To be honest, when I first considered going to South Korea for medical aesthetics treatments, I only dared to visit those few streets in Gangnam – after all, those areas are where the top-tier clinics are concentrated, easy to find, and have numerous reviews on Google. But this time, a friend took me to the newlline Dermatology clinic in Seongsu, and it truly changed my understanding of the “medical aesthetics landscape in Seoul”.
In recent years, Seongsu-dong has become increasingly popular. From cafes and boutiques to restaurants, it has evolved into Seoul’s most vibrant and culturally rich area for intellectuals. The newlline clinic is located right in this bustling district – just 1 minute’s walk from Exit 5 of Dodog Island Station, so you don’t have to contend with the crowds in Gangnam at all.
I. What is the Dermatology department at Seongsu newlline? Why is it even more worth considering than those in Gangnam?
The newlline clinic (뉴엘라인의원) is a Dermatology practice located in Seongsu-dong, Seoul. The director of the clinic is Dr. Lee Eun-sil (이은실). The name of the clinic is inspired by the term “New Line,” which signifies the creation of a completely new silhouette.
Unlike those popular clinics in Gangnam that always have long queues, newlline takes a different approach—focusing on high-quality consultations rather than maximizing the number of clients. A friend told me that when she went for a consultation, the director spent nearly 30 minutes explaining in detail the areas of her face where there was sagging, before suggesting which treatments would be suitable for her. Such a level of attention is truly rare at the large chain clinics in Gangnam.
Its main strengths lie in Lifting treatments – Ulthera ultrasound therapy, Thermage FLX, Shurink Universe, Corage 2.0 egg-shaped Lifting, and Thread Lifting. Basically, any well-known Lifting treatment is available here. In addition, Potenza Potenza, PRP (Platelet-Rich Plasma) regeneration injections, and Filler injections are also very popular services.
II. Where is newlline located? Seongsu-dong is extremely accessible, just 1 minute away from Dodo Island Station.
The address is 5th floor, 26 Sangwon-gil, Seongdong-gu, Seoul (서울 성동구 상원길 26, 5층). Take the subway Line 2 to Ttukseom Station, exit at Exit 5, and then walk straight ahead for about 1 minute – it’s very easy to find.
If you have a plan to visit cafes in the Seongsu area, such as those around Blue Bottle in Seongsu or Daelim Warehouse, it’s really convenient to take the opportunity to get a consultation or receive a treatment on the way – it saves you the time needed to travel to Gangnam.
Here is some additional information about the business hours:
- Monday to Thursday: 11:00 – 20:00
- Friday: 11:00 – 21:00 (Night clinic available!)
- Saturday: 11:00 – 16:00
- Lunch Break: 14:00 – 15:00 (every day)
- Sunday: Rest day
It’s really considerate that it’s open until 9 p.m. on Fridays. People who are working or have busy travel schedules don’t need to take special leave; they can just come here right after visiting Seongsu Cave in the afternoon.
III. Introduction to newlline’s popular products: Ultrasound Knife, Thermage FLX, and Potenza Potenza
The Lifting programs offered by newlline clinic are very comprehensive, and the following ones are particularly popular among Taiwanese customers:
🔥 Ulthera HIFU Device (American version of the HIFU system)
Genuine Ulthera equipment, not a counterfeit. This technology uses focused ultrasonic waves to stimulate the SMAS fascia layer, effectively lifting the facial contours from within. The results generally last for 12 to 18 months. Many people report that their face shape becomes noticeably more defined, with a V-shaped contour, making it particularly suitable for those who have sagging skin around the jawline or on the lower cheeks.
The reference prices currently available on BeautsGO start from ⩩990,000.
✨ Thermage FLX Thermage
The latest generation of Thermage FLX features an upgraded treatment head that is more comfortable to use and provides more even coverage. The radiofrequency energy heats the dermis, promoting the production of new Collagen and helping to reduce facial sagging. It is particularly effective in addressing issues such as sagging Apple Zone and Nasolabial Fold Correction.
🌟 Potenza Potenza
The first choice for issues such as enlarged Pores, acne scars, and uneven skin texture. The gold-coated needle, combined with radiofrequency energy, precisely penetrates the dermis with virtually no pain, and the recovery time after the procedure is also very fast (usually 3-5 days). It is highly effective in addressing mild skin laxity and other skin-related problems in just one treatment.
💉 Filler injections & Botox
Common treatments such as Nasolabial Fold Correction, Tear trough correction, temple filler injections, as well as procedures for a smaller face shape, eye corner lifting, and Forehead smoothing are all available. The clinic director will recommend the appropriate amount of filler based on the proportions of your face, ensuring that you do not receive excessive injections just to meet performance targets.
IV. How does Director Li Enshi manage to retain local customers?
Director Lee Eun-sil is a specialist in Dermatology, specializing in Lifting of facial contours and skin regeneration. A friend told me that what she likes most about Director Lee is that every time she goes for a consultation, it feels more like a friendly conversation rather than a sales pitch. Director Lee will ask her about her daily routine and the condition of her skin, instead of immediately suggesting how many injections are needed in certain areas or how many treatment sessions are required.
In addition, the clinic has a very good reputation among local residents in Seongsu-dong – many of its patients are repeat customers, or people who are recommended by their friends. This kind of word-of-mouth trust is actually much more convincing than any form of advertising.
V. What is the environment like at the newlline clinic? Let’s take a look through pictures and text.
The clinic is located on the 5th floor, and upon entering the elevator, you’ll immediately come across a simple and elegant reception area. The overall design leans towards a understated, high-quality aesthetic – nothing too flashy or marble-surfaced like what’s commonly seen in popular internet cafes. Instead, it features soft beige tones and decorative plant elements, creating a very relaxing atmosphere where you won’t feel any sense of pressure.
The consultation room is separated from the treatment room, and privacy protection is quite good. The equipment in the treatment room looks very new – the Ulthera machines are accompanied by original labels (in many places, imitation products are often used instead); this detail really reassured me.

VI. FAQ on Common Issues Related to newlline
Q1: Does the clinic offer services in both Chinese and English? Is there any issue with langua
ge communication? Although the clinic is primarily designed for Korean-speaking patients, its official website provides a Chinese version, and it is also listed on BeautsGO, which offers a Chinese-language interface. If you make an appointment through BeautsGO, the platform will facilitate communication in Chinese. For oral consultations, it is recommended to bring a friend who understands Korean, or prepare the consultation questions in Korean in advance using translation software. The director is very patient.
Q2: What is the difference between Ulthera and Shurink Universe? Both are ultrasonic Lifting devices, but Ulthera is a genuine ultrasonic device certifi
ed by the US FDA and belongs to the medical grade category. It offers a variety of probes that can reach different depths, making it suitable for those with significant signs of skin laxity. Shurink Universe, on the other hand, is a South Korean-made ultrasonic Lifting device with a more affordable price and milder post-treatment effects, making it ideal for maintenance treatments or mild skin tightening. If this is your first time trying such a treatment, it is recommended that you consult with the clinic director to get personalized recommendations based on your specific needs.
Q3: How long does it take to see the results after undergoing ultrasonic knife treatment? What precautions should be taken after the procedure? Th
e effects of ultrasonic knife treatment usually begin to appear around 1 month after the procedure and reach their peak around 3 months. Immediately after the treatment, there may be mild swelling or discomfort, which are normal reactions and will generally subside within 1 to 3 days. It is recommended to avoid saunas and high-temperature environments for at least 1 week after the procedure, and it is also not advisable to undergo any other heat-based treatments immediately afterwards.
Q4: Is it possible to have an initial online consultation in Taiwan or Hong Kong before proceeding with the treatment in
South Korea? Yes, that is possible. It is recommended to make a reservation through BeautsGO and indicate that you are making a reservation from overseas. The clinic will usually arrange a preliminary consultation via phone or video call to assess your skin condition and determine the treatments you would like to undergo. This will save you time waiting on-site after you arrive in South Korea.
Q5: What are the payment methods available? Can I use a credit card? Gen
erally, Dermatology clinics in South Korea accept both South Korean won in cash (₩) and Visa/Mastercard credit cards; however, some clinics do not accept American Express. It is recommended to confirm the payment methods in advance before making an appointment. You can also consult BeautsGO for more information on payment options, or indicate your preferred payment method in the reservation notes.
Q6: The evening clinic on Friday lasts until 21:00 – what treatments are suitable during this time? P
rocedures such as ultrasonic knife treatment or Potenza Potenza treatment, which require some rest after the procedure, are recommended to be scheduled before returning to the hotel (to avoid further shopping). For treatments like Filler injections or botulinum toxin injections, which do not affect daily activities, the evening clinic is also an option. If you come on Friday evening, please note that there will be no consultations from 14:00 to 15:00; it is therefore most convenient to schedule your appointment after 15:00.
