’s ligament reinforcement procedure costs 2.1 million South Korean won, considering the effects last for 18 to 24 months, the average monthly cost is less than NT$2,500—far more affordable than having a single Thermage treatment in Taiwan, which costs NT$60,000 and only lasts for 6 months.

❓ Frequently Asked Questions: ON Aon Q&A

Q: Does ON Dermatology accept appointments from foreigners? A: Yes, and we particularly welcome Taiwanese patients. The clinic has staff who can communicate in Chinese (translation services are arranged through s-sourire), so you can communicate in Chinese during the consultation. It is recommended to make an appointment 2 to 3 weeks in advance, as Dr. Jin’s schedule is quite busy.

Q: Can ligament reinforcement surgery be performed simultaneously with HIFU? A: Director Jin generally does not recommend undergoing two major Lifting procedures on the same day, as both treatments target the SMAS layer, and performing them together may cause excessive irritation. It is recommended to undergo ligament reinforcement surgery first and, after three months, decide whether additional HIFU treatment is needed based on the results.

Q: Is hospitalization required after the procedure? How long is the recovery period? A: Hospitalization is not necessary. Minor procedures such as linear acoustic waves and liquid lifting hardly require any recovery time; you can go shopping right after the treatment. After ligament reinforcement or HIFU treatments, there may be mild swelling for 1 to 3 days, but full recovery usually occurs around the fifth day. Director Jin will provide detailed care guidelines after the procedure, including a schedule for ice application and a list of foods to avoid.
