Before going to Cheongtan for Thermage treatment, I compared three different options and chose this one: KSY Dermatology – A Real Experience缩略图

To be honest, when I was looking for anti-aging treatments in Cheongtan, Seoul, I visited many clinics, and most of them just asked me whether I wanted Thermage or ultrasound treatments, without asking about the specific issues with my skin or what was bothering me the most. Later, a friend recommended KSY Dermatology (Kim Song-ee’s Clinic), saying that the doctors there would actually take the time to analyze my skin instead of just following a standard procedure. I decided to give it a try, and I found that this clinic was indeed different. In this article, I will share my entire experience during the consultation and treatment at KSY in Cheongtan.

What kind of clinic is KSY Dermatology in Cheongtan? They offer both Thermage FLX and Sofwave treatments.

KSY Dermatology (Kim Song-ee’s Clinic) is located in Cheongtan-dong, Seoul, just a three-minute walk from Deo Station on the Suin-Pyeongtaek Line. The clinic is operated by three dermatologists: Kim Song-ee, Park Ji-yoon, and Jin Gang-ee. All three are specialists in dermatology, and each has their own area of expertise.

The clinic’s main selling point is that they do not follow a standard procedure; each patient receives a personal consultation and a customized treatment plan designed by the doctor themselves. Their official term for this approach is “Signature Tailored Treatment,” which means personalized care. For someone like me with an asymmetrical face and various minor skin issues, this concept really appeals to me.

In terms of equipment, KSY is equipped with two popular anti-aging devices: Thermage FLX and Sofwave. These can be combined with other treatments such as Go-Back injections and fillers, depending on the patient’s needs.

II. Latest reference prices for Thermage FLX & Sofwave at KSY Dermatology in Cheongtan for 2026

Here are the prices I received regarding KSY’s services (these are 2026 reference prices; actual fees may vary according to the clinic’s pricing):

  • Thermage FLX: Starting from ⩡2,500,000 won (depending on the number of sessions and treatment areas)
  • Sofwave: Starting from ⩡1,200,000 won (full-face treatment, excluding the neck)
  • Filler/injection treatments: Prices are determined after a personal consultation based on the individual treatment plan.

Compared to the expensive clinics in Cheongtan-gu, which often charge over ₩3,000,000 for treatments, KSY’s prices are considered reasonably moderate in the area. More importantly, they won’t recommend unnecessary procedures—they will tell you what is most effective for your current needs. During my first consultation, the director clearly stated, “What you need now is not Thermage; a single Sofwave treatment is enough.” Such honesty really impressed me.

III. What are the differences between Sofwave at KSY Dermatology in Cheongtan? How to choose between it and Thermage FLX?

Many people come to KSY with the intention of getting Thermage, but the director will explain in detail the differences between the two devices during the consultation. Simply put:

  • Thermage FLX: Uses high-frequency radio waves to heat the dermis and subcutaneous fat, focusing on tightening and lifting. It is suitable for those with noticeable skin laxity. Results are immediate, and the effects last for a relatively long time.
  • Sofwave: Combines ultrasonic and RF energy to target the fascia layer. It causes less discomfort and is ideal for preventive maintenance or mild skin laxity. The price is also more affordable.

KSY’s approach is to understand that not everyone needs the most expensive option. The director will recommend the most suitable treatment based on your facial condition, budget, and recovery requirements. I think this approach is very responsible, because some people really only need Sofwave and don’t need to spend extra money.

If you are trying a tightening treatment for the first time, or if your skin condition is good but you just want to maintain it, Dr. KSY usually recommends Sofwave first. If you already have noticeable wrinkles or drooping cheeks, Thermage FLX will be more effective.

IV. How does Dr. Kim Song-ee conduct her consultations? Why do clients have such a high return rate?

KSY has a rating of 4.6 and 35 genuine reviews, which is quite impressive in the competitive Cheongtan area. I think the reason lies not in the advanced equipment, but in the thoroughness of her consultations.

Dr. Kim Song-ee is the founder of the clinic. Her consultation process goes like this: First, she asks you about the areas that bother you the most. Then, she uses a flashlight to carefully examine your face—checking your eyes, wrinkles, drooping cheeks, and skin texture. Only after that does she share her recommendations and explain why certain treatments are suggested, what the results will be, and how long they will last.

The entire consultation took me about 20 minutes, and I didn’t feel rushed at all. A friend who went with me said that at other clinics, the consultation lasted only five minutes before they started quoting prices, without any real attention to the client’s needs. Many of KSY’s clients are regulars from Cheongtan precisely because they trust this approach.

V. What is the environment like at KSY Dermatology in Cheongtan? The first floor is very modern.

KSY’s clinic is located at 15, 158 Seollin-ro, Cheongtan-dong. The space is small but stylishly designed, with a clean and modern vibe that doesn’t resemble traditional clinics. The waiting area features chairs with a distinctive design, and the overall atmosphere is quiet, unlike some larger clinics that can be crowded and noisy.

When I visited, there were two treatment rooms, and the equipment seemed well-maintained. The nurses and assistants were very friendly, and you could express any discomfort at any time. The whole experience felt more like receiving VIP care rather than being treated in a fast-paced, impersonal manner.

Geographically, it’s only about a three-minute walk from the Deo Station exit on Yapgyo-tong Road. Parking in the Cheongtan-dong area is also convenient, with both roadside parking spaces and garages available nearby.
