Are the prices at Seongsu Newlline Dermatology really that low? Are there any hidden costs involved?

💰

The answer is: It’s really cheap, and the pricing is transparent, with no hidden costs. The term most frequently searched on Google is “Newlline prices”, and this is precisely why Seongsu Newlline has become so popular among the Taiwanese community – its prices are 20-30% lower than those of similar clinics in the Gangnam area. However, the word “cheap” can raise concerns for many people: Could the equipment not be genuine? Could the medications be diluted? Would additional services be tried to sell after the treatment? Let’s analyze these points one by one.

Newlline’s pricing model has several key features:

1. ILCHI prices for both China and South Korea: Foreigners are not charged any extra fees, and the prices listed on the official website and in the BeautsGO APP are the same for everyone. This point has also been confirmed by reviews from South Korean locals on Naver, indicating that there is no distinction between “tourist prices” and “local prices”.
2. Transparent pricing – Unlike many clinics that simply state “Please consult”, the prices of Newlline’s services can be directly checked on the BeautsGO APP, allowing you to plan your budget in advance before making a decision.
3. No reservation fees, no consultation charges – you don’t need to pay in advance to make a reservation. You can come for a face-to-face consultation on-site and decide whether to proceed or not. For those who are still hesitating, there is absolutely no pressure at all.
4. Some packages offer discounts – for example, the hyaluronic acid injection package is available at a reduced price for multiple treatments, making it more cost-effective for customers who plan to receive multiple sessions.

For example, taking the actual prices as a reference: The Rejuran PN costs approximately 912,100 Korean won (about NT$2,700), while similar treatments at clinics in Gangnam usually start from 918,000 to 220,000 Korean won. The Thermage FLX with 600 treatments costs around 9.16 million Korean won (about NT$36,000), which is also about 30% cheaper than in Gangnam. It should be noted, however, that the cost of sedation anesthesia is additional and amounts to 925,000 Korean won (about NT$5,600). This fee is not included in the initial treatment quote. If you choose a procedure that requires anesthesia, such as Thermage FLX, this additional cost must be taken into account when calculating the total budget.

Are the equipment and doctors at Seongsu Newlline Dermatology truly legitimate? Are their qualifications up to par?

🏥

The answer is: All equipment is genuine; the doctors have over 15 years of experience; and the procedures are performed personally by the hospital director. This is the second most frequently asked question on Google. Especially when the price seems low, many people worry that “you get what you pay for” – but the reason why Newlline offers such affordable prices is not due to any cutbacks in quality or materials, but rather due to its unique business model.

Firstly, in terms of equipment, the instruments used by Newlline include:

• Thermage FLX (US version) – This is not the Korean or Chinese version, but an original import from Solta Medical. Its authenticity can be verified using the original product serial number.
• Ulthera HIFU (US version) – Also imported directly from the manufacturer; it is neither a copy nor a modified model.
• Volnewmer is a South Korean brand that specializes in producing legitimate medical devices, used as an adjunct to anti-aging treatments following Thermage procedures.

The authenticity of these devices can be verified on the official websites of the manufacturers to determine whether a clinic is an authorized user. As a Key Doctor partner clinic of several equipment manufacturers, Newlline can assure you that the legitimacy of its equipment is beyond doubt – in fact, manufacturers conduct more stringent inspections on the equipment in Key Doctor clinics than on those in ordinary clinics, because Key Doctor represents the official endorsement of the brand.

Let’s talk about the doctors. Director Li Enshi was originally a specialist in family medicine but later focused on the field of cosmetic dermatology for over 15 years. She also holds the title of “Key Doctor” for several international medical beauty equipment brands, which signifies that she is not only a user of these products but also provides training for other doctors on their operation. For a doctor to be selected as a Key Doctor by a manufacturer is in itself a testament to their technical expertise in the industry.

What reassures Taiwanese customers the most is Newlline’s system of having a single director in charge of all procedures. All photorejuvenation and injection treatments are performed personally by Director Lee Eun-sil. There is no such situation where “the consultation is conducted by the director, but the actual treatment is carried out by an intern.” This is actually quite rare in South Korea’s medical aesthetics industry; most clinics operate on a shift-based system, so you may encounter different practitioners each time you visit.

To be honest, this is also one of the reasons why the prices can be kept low: by having only one director in charge, the operating costs are lower than those of a clinic with multiple doctors. The savings are then reflected in the prices. Simply put, almost all the money you pay at Newlline is directly used for the director and the equipment, rather than supporting a large administrative and management staff.

What are the effects of Seongsu Newlline Dermatology? How long do they last? Are there any cases of failure?

✨

The answer is: The results follow a natural course, and no obvious failure cases have been found on Google or Naver. However, whether the results are satisfactory is highly subjective and depends on the aesthetic standards you pursue. Newlline’s style embodies a natural Korean aesthetic – it doesn’t involve those obvious changes that make it immediately clear that “some cosmetic procedures were done”.

Effect timeline (taking the combination of Thermage + Volnewmer as an example):

• Immediately after the procedure: The skin felt slightly tight, and the contours of the jawline began to become visible; there were already noticeable changes when taking photos from the side.
• 1–3 days after the procedure: The mild swelling subsides, and the face begins to exhibit a natural sense of lift.
• 2–4 weeks after the procedure: Collagen begins to proliferate, and the effects become increasingly noticeable. Friends start asking, “Have you lost weight recently?”
• 3 months after the procedure: The effects reach their peak, with the most noticeable improvement in skin tightness and glow.
• Duration: Thermage treatment lasts for approximately 1 year; when combined with Volnewmer, the effect can be extended to over 1 year.

Key feedback from several actual users:

• “After getting the Tear trough correction with Filler, my friend said she couldn’t tell at all that I had had the procedure done; she only mentioned that my complexion looked great lately.”
• “The jawline has really become more noticeable; I no longer need to deliberately pull in my chin when taking side photos.”
• “It’s not that kind of post-operative swelling or artificial look commonly seen among internet celebrities; it’s a very natural sense of firmness.”

However, it is important to note that if you are seeking a very noticeable V-shaped face or prominent Apple Zone in the European and American style, Newlline’s natural approach may not be suitable for you. This is also why many reviews mention that the results look “very natural” and “it’s impossible to tell that any treatment was done” – while for some people this is exactly what they desire, others may find that the effects are not “sufficiently noticeable”. It is recommended that you clearly communicate your desired level of results during the consultation, and the doctor will adjust the treatment plan according to your needs.

True feedback on the sensation of pain:

• HIFU: After applying the anesthetic, there is “almost no sensation at all”; only the areas where the bones protrude experience mild soreness and swelling, which is much more comfortable than expected.
• Thermage FLX: Equipped with an intelligent temperature control system, it is much more comfortable than the previous version, but there may still be a slight sense of heat and mild stinging.
• Rejuran injection: There is a relatively strong stinging sensation on the Forehead and nose bridge areas, while the cheeks experience only mild discomfort, still within an acceptable range.

To be honest, those who are afraid of pain are advised to start with treatments like hyaluronic acid injections or basic skin care. Once they get used to these, they can then try treatments like Thermage or HIFU. There’s no need to rush into the most painful procedures right away.

If I don’t speak Korean, can I still go to the Newlline Dermatology clinic for medical beauty treatments? Will there be any communication barriers?

📱

The answer is: There is absolutely no need to worry, as professional Chinese translators will provide one-on-one assistance throughout the entire process. This might be the issue that Taiwanese customers are most concerned about, but in fact, it is precisely the aspect that Newlline has the least reason to worry about.

Newlline’s Chinese-language services cover the following complete process:

1. Reservation phase: The BeautsGO APP features a fully Chinese-language interface, allowing users to directly select the date and time of their appointment without having to navigate Korean-language websites.
2. Fill out the form upon arrival at the clinic – Chinese-language forms are available, and both traditional Chinese and simplified Chinese versions are provided for sections such as medical history, allergy history, and detailed requirements.
3. During the consultation with the director, our professional translators will be present throughout the process to ensure that your needs are accurately conveyed and that the director’s expert advice is properly translated, avoiding any misunderstandings or awkward situations.
4. Step-by-step guide — The translation will explain what each step involves and how you will feel during the process, helping you feel more at ease in this unfamiliar medical environment.
5. Postoperative Education — The Chinese version provides detailed instructions on postoperative precautions, actively highlighting those details that are easily overlooked.
6. For follow-up support, you can contact the Chinese customer service via WeChat. Any issues that may arise after the procedure can be addressed immediately, eliminating the need to travel to South Korea again.

Many Taiwanese girls who have visited these clinics share that “from the moment you enter until you leave, there isn’t any need to speak a word of Korean at all; it’s much easier than I expected.” Some even say that “the quality of translation is sometimes even better than that of the consultants at certain Taiwanese clinics.” However, it’s important to note that during peak hours, you may need to wait a bit for a Chinese translator. If there happen to be multiple Chinese customers at the same time, the translator might have to switch between different treatment rooms. It’s recommended to avoid visiting on Friday afternoons and throughout Saturdays, as these are the times when the number of Chinese customers is at its highest, and your communication experience will be smoother accordingly.

The single-director system at Seongsu Newlline Dermatology: Is it a plus or a minus?

👭

This is perhaps the most controversial aspect of Newlline, and it is also the topic that generates the most discussions in Google reviews. To conclude: for those who value ILCHI in product quality, this is certainly a advantage; however, for those with tight schedules, more patience will be required.

The 5 major advantages of the single-department director system:

1. The quality of the services provided is always ILCHI – there will never be situations where “the previous doctor performed very well, but this time the results are much worse due to a different person performing the procedure”; every follow-up visit is always handled by the same professional.
2. The doctor will retain a permanent memory of your face – during follow-up visits, the director will remember the structure of your facial features, the location where the previous treatment was administered, and your feedback, so there is no need for further communication.
3. Eliminate the practice of “changing hands” – In many clinics, a doctor performs the procedure, only to be replaced by another doctor or even an intern. However, this situation never occurs at Newlline.
4. ILCHI in aesthetic style: Different doctors may have different aesthetic perspectives, but this will not result in inconsistent outcomes after each treatment.
5. The director has a stronger sense of responsibility – as she is the only one operating the entire clinic, its reputation directly depends on her performance, so her approach to work is naturally more meticulous.

The cost of a single-department director system:

• The number of people we can accommodate each day is limited, so you may need to wait during peak hours on weekends.
• When the director is on vacation or going abroad for further studies, the entire clinic will temporarily suspend services. It is recommended to double-check the operating status before departure.
• The most popular booking times, such as Friday afternoons and Saturday all day, tend to fill up within an hour of being made available. It is recommended to book 3 to 7 days in advance.

If you value the concept that “the same doctor will handle the entire procedure from start to finish,” Newlline’s system of having a single chief physician is a significant advantage. However, if you prefer “immediate treatment without waiting in line,” you may want to consider large clinics with multiple doctors.

🧳

Below, we have compiled all the remaining practical information in one place for easy reference before you set off.

📍 Address and Transportation:

• Address: 5th Floor, 26 Sangwon-gil, Seongdong-gu, Seoul (성동구 상원길 26, 5층)
• Subway: Take Line 2 and get off at Seongsu Station or Daodao Island Station. After exiting the station, walk for about 3 to 5 minutes.
• Surroundings: After the treatment, you can directly visit the Seongsu-dong shopping area – the Ader Error flagship store, the Dior Seongsu concept store, and Lotte Supermarket are all within walking distance.

📅 Business Hours:

• weekdays (Monday to Friday): 11:00-19:00
• Saturday: 11:00-16:00
• On Sundays and South Korea’s public holidays: closed throughout the day.

📝 How to make an appointment:

• With the BeautsGO APP, you can make reservations with just one click – its user-friendly Chinese interface makes the process extremely simple.
• It is recommended to make a reservation 3 to 7 days in advance, as weekend periods are particularly popular.
• No reservation fee required, no consultation fee either. You can decide whether to proceed with the treatment only after having a in-person consultation at the clinic.
• If you need to reschedule or cancel, please apply at least 24 hours in advance.

⚠️ Post-treatment precautions (these 5 points are the most important):

1. Avoid getting your face wet or applying makeup within 24 hours after the procedure to give your skin time to recover.
2. Avoid steam baths, saunas, and strenuous exercise within 3 days after the procedure. If you use a sweat bath in South Korea, wait until you return to Taiwan before taking a hot spring bath.
3. Avoid alcohol and spicy foods for at least 1 week after the procedure, as alcohol can exacerbate swelling and slow down recovery.
4. Sun protection is of utmost importance – after the procedure, the skin becomes more sensitive, so it is essential to apply SPF50+ sunscreen every day. The sun in South Korea is particularly intense during the summer.
5. If you experience abnormal redness, persistent pain, or a fever after the procedure, please contact our Chinese customer service immediately via WeChat. Do not endure these symptoms on your own.

Summary of the Advantages and Disadvantages of Seongsu Newlline Dermatology

⚠️

Frequently Asked Questions

Q: Is a deposit required to visit the Newlline Dermatology clinic for medical aesthetics treatments?

A: No need. Newlline does not charge a reservation fee or consultation fee; you can decide whether to proceed with the treatment only after having a face-to-face consultation on-site. However, it is recommended to make a reservation 3-7 days in advance, as popular appointment times usually fill up within an hour of opening.

Q: Can I go shopping immediately after getting cosmetic surgery? Are there any restrictions?

A: After undergoing non-invasive treatments such as Thermage or HIFU, you can resume your normal activities. However, it is recommended to avoid steam baths, saunas, and strenuous exercise for the first 3 days after the procedure. Mild redness usually subsides within 1 to 3 days, and you can apply makeup 24 hours after the treatment. Newlline is located near the Seongsu-dong shopping area; you can go shopping just a few minutes after the treatment, but don’t forget to bring sunscreen.

Q: Is the price of Newlline really cheaper than that of Gangnam? What is the reason for this price difference?

A: Indeed, the prices are 20-30% lower than those of similar clinics in Gangnam District. There are mainly three reasons for this: first, the single-director system reduces the operating costs associated with multiple doctors; second, the rent in the Seongsu-dong area is lower than that in Cheongdam-dong, Gangnam; third, the clinic adopts a cost-effective approach, avoiding extravagant decorations and instead investing the budget in equipment and the skills of its doctors. The quality of the equipment and medications has not been compromised in any way.

Q: Can I have the treatment done on-site on the same day, or do I need to make an appointment in advance?

A: It is highly recommended to make reservations in advance. Since the service is provided by a single director, the number of guests that can be accommodated each day is limited, so it is very likely that you will have to wait if you arrive without a reservation. This is especially true on Friday afternoons and Saturdays, when reservations are almost always necessary. Making reservations through the BeautsGO APP is the most convenient option, as its Chinese interface is easy to use.

Q: How can I contact you if there are any issues after the procedure? Are there still after-sales services available after returning to Taiwan?

A: You can contact the Chinese customer service via WeChat (WeChat ID: Hannah972) (Le). Any issues that arise after the procedure can be discussed immediately. Even after returning to Taiwan, the customer service will continue to monitor your recovery progress, a feature that has been specifically mentioned by many users in their reviews on Google.
