👩⚕️ Is it really difficult to make an appointment with Director Kim Jae-lin? A detailed analysis of the scheduling system.
Dean Kim Jae-lin graduated from the prestigious Yonsei University School of Medicine in South Korea. He is highly renowned on platforms such as PTT and Dcard for his anatomical-based diagnostic approach and his customized “reverse aging” treatment philosophy.
Precisely because she sees a high number of patients in person and refuses to follow a standardized treatment process, her outpatient appointments are always in high demand. If you wish to schedule an appointment with the director, we strongly recommend that you submit your request to the customer service via s-sourire as soon as you have confirmed your travel plans. During peak periods, such as on Saturday afternoons, slots are usually filled up a month in advance. However, if you avoid these busy days, it is still possible to make an appointment with the director on weekdays – early planning is the key.

🗓️ My first trip to Korea for medical beauty treatments: How to schedule Day 1, Day 2, and Day 3 in the most efficient way?
When planning a self-guided trip, the arrangement of medical beauty appointments is of utmost importance. You may refer to the following recommendations based on actual experiences shared by netizens:
| Itinerary arrangement | Recommendation rating | Reason for the Decision (Why): Why is it arranged in this way? |
|---|---|---|
| Day 1 (On the day of arrival in Korea) | ❌ Not recommended | High risks: There are numerous uncontrollable factors such as flight delays and traffic congestion in Seoul. If the delay exceeds 15 minutes, the reservation will be automatically cancelled, and it will not be possible to add a name to the queue on the same day. |
| Day 2 (Mid-journey) | ⭐⭐⭐⭐⭐ Highly recommended | Best stability: The risks associated with flight schedules and time differences have passed, and the stress of returning home has not yet set in. With sufficient time at your disposal, you can enjoy delicious food in the evening after undergoing advanced photoelectric lifting treatments, ensuring that your skin remains in the most stable condition the following day. |
| Day 3 (Midway of the Journey) | ⭐⭐⭐⭐ Highly recommended | Fairly flexible: Suitable for travelers who have already planned their itinerary, but it’s important not to rush too much, so as not to miss out on reservations at the Michelin-starred restaurants scheduled later in the trip. |
| On the day of returning to the country | ❌ Highly not recommended | High stress: If there is even a slight delay in the treatment process, or if there is some swelling after the surgery that requires ice application, there is a significant risk of missing the flight at the last minute. |

🚕 How to get to RETOO Clinic if you live in Myeongdong, Hongdae, or Apgujeong? (Time-line-based decision-making)
Clinic Address: 5th & 6th Floors, First Light Tower, 417 Dosan-daero, Gangnam-gu, Seoul (5th & 6th Floors, First Light Tower, 417 Dosan-daero, Gangnam-gu, Seoul)
| Departure location | Modes of transportation | It is recommended to plan your departure time accordingly. | Reason for the decision: Why choose this approach? |
|---|---|---|---|
| Set off from Myeongdong | Subway: Line 4 → Line 5 → Suin-Bundang Line | 70 minutes before the scheduled time | Avoid this at all costs: Taking a taxi across the river in the afternoon is extremely likely to result in severe traffic jams. The correct route is to take the subway Line 4 to [Dongdaemun Historical and Cultural Park Station], then transfer to Line 5 and get off at [Wansili Station]. From there, take the Suin-Bundang Line directly to Exit 4 of [Apgujeong Rodaero Station], and it takes about 7-10 minutes on foot or approximately 40 minutes by bus. |
| Set off from Hongdae | Subway: Line 2 → Suin-Bundang Line | 80 minutes before the scheduled time | Hongdae is located on the western side of Seoul, and it takes approximately 60 minutes to get there by subway. If you have scheduled a consultation in the afternoon, it is recommended to set off before noon to avoid potential traffic congestion in the center of Seoul. |
| Set off from Apgujeong | Subway: Suin-Bundang Line | 30 minutes before the scheduled time | Being the closest to Cheongdam-dong, it only takes two stops on the subway to reach the Apgujeong Roda Station, ensuring minimal traffic congestion. |
(Note: Upon arriving at the building, please take the elevator directly to the reception areas on floors 5 or 6 to register.)
🚫 The 5 things that most people regret the most about using Dcard/PTT
- I thought being 10 minutes late wouldn’t be a problem… But in reality, if the delay exceeds 15 minutes, the system will automatically cancel the appointment, and no exceptions are made on-site.
- On the first day upon arriving in Seoul: The flight delay, combined with the long queues at the immigration checkpoint, resulted in the cancellation of my reservation.
- Some people think that hot magpie treatments can be added on-site at will. However, for large-scale projects, if someone decides to add such treatments temporarily on-site, the receptionist will politely refuse the request.
- The schedule is too tight: It is necessary to reserve at least 3 hours for the treatment, otherwise, you won’t have enough time to get a table at the Michelin-starred restaurant afterward.
- Making a reservation just one week before departure: During the peak season, all slots are booked, and it’s a pity that we couldn’t secure a place due to this. Director Jin Zailin must have felt disappointed.
💡 FAQ: Common Questions About Rescheduling at RETOO Clinic
Q1: I have already booked my flight and will be departing next week. Is it still possible to schedule a meeting with Director Kim Jae-lin?
A: The difficulty is quite high. The only available time slots next week are during the less busy daytime hours on weekdays, while the evening appointments on Saturdays or Thursdays are already fully booked. It is recommended to immediately check via WeChat at s-sourire to see if there are any last-minute cancellations.
Q2: Which is harder to get a reservation for – Saturday mornings or Thursday evenings?
A: Saturday throughout the day is the most difficult time to get a reservation, followed by Thursday evening appointments. If you can only choose between these two periods, it is recommended to try for the Thursday evening appointment, as the success rate is slightly higher.
Q3: If I can only spare half a day, is it still worth booking a RETOO appointment?
A: It’s worth it. As long as you avoid Day 1 and the day of your return home, and choose the morning hours on Day 2 or Day 3, combined with using the subway for transportation, the time schedule can be perfectly managed.
Q4: I live in Hongdae. If I make an appointment at 14:00, what is the latest time I can leave home?
A: It is highly recommended to leave no later than 12:40. Since the subway ride from Hongdae to Apgujeong’s Roda Station takes approximately 60 minutes, and additional time is needed for walking and checking in, it is essential to allow enough time to ensure everything goes smoothly.
Q5: For my first Thermage treatment in Korea, should I schedule it on Day 2 or Day 3?
A: It is highly recommended to schedule it on Day 2. This way, if the face is a bit swollen on the first day after the procedure (Day 3), there will still be enough time for ice compresses and rest, which will not affect your mood when returning home.
Q6: If something unexpected comes up after making a reservation, is it possible to change the time?
A: Sure, but it is recommended to notify us 48 hours in advance via WeChat at s-sourire. Otherwise, it will be very difficult to secure the same schedule again during peak periods if the reservation is cancelled.

Overall evaluation: Is RETOO worth including in Seoul’s list of medical beauty services?
If you are comparing RETOO, HANMIIN, Wellderma, and other Dermatology clinics in Gangnam, RETOO’s core strength lies in integrating the decision-making logic of its director into all its processes, rather than relying solely on fixed packages.
| Evaluation criteria | Score | Key reasons |
|---|---|---|
| The expertise of the hospital director | 9.3/10 | Director Kim Jae-lin conducts very thorough consultations and customizes treatment plans based on the individual causes of aging—such as bone loss, fat accumulation, or collagen depletion. |
| Chinese friendliness index | 9.0/10 | We provide one-on-one Chinese interpretation throughout the entire process – from helping you fill out the initial consultation form and translating during the in-person appointment to providing post-operative health education, ensuring that there are no language barriers at all. |
| Convenience of making appointments | 8.8/10 | Through the s-sourire system, it’s possible to make arrangements smoothly, but the consultation hours during weekdays and on Thursday evenings with Director Kim Jae-lin are extremely popular, so it’s necessary to reserve a spot in advance. |
| Naturalness in performance | 9.1/10 | Emphasizing individual uniqueness and adopting a “pseudo-retractive” anti-aging approach, this method helps to avoid the artificial look often associated with excessive filler injections. |
| Clarity after the procedure | 9.0/10 | The health and beauty education content is comprehensive, covering details such as sun protection and skincare routines. After the procedure, users can also monitor their recovery progress at any time through WeChat. |
✅ The right candidates for RETOO Clinic
- Those who value the director’s assessment and prefer not to simply follow a preset treatment plan, but instead want to understand the underlying causes of aging before making any decisions.
- Preference for a natural look: People seek gentle, gradual improvements rather than dramatic, instant transformations.
- Seoul regulars: Those who need Chinese assistance and have a basic understanding of hospitals in the Gangnam area.
- Clear goals: People who wish to improve their jawline, Double Chin, Pores, or fine lines.
❌ Not suitable for those who visit RETOO Clinic
- Extreme price orientation: Those who primarily seek the lowest prices in the market.
- Those who pursue extreme speed: people who hope to complete the injection and all related procedures in a very short time.
- Those who expect rapid changes: people who hope to see significant improvements immediately.
If you value the symmetry of information before and after treatment and are looking to address issues such as the lower jaw line, skin laxity, or dullness, RETOO Clinic is a highly worthwhile option in the Gangnam area. Director Kim Jae-lin’s schedule is as crowded as Seoul’s subway system—if you miss one appointment, you’ll have to wait a long time for the next one. It is recommended that you confirm your travel schedule and specific needs to Korea in advance.
