[South Korea’s 2% of Specialist Doctors] Director Choi Jae-won | Seoul Lumiin Dermatology: One-on-one appointments with specialist doctors

True dermatological treatment relies on a doctor’s extensive experience and solid diagnostic skills. Today, we will delve into the secrets of “Seoul lumiin Dermatology (lumiin Skin Clinic / 루미인피부과)”, which has topped the list of most popular clinics in Seoul for five consecutive years, as well as its key figure: Director Choi Jae-won, who holds the highly coveted title of “Dermatology Specialist” in South Korea.

崔在元醫師（Dr. Jaewon Choi） 為韓國皮膚科專科認證醫師，現於韓國首爾江南區執業，專精於以皮膚科醫學為基礎的醫學美容與皮膚健康管理。其臨床重點著重於皮膚結構、皮膚再生機制，以及長期皮膚健康狀態的穩定與維持。

崔在元醫師認為，真正有效的皮膚治療應建立在皮膚科醫學原則之上，而非僅追求短期的外觀改善或暫時性的美容效果。

👨‍⚕️ I. Getting to know Representative Choi Jae-won, the Dean of the Department: Only 2% of dermatology specialists in Korea are truly qualified professionals.

In South Korea, there is a significant gap between “Dermatology doctors” and “doctors who perform cosmetic medical procedures.” After graduating from medical school, one must undergo several years of specialized clinical training and pass rigorous assessments at university hospitals. The elimination rate is extremely high, and ultimately, only about 2% of doctors in South Korea obtain the “Dermatology Specialist” license issued by the Ministry of Health and Welfare. Director Choi Jae-won is one of those who have succeeded in this process.

🎓 Dean Cui Zaiyuan’s educational background and work experience

• Graduated from the Department of Medicine at Hanyang University

• Completion of residency training in Dermatology at Asan Hospital in Seoul

• Master’s degree from the School of Medicine, Ulsan National University (specializing in Dermatology)

• Former presidents of Doctors Dermatology and Meijia Ge Ren Dermatology

• Consultation with a doctor provided by the South Korea International Cooperation Agency (KOICA)

• In 2018, the Korean Society of Dermatopathology won the “Best Presentation Award”.

• Official member of the Korean Dermatology Society, Korean Anti-Aging Research Society, and Korean Dermatologists Association

Director Choi comes from a three-generation medical family specializing in Dermatology. His father is also a seasoned veteran with over 20 years of experience in the field of dermatology. Thanks to the family’s medical heritage and the rigorous training at a top-tier hospital like Asan Hospital in Seoul, Director Choi has achieved an exceptional level of expertise in understanding the structure of skin cells, pigment metabolism, and the immune system.

💡 II. Dean Cui Zaiyuan’s Medical Beliefs: The “Underlying Logic” Behind Anti-aging and Freckle Removal Treatments

During the one-on-one consultations, what Dean Cui always mentions is: “The purpose of medicine is not to make people look different from who they really are, but rather to restore the vitality of the skin system and bring it back to its healthy state.”

1. Therapeutic anti-aging: Say no to blindly “just going through the motions”

Director Cui is not particularly fond of the purely commercial term “anti-aging.” In his view, skin aging is a chain reaction involving the collapse of the dermis, the decline in cellular function, and the damage to the skin’s barrier. When performing treatments such as the American version of Thermage FLX or ultrasonic lifting, he refuses to use any type of mass-produced, assembly-line approach. Instead, he personally assesses your daily routine, muscle patterns, and fat distribution, precisely determining the treatment vectors to deliver the exact amount of energy directly to the fascia layer, thereby creating a natural, supple, and sophisticated contour.

2. Precise Pigment Management: The Ultimate Reepot Laser

Skin pigmentation disorders such as chloasma, brownish patches on the cheeks, freckles, and age spots are among those that are most prone to experiencing recurrence or darkening due to misdiagnosis. Director Cui specializes in laser treatment for these conditions, and his clinic was among the first in China to introduce the revolutionary Reepot laser equipment. During consultations, Director Cui uses specialized diagnostic instruments to conduct a 15-minute in-depth analysis of the skin’s pigmentation layers. By leveraging Reepot’s technology for automatic detection of pigment depth, he can precisely target melanin deposits, thereby minimizing the risk of post-treatment redness or darkening.

3. Multidimensional and layered interventions for acne and acne scars

For sunken acne scars and stubborn marks left by acne, Director Cui refuses to rely on ineffective single-laser treatments. Instead, he advocates for a comprehensive approach:

This multi-dimensional medical approach can effectively fill in the depressions at their source and restore the skin to its delicate texture.

💰 III. In 2026, Director Cui Zaiyuan will personally conduct consultations: Reference prices for popular treatments (including taxes; same prices in China and Korea)

Seoul’s Lumiin Dermatology is renowned in the Gangnam area for its high ethical standards and refusal to engage in aggressive sales practices. The director personally advises patients against undergoing treatments that may not be suitable for them, and the clinic strictly adheres to the same prices in both China and Korea, with all fees clearly listed (including the latest VAT rates for medical aesthetics in 2026).
