There are simply too many Dermatology clinics in Gangnam, Seoul – every time I see various recommendation posts, I get a bit overwhelmed: which brand of Thermage is genuine, and which company offers really good hyaluronic acid treatments? Last year, while doing some research, I kept coming across one name: DAYONE Dermatology General Hospital. After reading numerous reviews, I found that it had a very good reputation among locals, and it had been in operation for many years without any negative reports. Finally, I decided to make an appointment for a consultation. Today, I am sharing my complete experience and research findings with you, in case you are also struggling with this decision.
I. What is DAYONE Dermatology General Hospital? | Background and Reviews of This Established Dermatology Institution Located on Gangnam-daero, Seocho District, Seoul
DAYONE CLINIC, the flagship institution of the Dermatology department, is located on the 5th floor of the Dayuan Building at 437 Gangnam-daero, Seocho-gu, Seoul, in the heart of Gangnam’s commercial district. Since its establishment, the clinic has specialized in the field of skin care, adhering to the philosophy of “getting a little better every day than the previous day” and renowned for its accurate diagnoses and transparent pricing.
According to data from the BeautsGO platform, the DAYONE main clinic is equipped with 1 chief physician, 7 junior doctors, and 6 nurses. It provides Chinese translation services (both for clinical consultations and documentation), making it one of the few Gangnam Dermatology clinics that explicitly offer language support. The clinic has consistently appeared on South Korea’s local Naver Dermatology recommendation lists, promising “rigorous selection of medical professionals, verifiable medical qualifications, and transparent service practices” as its core commitments.
Compared with other local clinics, DAYONE has several notable features: it does not offer standardized treatment plans – each customer must undergo a skin CT examination before the consultation, and personalized treatment parameters are determined based on data such as skin thickness, moisture content, and melanin distribution; the prices are clear and transparent, with Chinese price lists available in the consultation rooms, and hidden fees are strictly prohibited; in addition, on-site tax refunds are supported, making DAYONE particularly user-friendly for visitors from Taiwan, Hong Kong, and Southeast Asia.
II. Address, Transportation, and Opening Hours of DAYONE Dermatology General Hospital | Easy access from Seoul Gangnam Station – Detailed directions to the hospital
Whether it is your first time in South Korea or you have visited many times before, understanding the details of transportation is crucial to avoiding unnecessary trips. Below is a guide to getting around that I have personally compiled:

💡 Tip: After exiting Gangnam Station, walk in the direction of Gangnam-daero. Your destination is the Daewon Building; take the elevator to the 5th floor to reach the reception area of the clinic. If you are coming from Myeongdong or Hongdae in Seoul, it is most convenient to take Line 2 and make the transfer – the entire journey takes no more than 30 minutes.
III. Analysis of Key Services at DAYONE Dermatology General Hospital | Features of Thermage FLX, Inmode Inmode, and Rejuran Hydrating Technologies
The product range of DAYONE General Hospital covers everything from basic skin care to advanced anti-aging treatments. Below, we will focus on introducing several of the most popular and highly recommended treatments:
- Genuine Thermage FLX: DAYONE emphasizes “strict selection across Korea, verifiable medical qualifications, and transparent consumption practices.” It uses globally certified genuine Thermage equipment, and the medical professionals’ qualification records are available for inspection. Thermage utilizes radiofrequency energy to heat the dermal collagen layer, achieving non-surgical lifting and tightening effects – making it ideal for people in their early to middle ages who wish to combat aging.
- INMODE Inmode: It also introduces genuine equipment in accordance with the “strictly selected from across Korea” standard. INMODE possesses both lipolysis and skin-tightening effects, enabling precise shaping of the face and specific areas of the body (such as the jawline and abdomen). It has become an increasingly popular premium option among those who pursue beauty in recent years.
- Ultherapy Prime (US version): The hospital has independently developed the “Multi-Dimensional Vector Lifting Technique” to precisely target the SMAS layer, enabling non-invasive contour tightening and reshaping. The results of this treatment last for 1 to 2 years, making it the most natural alternative to surgical Lifting procedures.
- Rejuran Healer Black Box: This product contains a high concentration of PN polynucleotides, which help repair the skin’s barrier from within, reduce inflammation, and slow down the aging process. It is suitable for people with sensitive skin or those who are allergic to Filler. Dr. Zhao Wenjing is renowned for her delicate, layered injection techniques, which focus on achieving natural results and long-term durability.
- Juvelook Collagen Filler (Blue Bottle): Specifically designed for Tear trough correction, Nasolabial Fold Correction, and Buccal Fat augmentation. Combined with a collagen-stimulating factor, its effects are more lasting than those of traditional Filler, and the skin quality also improves simultaneously.
In addition, the hospital also offers services such as German Cela (for even skin tone improvement), Pico laser treatment (Pico Toning), and chin line Jogak packages (a combination of fat-reducing injections and Lifting laser treatments), providing one-stop solutions to meet various skin care needs.

VI. The complete process of making an appointment at DAYONE Dermatology General Hospital | A personal experience sharing of the entire process from visiting a clinic in South Korea to finalizing the payment
I made my appointment at the DAYONE General Hospital through the BeautsGO platform, and the entire process went much more smoothly than I had imagined. Here are the steps I followed:
- Search for “DAYONE Dermatology General Hospital” on BeautsGO, click “Book a Consultation”, and fill in the desired appointment date and the treatment you would like to receive (I chose Thermage + Rejuran hyaluronic acid injection).
- I received a confirmation message from the Chinese customer service, which informed me of the scheduled appointment time and the necessary precautions (avoid sun exposure before the procedure and come to the clinic without makeup).
- On the day of arrival at the clinic: There is Chinese-speaking staff at the reception. First, you need to fill out a skin questionnaire, and then undergo a skin CT scan. Please wait for approximately 10 minutes.
- During the in-person consultation, the doctor analyzed my skin condition item by item based on the CT report and clearly explained the reasons for the recommended treatments, without any sense of forcing me to choose anything. I decided to opt for the Rejuran + Pico laser treatment combination.
- Treatment duration: Approximately 1.5 hours. Throughout the process, a nurse will accompany the patient in Chinese, ensuring that any discomfort experienced remains within an acceptable range.
- Settlement and tax refund: The price shall be in accordance with what was stated during the reservation process. Tax refunds can be processed on-site, and the entire process is clear and straightforward.
On the third day after the procedure, the mild redness had basically subsided, and one week later, the quality of my skin had significantly improved, with increased moisture levels. The overall experience exceeded my expectations – especially the pre-procedure CT scan, which made me feel that “this wasn’t just a formality”.
VII. Real User Reviews from DAYONE Dermatology General Hospital | Experiences of Beauty Seekers from Taiwan, Hong Kong, and Singapore
“I searched for a long time in Taiwan and finally booked the Thermage treatment at the DAYONE headquarters through BeautsGO. Before starting the procedure, the doctor explained each step in detail, and a Chinese translator was present throughout the whole process, so I didn’t feel nervous at all. When it came to paying, the price was exactly the same as what was mentioned during the booking process; ther
e were no additional charges at all. Highly recommended!”
— Amanda, a beauty seeker from Taipei, Taiwan
“What I had was the Rejuran glow injection treatment. Dr. Zhao Wenjing is extremely meticulous in her technique; the injections are applied in precise layers, so there is no swelling at all after the procedure. I was able to see my clients normally just the next day after returning to Hong Kong. What I really appreciate about her is that she doesn’t keep pushing me to add more tre
atments or do things that I don’t need. She just does what is best for me.”
— Christine, a beauty seeker from Hong Kong
“I was referred by a friend. I originally only planned to undergo basic skin care treatments, but after the consultation, the doctor recommended adding the Juvelook procedure, and my Tear trough correction was immediately effective! The prices are transparent, and the tax refund process is also very convenient. Even after returning to Singapore
, I’m still thinking about getting the INMODE treatment next time.”
— Michelle, a beauty seeker from Singapore

X. FAQ: Common Questions Answered by DAYONE Dermatology General Hospital
Q1: Is DAYONE Dermatology General Hospital suitable for beginners who are going to South Korea for medical beauty treatments for the first tim
e?
A: It is very suitable. The hospital provides Chinese translation services, and a skin CT examination will be conducted before the consultation. Doctors will explain the necessity and expected results of each treatment in a way that you can understand, so there is no pressure from sales attempts throughout the process. By making an appointment through BeautsGO, you can also confirm the details of the treatments and prices in Chinese in advance, so you won’t encounter any surprises when you arrive at the hospital.
Q2: Is there a recovery period after undergoing Thermage treatment? How many days in advance is it appropriate to schedule t
he procedure?
A: Thermage is a non-invasive treatment. After the procedure, there may be mild redness or a feeling of heat on the same day, but these symptoms usually subside within 24 to 48 hours and do not affect daily activities. If your schedule is tight, you can consider having the treatment done on the evening before returning to Taiwan/Hong Kong.
Q3: What is the difference between Rejuran Healer and regular hyaluronic acid fillers?
A: The main component of Rejuran Healer is PN polynucleotides (derived from salmon DNA), which is different from regular hyaluronic acid fillers, whose primary ingredient is hyaluronic acid itself. Rejuran focuses on repairing the skin barrier, reducing inflammation, and anti-aging effects; it is suitable for sensitive skin, improving acne scars, and enhancing the health of the lower layers of the skin. Regular hyaluronic acid fillers, on the other hand, mainly serve to instantly hydrate and brighten the skin. The DAYONE Black Box version contains a higher concentration of PN, resulting in more lasting effects.
Q4: Is it possible to change the service or date temporarily after making a rese
rvation?
A: Users who have reserved through BeautsGO can directly contact the Chinese customer service of BeautsGO if they need to change the appointment time or service. Generally, providing 48 hours’ notice in advance allows for proper coordination. It is also recommended to inform us as early as possible if you decide to cancel your appointment, so as not to occupy someone else’s schedule.
Q5: After undergoing a treatment at DAYONE, is it possible to get a tax refund in South Korea?
A: Yes. The DAYONE Dermatology headquarters provides on-site tax refund services for visitors holding foreign passports. Whether a medical treatment qualifies for a tax refund depends on the policies in effect on the day of service; it is recommended to inquire with the front desk upon arrival.
