I. What is South Korea’s DayOne Dermatology? A local chain of dermatological clinics in South Korea
DayOne Dermatology, officially known as “DAYONE Clinic” (English: DAYONE Clinic, Korean: 데이원의원), was established in 2019 and is headquartered in Gangnam District, Seoul. It is a large-scale, mid-to-high-end chain of dermatology clinics in South Korea. Currently, the clinic operates four branches in Seoul: the main Gangnam branch, the Gangnam Station branch, the Hongdae branch, and the seasonal Myeongdong Flash Store. It is regarded by many locals in South Korea and overseas tourists as a “hidden gem of dermatology clinics”.
DayOne adheres to the core philosophy of “professional skin management and a return to the essence of medicine,” advocating for natural beauty and opposing excessive cosmetic procedures. Its medical team members are all graduates of renowned medical universities in South Korea, with an average clinical experience of over 15 years. They regularly participate in dermatological academic conferences each year, and their technical expertise has earned them a high local reputation score of 4.5 out of 5, resulting in an overall evaluation of 88 points.
II. DayOne Dermatology Gangnam Station Branch (강남역점) – Direct access via subway, located in an extremely convenient and prime location.
The Gangnam branch is the most convenient location for accessing SWOMAN. It is located on the 4th floor of Hansung Building, at 423 Gangnam-daero, Seocho-gu, Seoul (in Korean: 서울특별시 서초구 강남대로 423 한승빌딩 4층). After exiting Exit 10 of the Seoul Metro Line 2 at Gangnam Station, turn right and you will see the GS25 convenience store. Cross the road and walk straight for about 50 meters to reach the location; the entire journey takes no more than 3 minutes on foot.
The business hours of the Gangnam store are relatively long: on weekdays, it is open from 10:30 to 20:30 (with a one-hour lunch break from 13:00 to 14:00), and on Saturdays from 10:30 to 16:00. It is closed on Sundays and public holidays. It is worth noting that the store offers evening consultation services until 21:00, which is very convenient for office workers and tourists who want to receive treatment after work or while shopping.
This is the popular branch of DayOne, specializing in popular treatments such as Filler injections, Ulthrea, and Inmode. Due to its location in the heart of Gangnam’s shopping district, many tourists choose to schedule facial treatments after their shopping trips.
III. South Korea DayOne Dermatology Gangnam Main Branch – The largest institution and the top choice for anti-aging treatments
As the flagship store of DayOne, the Gangnam Headquarter covers an area of 2,000 square meters and is located on the 5th and 11th floors of the Daewon Building, at 437 Gangnam-daero, Seocho-gu, Seoul (in Korean: 서울특별시 서초구 강남대로 437 대원빌딩 5층/11층).
It is approximately 5 minutes’ walk from Exit 10 of Gangnam Station on Subway Line 2, or about 4 minutes’ walk after exiting Exit 7 of Sinnonhyeon Station on Subway Line 9. The main campus is well-equipped, featuring multiple private consultation rooms and treatment chambers, and also offers free parking services, so there is no need to worry about finding a place to park if you come by car.
As the core of DayOne’s anti-aging technologies, Gangnam General Hospital has gathered the hospital’s most experienced anti-aging specialists. It offers advanced anti-aging treatments such as Ulthera HIFU (the American version of Thread Lifting), Titanium Lifting, and cryotherapy needles. If your main goal is to achieve “tightening and lifting effects to combat the effects of gravity,” this is definitely the right place for you.
IV. Hongdae Branch of DayOne Dermatology in South Korea – The favorite choice among young people, offering great value for money
The DayOne Dermatology Hongdae branch is the youngest and most modern affiliate of the DayOne network. It is located on the 5th floor of Building 25, Hongik-ro, Mapo-gu, Seoul (in Korean: 서울 마포구 홍익로 25 5층). To get there, exit Exit 9 at the Hongdae Station on Line 2 of the subway, walk straight ahead until you reach Hongik-ro main street, then turn right. You will see Building 25 immediately – it features a gray facade, and the DayOne sign is visible on the 5th floor. Right across from the building is the entrance to the Hongdae Cultural Market, which can serve as a useful reference point. It takes approximately 5 minutes to walk from the subway exit to the clinic.
The Hongdae branch of South Korea’s DayOne Dermatology primarily targets young customers aged 20 to 30, offering high-value services such as acne treatment, Pores management, Potenza treatments, and sensitive skin relief. Compared to the two branches in Gangnam, the Hongdae branch offers more affordable prices, making it particularly suitable for young people who are new to medical aesthetics or have limited budgets.
The store also occasionally offers special discount packages designed for young skin. It is recommended to follow DayOne’s official Instagram account or WeChat public account to stay informed about the latest promotions.
V. South Korea’s DayOne Dermatology Myeongdong Pop-up Store – Seasonal offer, no reservation required
The Myeongdong Pop-up Store is a seasonal limited-time outlet of DayOne, located on the 3rd floor of Lotte Young Plaza, 11 Myeongdong 8-gil, Jung, Seoul (Korean: 서울 중구 명동8길 11 롯데영플라자 3층). Situated in the heart of Myeongdong’s shopping district, it offers the perfect convenience – you can enjoy shopping while simultaneously receiving beauty treatments.
⚠️ Important notice: The Myeongdong store is open from April to October each year and is closed during the winter season (from November to March of the following year). Please make sure to check the current month before making your trip.
Foreign tourists holding Chinese passports can enjoy the walk-in service at the Myeongdong store, allowing them to receive treatments without making an appointment in advance. This option is particularly suitable for independent travelers with limited time and flexible itineraries. However, due to the fast-service format of this store, the range of services offered may not be as comprehensive as those at the Gangnam and Hongdae stores. For more complex procedures, it is recommended to visit other branches.
