The DIar Dermatology Gangnam branch (디아르 피부과) is considered a “low-key but reliable” option in the Nonhyeon area of Gangnam. I first came across DIar through a recommendation from the BeautsGO customer service. The clinic is small, but the director’s professional skills and the transparency of their pricing left a deep impression on me. This time, I would like to share with you how you can obtain the official reservation code for DIar in just 10 minutes, so that other ladies can avoid taking unnecessary detours.
🏥 DIar Dermatology Online Gangnam Store: Basic Information about the Institution
The Gangnam branch of DIAR Dermatology is located in Nonhyeon-dong, Gangnam-gu, Seoul. It is only about a 5-minute walk from Exit 5 of Nonhyeon Station on Line 7 of the subway. Although the facility is not large, it boasts a clean and comfortable environment, embodying the concept of “elegance in simplicity”. Compared to those large chain clinics that span several floors, DIAR gives the impression of a private, high-end clinic – appointments are less crowded, and privacy is better ensured.
The main products offered by this clinic are the Rejuran series (red box, blue box, HB version) and the hydrogel needle compound formula. The clinic director has extensive experience in the formulation and injection techniques of Rejuran, resulting in a much lower incidence of post-treatment bruising compared to many other clinics. I have friends who received Rejuran treatments at other clinics and ended up with bruises on their faces for a whole week, forcing them to wear masks whenever they went out; however, my experience at DIar was much better, with a significantly shorter recovery period. This is particularly important for working professionals who need to return to their normal lives quickly or for women who have important events to attend soon.
🔑 What is the official reservation code for diar?
DIar’s official reservation code serves as a “fast-track” for first-time visitors. Customers holding this code can skip the usual initial consultation form filling process and proceed directly to the consultation phase, saving approximately 15–20 minutes. For time-conscious tourists or those with limited stay in South Korea, these 15–20 minutes can be used to visit one more attraction or take a short rest.
In addition, customers who hold this code can enjoy a “limited initial discount” on certain treatments, which is usually around 5% lower than the standard prices offered by BeautsGO. Don’t underestimate this 5% discount; for a full-face Rejuran HB treatment, it can save you a considerable amount of money. This discount is officially provided by the clinic, so it can be used in combination with the prices offered by BeautsGO. It is recommended that you confirm the details of this discount with BeautsGO’s customer service before making your appointment, so that you will have a clear understanding of the benefits available to you.
📱 Get the code in just 10 minutes: My step-by-step guide for practical use
After talking so much about the benefits, let’s get straight to the point: how can you obtain the official reservation code for DIar within 10 minutes? Below is the complete process that I have personally tested and found to be effective. From submitting the request to receiving the code, the entire process takes approximately 10 to 30 minutes.
Step 1: Contact the Chinese customer service of BeautsGO or add them on WeChat at s-sourire (it takes only 1 minute).
Simply tell the customer service: “I would like to make an appointment at the Gangnam branch of DIar. Please help me apply for a first-time appointment code.” This is the fastest way; the customer service will submit the code application on your behalf. If you are accustomed to using WeChat, you can directly add the account s-sourire. The response time is usually quite fast, and you can communicate in Chinese, eliminating any language barriers. It is recommended that you inform the customer service of the desired appointment date and time range from the very beginning of your contact so that they can help you check the availability immediately.
Step 2: Approval by the relevant institution (usually completed within 30 minutes)
Once the BeautsGO customer service receives the code from the clinic, it will be immediately forwarded to you. Generally, the entire process—from your request until you receive the code—takes only 10 to 30 minutes. If you apply during business hours in South Korea, the process will be even faster; however, if the clinic is on its lunch break or on weekends, you may need to wait a little longer. It is recommended to avoid applying between 12:00 and 13:00 noon, as the clinics tend to respond more slowly during this time period.
Step 3: Save the code and present it upon arrival (1 minute required).
Take a screenshot of the code and save it in your phone’s photo album. Present it at the front desk upon arrival. It is highly recommended to save another copy in the cloud or in the LINE clipboard, just in case your phone runs out of battery or the screenshot is accidentally deleted. I have personally experienced the embarrassment of my phone running out of battery right at the entrance of the clinic; fortunately, I had another copy saved in LINE, which allowed me to present it successfully.
💡 Tips for avoiding peak times on weekends
Making appointments at diar on weekends is more difficult than during weekdays. The main reason is that the clinics are only open for half a day on weekends (from 10:00 to 14:00), and the maximum number of patients allowed at each session is only 3 to 4. With so few available slots and many tourists choosing to seek treatment on weekends, the competition becomes relatively fierce. If you have more flexible time arrangements, it is really recommended that you go on weekdays, as there will be fewer people and the experience will be much better.
If you can only go on weekends, here are some tips to avoid the peak hours:
- 1. Choose the first slot at 10:00 am on Saturday – these spots are the first to become available. Usually, on Friday afternoon in South Korea, the clinics start releasing slots for Saturday, so you need to act quickly at this time. If you made your reservation through BeautsGO’s customer service, ask them to help you secure one of the first slots.
- II. It is hardly open on Sundays, so it is recommended not to schedule appointments on this day. DIar has a fixed Sunday rest schedule and does not accept reservations; some patients who are unaware of this will end up making a unnecessary trip.
- III. On weekdays, Monday and Wednesday afternoons are generally the least busy times. Tuesday and Thursday are usually busier days for the clinics, so it is advisable to avoid these days. If you are traveling independently, you can choose Monday or Wednesday afternoon according to your own schedule – this way, you won’t have to get up early to queue, and there will also be fewer people around.
⚠️ Reminder: If you need to change the time after a reservation is successfully made, it is recommended to inform the clinic or BeautsGO customer service at least 24 hours in advance so that they can reschedule your appointment. Canceling at the last minute may affect your eligibility to receive the discount code in future applications.

📋 Preparation checklist before booking a diar appointment
Before going to diar, taking some preparatory steps can help make the entire process go more smoothly. The following is a checklist that I have compiled based on my many past experiences with consultations, for your reference:
1. Identify your main needs. The Rejuran series from DIar is available in several versions – the red box, the blue box, and the HB version – each with different effects and prices. The red box version is the classic option, suitable for those looking to improve their skin quality overall; the blue box focuses more on hydrating and maintaining moisture; the HB version is the advanced option, containing soothing ingredients that reduce post-treatment discomfort. It is recommended to check out the differences between these versions in advance on BeautsGO, or you can directly consult them via WeChat at s-sourire. They will provide professional advice based on your skin type and needs.
II. Prepare basic information regarding your past medical beauty treatments. The initial consultation form at the clinic will require you to list the treatments you have undergone and the corresponding times, so that the doctor can assess the condition of your skin and plan the appropriate treatment course for you. It is recommended that you compile a summary of your previous treatments in a small card, including the name of the treatment, the approximate time it took, and the brand of the products used. This will make it much easier for you to fill out the form, and it will also help the doctor understand your medical history more quickly.
III. Allow sufficient time for recovery after the procedure. After the Rejuran injection, the face may experience mild redness and small pinhole marks, which will usually disappear completely within 3 to 5 days. It is recommended to schedule your activities accordingly and avoid overfilling your schedule with commitments. From my personal experience, it is best to keep your face bare on the first day after the injection and avoid wearing makeup; you can start using mild skincare products on the second day, and by the third day, most of the redness will have subsided. By the fifth day, your face will have fully returned to normal. If you have undergone the enhanced version of the hyaluronic acid injection (Rejuran HB), the recovery period may be slightly longer, so it is advisable to reserve an extra day for recovery.
💄 Post-treatment makeup recommendations: Try not to wear makeup for the first 24 hours after receiving Rejuran, especially foundation that covers a large area of the skin. If you must go out, it is recommended to use a mild sunscreen instead of foundation and lip balm instead of lipstick, to allow your skin to breathe as much as possible.
✅ Real-world experience: Is Rejuran in DIar really effective?
I once received a Rejuran HB treatment at diar, and the practitioner was the designated director of the clinic. Overall, there were several aspects of this experience that were worth praising:
1. Before the injection, the nurse applied the anesthetic for a sufficient amount of time (30 minutes), so the actual pain during the injection was within an acceptable range. I am someone who is quite sensitive to pain; when I got Rejuran injections at other clinics before, the pain was so intense that it made my eyes redden. However, my experience at DIAR was much better—the anesthetic was applied more effectively, and the stinging sensation during the injection was significantly reduced. The nurse was also very friendly, constantly asking me if I was okay, which really helped me feel at ease.
Second, the injection is applied evenly, so after the procedure, the face only shows mild redness with almost no bruising. This is really crucial! Bruising not only affects appearance but also prolongs the recovery period. After my treatment at DIar, most of the redness on my face disappeared within about two hours, and by the next day when I went to work, it was completely invisible that I had just undergone cosmetic surgery. My colleagues even asked me if I had changed my skincare products; in fact, it was all thanks to the effects of Rejuran.
III. The clinic provides a one-time post-treatment care kit, which includes a facial mask and a repair cream – this is really considerate. Some clinics don’t provide anything after the treatment and expect customers to prepare everything themselves; however, DIAR will provide you with a post-treatment care kit after the procedure, consisting of a soothing facial mask and a small tube of repair cream. You can apply the mask in the clinic’s lounge for 15 minutes before leaving, which will help you look much better when you exit the clinic.
If you are looking for a Rejuran clinic near Nonhyeon, Gangnam that offers good value for money, DIar is worth considering. Although the clinic is low-key, its technology and services are of high quality. Coupled with the discount codes offered by BeautsGO and the Chinese-speaking customer service support, the entire process from booking to receiving treatment is very smooth.
