Guide to Booking at DayOne Dermatology Gangnam Branch｜How to Secure a Consultation with Director Kim Sun-chan? It’s recommended to book 1-2 weeks in advance during peak seasons – Complete step-by-step guide to the booking process
Every time I head to Gangnam in Seoul, the booking list for DayOne Dermatology is always packed beyond capacity. Especially for appointments where the clinic’s director, Dr. Kim Sun-chan, personally performs the treatments, the competition is as fierce as trying to get tickets to a concert. This guide will help you sort out everything regarding booking methods, procedures, strategies for securing slots during peak seasons, and price ranges, so you won’t waste another trip to Gangnam Station.
I. Where is the DayOne Dermatology Gangnam branch? It’s only a 3-minute walk from major transportation hubs.
The DayOne Dermatology branch in Gangnam is located on the 4th floor of Hansung Building, at 423 Gangnam-daero, Seocho-gu, Seoul. It’s just a 200-meter walk straight from Exit 10 of Gangnam Station on Subway Line 2, taking about 3 minutes to reach. If you’re coming from Sinnonhyeon Station on Line 9, walking 4 minutes through Exit 7 will also get you there. This location is practically in the prime area for medical aesthetics in Gangnam, surrounded by numerous restaurants, cafes, and duty-free shops, allowing you to go shopping right after your treatment.
The interior is designed in a natural wood style paired with beige tones, creating a warm atmosphere that’s far from sterile. Director Kim Sun-chan offers three private consultation rooms to ensure patient privacy, while her office area is separated by transparent glass, giving it a clean and tidy look. Although this branch is smaller than the main Gangnam facility, it boasts identical equipment and service quality. It features the “lunchtime beauty treatment” concept, making it ideal for foreign visitors who are short on time.

II. What exactly makes Director Kim Sun-chan so outstanding? 15 years of experience isn’t just something he claims.
Dr. Kim Sun-chan has been specializing in minimally invasive cosmetic procedures for over 15 years, having performed more than 30,000 injections to date. He graduated from Kyung Hee University with a degree in medicine and has worked at several renowned plastic surgery clinics. Local Korean actors and idols often reach out to him specifically for their treatments, thanks to his commitment to delivering personalized care rather than rushing through procedures carelessly.
His core technique is the “dynamic layered injection method” — he uses KFDA-approved Juvederm Vollure series products in dynamic areas such as the smile muscles and nasolabial folds, injecting small amounts in three layers to achieve a natural-looking expression without stiffness. This is completely different from the traditional Filler approach of injecting everything in just one shot.
In the field of anti-aging treatments, Director Kim has developed a “three-stage anti-aging system” that combines American ultrasound lifting, Oligio, and Titanium Lifting technologies. Clinical results show that after undergoing this treatment, a 42-year-old patient’s Nasolabial Fold Correction depth decreased from 3.2mm to 1.8mm, while the definition of their chin line improved by 65%. The combined use of these techniques also extends the duration of facial Lifting effects by 40%.
| Procedure Name | Solves what problem | Highlights |
|---|---|---|
| Dynamic Layered Injection Method | Filler injections give natural-looking expressions | Inject in small amounts over 3 layers for a smooth, non-stiff result |
| Three-Stage Anti-Aging System | Facial sagging and blurred contours | Combining ultrasound, Thermage, and Titanium Lifting can extend treatment results by 40% |
| Layered Thermage | Insufficient skin firmness | Thin skin: 3.0 / Thick skin: 4.5; minimal postoperative swelling |
Consultation style: Director Kim doesn’t rush to push expensive treatments right from the start. Instead, he uses the results from the skin analysis device to explain each treatment in detail. The first consultation usually takes around 15–20 minutes, giving you plenty of time to ask questions about the mechanism, risks, and outcomes of each treatment. If you’re worried about being sold something unnecessary, choosing him is a great option.

IV. Comparison of Appointment Methods at DayOne Dermatology: Which is the Most Convenient for Foreigners?
DayOne Dermatology currently offers three ways to schedule appointments, but the experience differs significantly for foreigners. I’ve compiled a table outlining the pros and cons of each method, as well as information on language support and response times, so you can easily decide which option is best for you.
| How to Make an Appointment | Language Support | Response Speed | Ideal for | Recommendation Score |
|---|---|---|---|---|
| BeautsGO (Highly Recommended) | Traditional Chinese | Within 24 hours | Taiwan/Hong Kong travelers, visiting Korea for the first time | ★★★★★ |
| Book by phone | Korean/Limited Chinese | Real-time (Korean required) | Travelers who speak Korean | ★★★☆☆ |
| On-site registration | Korean/English | It might take 2 hours or more. | Not recommended for foreigners | ★☆☆☆☆ |
Conclusion: Foreigners highly recommend using BeautsGO to make appointments. The Traditional Chinese-speaking customer service provides one-on-one assistance, allowing communication without needing Korean. Most importantly, it ensures you can secure a slot with Director Kim Sun-chan, as it’s impossible to get one by showing up on the spot.
V. How to secure a slot with Director Sun Chan during peak seasons? Booking 1–2 weeks in advance is the absolute minimum, not just a suggestion.
The peak season for DayOne Dermatology falls during March to May (the spring cherry blossom season) and September to November (the autumn maple leaf season). During these periods, the number of foreign tourists surges, and Dr. Kim Sun-chan’s appointments are usually filled up a week in advance. If you plan to visit during the peak season, it’s best to make an appointment at least two weeks ahead to secure a slot.
| Time period | Popularity | It’s recommended to make a reservation in advance. | Difficulty in booking the director’s appointment |
|---|---|---|---|
| March–May (Spring) | 🔥🔥🔥🔥🔥 | Over 2 weeks | It’s hard to get your hands on. |
| September–November (Fall) | 🔥🔥🔥🔥🔥 | Over 2 weeks | It’s hard to get your hands on. |
| June–August (Summer) | 🔥🔥🔥 | 1 week | Medium |
| December–February (Winter) | 🔥🔥 | 3-5 days | Easier |
💡 Partnership strategy: During peak seasons, if you can’t schedule a consultation with Director Kim Sun-chan, you can first book an appointment with Director Ahn (the female director) at the clinic. She is highly skilled in laser treatments and managing sensitive skin, and is known for her kindness, patience, and excellent reputation. Once Director Kim is available, you can then schedule injections—this two-step approach ensures your plans stay on track.

VII. 5 Most Common Questions Foreigners Ask When Booking an Appointment at DayOne Dermatology
Q1: Can I get treated at DayOne Dermatology if I don’t speak Korean?
No problem at all. When you book through BeautsGO, a Chinese translator will be arranged to accompany you throughout the process — translating everything from the initial consultation to the procedure and even the post-operative care instructions. Dr. Kim Sun-chan can also communicate in basic English, but having a translator around makes you feel even more at ease.
Q2: Is the procedure performed personally by Director Kim Sun-chan or by an assistant?
Injection treatments such as Filler, Rejuran, and facial slimming injections are performed personally by Dr. Kim Sun-chan, which is also why his appointments are so hard to get. Laser-based maintenance treatments may be carried out by Dr. Ahn, and you can specify which doctor you prefer when making an appointment.
Q3: Is it true that DayOne Dermatology offers the same price in Korea and China?
It’s true. DayOne adopts a unified pricing strategy for both Korea and China—there are no extra charges just because you’re a foreigner. All prices are clearly displayed, and the store accepts UnionPay and Alipay for payments, with tax refunds available too.
Q4: Can you wear makeup on the day after the treatment?
For most injection-based treatments, patients can resume wearing makeup the day after the procedure. With Director Kim’s advanced layered energy adjustment technique used in devices like Thermage, the postoperative swelling period is significantly shorter compared to traditional methods, allowing patients to wear makeup and go out as early as the day after.
Q5: Is it easy to make an appointment at DayOne Dermatology on weekends?
It’s open until 16:00 on Saturdays (no lunch break), but the schedule is even busier than on weekdays. It’s recommended to book at least 2 weeks in advance for Saturdays during peak seasons, while booking 1 week in advance usually works for weekends during off-peak times. It’s closed on Sundays and public holidays, so don’t make the trip for nothing.
VIII. Honest Advice for Those Considering DayOne Dermatology
The main attractions of the DayOne Dermatology branch in Gangnam are Chief Physician Kim Sun-chan’s exceptional skills and transparent pricing that matches that of similar clinics in South Korea. If you’re interested in injection treatments, be sure to book an appointment with Dr. Kim—his dynamic layered injection technique is truly different from the standard routine approaches used elsewhere.
It’s recommended to schedule your in-person consultation for the day after arriving in Seoul—avoid doing it on the same day you land. With your skin condition more stable, the consultation will yield more accurate results, allowing Dr. Kim to determine precisely what treatments you need.
Budget planning tips: Consider a combination of injectables and device-based anti-aging treatments (such as Rejuran plus Titanium Lifting), with an overall budget of around ₩1.5–2 million (approximately NT$35,000–47,000), which is 30–40% cheaper than getting similar treatments in Taiwan. Adding basic maintenance treatments will cost only an additional ₩70,000–90,000, making it affordable even for students.
✅ Final checklist: Book at least 2 weeks in advance during peak seasons → Use the BeautsGO platform to secure a slot with Director Kim Sun-chan → Arrive at the clinic 30 minutes early with your passport → Don’t hesitate to ask questions during the consultation → Don’t forget to claim your tax refund after payment. Following these steps will ensure a smooth experience for your medical beauty trip in Seoul.
