I. Who is Sirait Secret Dermatology? Get to know its philosophy in one go.
Sirait Secret Dermatology (시크릿의원) is located just a short walk away from Exit 6 of Sinnohnhyun Station in the Gangnam district of Seoul. It is a dermatology clinic that focuses on “one-on-one personalized treatment by female doctors” as its core concept.
Unlike many chain dermatology clinics where patients are treated by staff members who rotate frequently, Secret Dermatology believes that every patient’s skin condition is unique. Therefore, from the initial consultation and treatment planning to the actual procedure, everything is handled personally by the director to ensure that each step meets the individual patient’s needs.
This “high-quality” service model has earned Secret Dermatology numerous positive reviews on review platforms such as Naver and Gangnam언니, attracting many medical beauty tourists from Taiwan, Hong Kong, and Japan who specifically visit the clinic.
II. Introduction to the directors: A professional team of two experienced female doctors
Currently, Secret Dermatology is led by two directors who have clear roles and specialized areas of expertise.
(I) Director Jo Yoo-sang
As the representative director, Jo Yoo-sang possesses extensive clinical experience in skin beauty treatments. She has worked at several well-known medical beauty clinics in Seoul, including 예쁨주의 쁨의원, 톡스앤필의원, 오빗의원, and others. Her expertise covers a range of areas including injectable procedures, laser treatments, and skin management.
Her style is known for being “delicate and precise.” She specializes in creating customized treatment plans for each patient based on their skin type and facial structure, avoiding one-size-fits-all approaches and maximizing the effectiveness of each treatment.
(II) Director Kwon Dam-woo
Director Kwon Dam-woo graduated from Seoul National University Hospital and has a solid academic background. She is also a member of several Korean dermatological and cosmetic associations:
- Official member of the Korean Association of Aesthetic Plastic and Laser Medicine
- Official member of the Korean Society of Dermatological Obesity Plastic Surgery
- Official member of the Korean Society of Aesthetic Obesity Medicine
- Official member of the Korean Filers Association
She has extensive clinical experience in injectable aesthetics (hyaluronic acid, botulinum toxin), contour management, and skin quality improvement, which has earned her the trust of repeat customers.

III. Overview of Main Treatments: From Lifting and Tightening to Skin Quality Management
Secret’s dermatological treatments are centered around “personalized customization.” Below are some of the most popular treatments to help you prepare before your visit.
(I) Lifting Treatments
This is Secret’s flagship treatment. The clinic uses a variety of top-tier devices to customize the energy delivered based on each person’s facial structure, fat distribution, and muscle tension, ensuring more lasting and natural results.
- Ulthera: Deep SMAS facelifting with results lasting 1 to 1.5 years

- Secret Skin Care Program: Designed for multiple sessions to address various issues such as redness, pigmentation, and enlarged pores.
(III) Micro-injection Treatments (Fillers & Botox)
Secret Dermatology only uses genuine hyaluronic acid products that are 100% transparent. The appropriate brand and concentration of fillers are selected based on each patient’s skin type, target areas, and facial structure, to avoid the “internet-famous face” look and achieve a natural-looking result.
- Hyaluronic Acid Filling (for areas such as under the eyes, nasolabial folds, and temples)
- Botulinum Toxin Injections (for the forehead, corners of the eyes, and jaw muscles)
- Contour Injection Treatments: For a smaller face and reducing jowls
(IV) Pigmentation Removal and Whitening Laser Treatments
