I had two treatments with the ultrasound knife, but both times my skin became red and swollen. It wasn’t until I went for a in-person consultation at Lin Ershi’s Dermatology Clinic that I found out what the problem was.

I have very sensitive skin and am quite particular when it comes to treatments.

After undergoing several cosmetic procedures in Seoul, I must admit I got ripped off twice—once at a clinic in Gangnam where the ultrasound treatment left my skin red for almost three weeks. The nurse said it was normal, but I suspected the intensity was too high; however, I had no way to verify it, so I just let it go.

Later, a friend recommended that I try Im Lee-seok’s Theme Dermatology near Sinsa Station. She said, “This clinic has been open since 1995. The owner himself is a dermatology doctor, and they never overprescribe treatments.” After thinking about it, I decided to go for a consultation.

First question: Why does Im Lee-seok’s Theme Dermatology still have so many returning customers after all these years?

Im Lee-seok’s Theme Dermatology opened in Sinsa-dong in 1995, and nearly 30 years have passed since then. This alone makes it quite rare among dermatology clinics in Gangnam District—after all, new clinics open and close quickly in this area.

Dr. Im Lee-seok himself graduated from the School of Medicine at Chung-Ang University. He obtained his specialist certification in dermatology in 1989 and later continued his studies at Shuntdo University in Japan, where he earned a Ph.D. in dermatology. He has also appeared frequently on TV shows such as SBS, KBS, MBC, JTBC, and YTN to discuss skin-related issues. Today, the clinic employs seven dermatology specialists and continues to maintain the practice format established by the founder, avoiding outsourcing services.

Such a background gave me some peace of mind—it wasn’t just another marketing-driven online-famous clinic, but a place that truly relies on its technical expertise to operate for nearly thirty years.

Second question: How do I get to Im Lee-seok’s Dermatology from Exit 4 of Sinsa Station? It’s only a 5-minute walk, right?

The clinic is located at: 78 Narute-ro, Sujeong-gu, Seoul (19-9 Canwon-dong), Floors 1–5 of Im Lee-seok’s Theme Dermatology Building. The entire building belongs to them, including the two underground floors—no wonder they can accommodate over 70 devices there.

Transportation: Exit 4 of Subway Line 3, Sinsa Station. It’s about a 5-minute walk. Just follow the direction of Garosugil (Shaded Road); the intersection is easily recognizable. There are also bus and taxi stops nearby. Since it gets crowded in the afternoon and on weekends, it’s advisable to arrive a bit earlier.

I went there on a Wednesday afternoon. As soon as I entered, I saw the signboards on the first floor that clearly indicated the functions of each floor: 1F was the hair loss treatment center and hair transplantation center, 2F was the dermatology and laser clinic, 3F was the Aesthetic beauty space, and 5F was the skin research institute. Just the fact that it was divided into so many floors made it feel different from many small clinics.

Thirdly, those 70 devices are not just empty promises—what exactly are the advanced treatments offered by Lin Ershi Dermatology?

My main concern was improving my skin’s firmness, so I specifically asked the consultant about the equipment available on the 2nd floor. She told me that the main machines used for anti-aging treatments at the clinic included:

• Ulthera P Prime ultrasound device (US version) — she said Dr. Lin used a more conservative approach and did not increase the intensity to achieve immediate results, which reassured me.
• Thermage FLX — suitable for improving facial elasticity, reducing fine lines, and defining contours.
• Shurink ultrasound lifting — can be used for the eye area, nasolabial folds, and jawline.
• Titanium Lifting — a new concept treatment using three wavelengths simultaneously.
• Doublo — a high-intensity ultrasound lifting therapy certified by the Korean Food and Drug Safety Agency.
• Emface — stimulates muscles to reduce wrinkles and promotes collagen production.

By the way, in addition to anti-aging treatments, they also offer a wide range of pigmentation and laser services, such as Lumenis Pico4, Fotona QX Max, V-Beam Perfecta (for facial redness), and Scarlet (for pores and scars). If you have persistent pigmentation or inflammation issues, they have plenty of effective treatments available.

IV. On the day of the consultation, Director Lin Ershi of the Dermatology Department personally came in—different from what I had imagined.

I had expected that an assistant might handle my consultation, but when I entered the room, it was Director Lin Ershi himself who sat down with me. He was very direct; he didn’t try to sell me anything right away but asked about the issues that concerned me the most.

I told him about the redness that occurred after the ultrasound treatment, and he explained that the reaction to ultrasound varies from person to person. However, if it lasted for more than a week, it usually meant that the energy setting needed to be adjusted. He said that when he performed ultrasound treatments himself, he would first test a small area to observe the patient’s reaction instead of starting with full-face treatment at high energy levels.

He evaluated my skin condition and suggested that I would be better off starting with Thermage FLX combined with Titanium Lifting rather than undergoing ultrasound treatment right away, because my skin needed to improve its elasticity before considering deeper lifting procedures. This approach made me feel that he was truly assessing my skin needs rather than just trying to sell me a service.

The entire consultation took about 20 minutes, which was longer than I expected. No staff members rushed me, and no one presented me with a quote for immediate decision-making. I said I needed some time to think it over, and he agreed, offering me a consultation form to take home and consider.

V. The environment at Lin Ershi Dermatology Center—what does a 5-story dermatology clinic look like?

The clinic’s environment was even better than I had imagined. The entrance on the first floor featured a marble background wall with the clinic’s golden logo, and the reception area was designed with a modern touch. The orange leather waiting chairs added a warm feel to the space.

The corridors were wide, and the lighting was soft and bright enough without being harsh. The entrance to the laser center on the second floor had a glowing sign that read “LASER CENTER.” The treatment rooms were equipped with more than ten devices, and the space was well-organized, with no cluttered equipment in corners. The aesthetic care area on the third floor was even quieter, with curtains separating the two treatment beds, locked storage cabinets, and soft lighting.

Overall, the clinic gave me the impression of being “ understated, clean, and professional”—there were no excessive advertising posters or screens playing promotional videos; it was simply a reliable medical space.
