Who is Dr. Lee Eun-sil, the director of Seongsu Newlline Dermatology? Learn about her qualifications and the in-person consultation system in one go.
Profile of Dr. Li En-shi at Newlline: Family medicine specialization + expertise in various medical devices, KeyDoctor
👩⚕️
Let’s get to the bottom line first: Director Lee Eun-sil is a Dermatology specialist with a background in family medicine. According to BeautsGO’s facility profile, she holds the title of KeyDoctor for multiple treatment devices—meaning she has received official certification training from the manufacturers for those devices, and isn’t just someone who operates them by following the instruction manual.
Why is it worth mentioning that a doctor has a background in family medicine? That’s because training in family medicine in South Korea already covers comprehensive health management for the whole body. When transitioning into the field of skin anti-aging, such doctors tend to be more cautious about “assessing a patient’s physical condition before treatment” compared to those with purely cosmetic medical backgrounds—they take into account factors like sleep patterns, allergy history, and medication habits during the consultation. For foreign tourists doing medical aesthetics treatments in South Korea for the first time and worried about potential communication gaps, this type of assessment-based consultation approach is quite reassuring.
One more thing to keep in mind: although the BeautsGO hospital page lists several doctors, its official description clearly states that “all procedures are performed exclusively by Director Lee Eun-sil” — meaning the person you meet in person is also the one who performs the treatment. To confirm whether the procedure will indeed be done by the director on your chosen date, it’s best to verify this directly with the Chinese-speaking customer service team when making your appointment.
What is the single-director system? The in-person consultation approach and no-sales culture at Seongsu Newlline Dermatology
🏥
The “single-director system” simply means that one director is responsible for making all medical decisions at a clinic—there are no shift rotations, so it’s not the doctor A one day and doctor B the next. The advantage is consistent treatment standards and coherent aesthetic outcomes, but the downside is limited availability for appointments. The clinic itself advises patients to schedule appointments outside peak hours, which is actually an inevitable consequence of this single-director system.
Based on actual customer feedback, the experience this system offers is quite distinct: some clients mentioned that doctors would simply say, “You can do this treatment next time—there’s no need to rush.” In an industry where additional services are constantly pushed upon customers, such attitude actually wins them over the most. Waiting times start around 40 minutes, and the clinic director will proactively inform patients when their follow-up appointment is scheduled. The pace here is more relaxed, rather than following a high-speed assembly-line approach.
If all you care about is “speed” and “low cost,” a single-physician clinic might not be the best choice. But if you’re concerned about “who will perform the procedure, how well it will be done, and who will be responsible afterward,” this type of one-physician clinic offers the clearest line of accountability.
The equipment lineup at Seongsu Newlline Dermatology: Volnewmer, HIFU, and Shurink
🪄
The equipment list offered by Newlline is quite comprehensive in the Seongsu Cave area. Below are four of their flagship machines as described by the official source:
- Volnewmer (Golden Birch, Oligio): It uses monopolar radiofrequency combined with a water-cooling system, and is marketed as causing less pain without the need for anesthesia, making it particularly suitable for Asians with thinner and more sensitive skin.
- Ulthera HIFU: The clinic is currently using the first-generation model, with the second generation already ordered and expected to arrive soon. It targets the SMAS fascia layer, and according to the manufacturer, its effects last around 1 year (though this may vary from person to person).
- Corage 2.0: A non-high-temperature, non-thermal damage approach that uses resonant energy to awaken cells, offering a powerful combination of Lifting, repair, and barrier strengthening.
- Shurink / Shurink Universe: The flagship Korean version of HIFU, offering excellent value for money with minimal discomfort—ideal for customers who need regular maintenance treatments.
It’s important to note that having a large variety of devices doesn’t mean every one of them is suitable for you. Under the hospital’s single-director system, the director will recommend specific device combinations based on your skin condition during the consultation, rather than pushing products according to the price list—this is also confirmed by the consistent positive feedback regarding “no aggressive selling” in customer reviews. For discounted prices on these devices, you can check the Newlline promotional price table available on the website, which is updated monthly.

First-hand Look at the Layout and Flow on the 5th Floor of MILK Building in Seongsu-dong
🫧
Located on the 5th floor of the MILK building in Seongsu-dong (address: 26 Sangwon-ro, Seongdong-gu, Seoul), Newlline occupies an entire floor for exclusive use and features 6 assistants. Judging from the actual photos, the interior adopts a minimalist style with off-white tones: the waiting area is adorned with artistic paintings and display cabinets filled with skincare products, making patients feel more like they’re browsing through a quiet boutique rather than waiting in line for surgery.
The procedure flow is as follows: registration at the front desk (you can show your BeautsGO appointment record) → free skin assessment → consultation with the clinic director → treatment → explanation of the post-treatment care plan. What’s been mentioned most frequently in customer reviews is the “thorough skin assessment right upon entry” — instead of immediately pushing treatment options, they first examine the data before discussing possible procedures, which is particularly important for those trying medical aesthetics for the first time.
Guide to Transportation and Business Hours at Seongsu Newlline Dermatology
📍
For transportation, take the subway to Seongsu Station and exit through Exit 5. Head straight into the Seongsu-dong shopping area, and you’ll reach the MILK building in just a short walk. Over the past couple of years, Seongsu-dong has become a popular weekend spot for Seoul’s youth thanks to its array of trendy brand flagship stores and cafes. Incorporating skin care treatments into your shopping itinerary is no problem at all.
- Monday to Thursday: 11:00–20:00
- Friday: 11:00–21:00 (night clinic – perfect for a visit after work)
- Saturday: 11:00–16:00
- Lunch break: 14:00–15:00 daily
- Sunday and public holidays in South Korea: closed
Two things to keep in mind: first, avoid scheduling appointments during lunchtime (14:00–15:00). Second, clinics in South Korea often close temporarily during holidays such as Chuseok, Gaecheonjeol, and the National Day holiday period. Make sure to check the clinic’s operating status for that week through BeautsGO’s Chinese customer service before planning your trip. There are plenty of accommodation options in the area—customers have mentioned in their reviews that “there are many hotels nearby, making it convenient to stay.” HOTEL POCO is about 761 meters away, so you can walk back there at night.

Real Reviews of Seongsu Newlline Dermatology: Translation Services, Wait Time, and Follow-up Appointments
⭐
Organize the feedback from foreign customers on the BeautsGO page and Google reviews into three categories, clearly outlining both the advantages and disadvantages.
- Communication Experience: Full-time interpretation in Chinese is the top-rated advantage, with many reviews mentioning “zero communication barriers” and “useful suggestions”.
- Pace management: You’ll wait around 40 minutes before the procedure starts. The doctor will proactively say, “You can do this treatment another time; there’s no need to rush.” The room supervisor will inform you in advance about the follow-up appointment time—this is a situation with a slower pace but clear communication.
- Post-surgery follow-up: You’ll receive a detailed care checklist before leaving the clinic, along with tips on skincare; the downside is that under the single-director system, it’s difficult to schedule appointments during peak seasons, and there’s little flexibility for last-minute changes.
Overall, no negative keywords such as “pushy sales,” “overcharging,” or “poor attitude” appeared in the reviews. The most frequently mentioned traits were “patience,” “carefulness,” and “no rush.” If you want to see more discussions about potential issues and authenticity, this well-received Dcard review of Newlline on the site covers all the key concerns people have—especially regarding price and legitimacy.
