Hospital Overview
Secret Clinic (韩文：시레트의원) is an integrated clinic in Gangnam, Seoul, specializing in anti-aging treatments, skin tightening procedures, and contour filler injections. As part of the BeautsGO platform’s network, it is a certified facility whose information is publicly available. For international tourists who prefer to compare prices, read reviews, and schedule appointments through this platform, it helps significantly reduce the risk of information asymmetry.
Location and Atmosphere
The actual address of the clinic is “5th Floor, Namyung Building, 458 Gangnam-daero, Gangnam-gu, Seoul”. Gangnam-daero is the main street leading to Gangnam Station, where numerous Dermatology, plastic surgery, and anti-aging clinics are located. It’s also one of the most well-known routes for international patients seeking medical aesthetics treatments. Situated on the 5th floor of the building, the clinic offers a relatively quiet environment free from the need to queue outside in the busy street—making it an ideal choice for those who value privacy and prefer a low-key experience.
In terms of transportation, the hospital is located near Gangnam Station on Seoul Metro Line 2. For detailed information on exits and walking routes, be sure to check the facility details on BeautsGO to avoid unnecessary detours due to the wrong exit choice. For those visiting Gangnam for medical aesthetics treatments for the first time, scheduling your appointment during off-peak hours in the morning or afternoon will help you have a more relaxed day, giving you plenty of time to undergo light post-treatment care and rest in the area.
Features & Reviews
Secret Hospital isn’t just a clinic focused on single procedures; instead, it integrates “anti-aging tightening” and “contour filling” into a unified treatment approach. According to the hospital’s website, it offers AI 3D analysis for diagnosis, allowing patients to visualize their facial contours, skin texture, and areas of sagging through imaging and data before surgery. This enables tailored plans that combine filling, tightening, and skin management strategies—rather than treating individual areas in isolation.
Based on the services offered publicly, this clinic excels in three main areas. First is Filler treatment using products like Juvederm and Perlane, which help fill in wrinkles and refine facial contours. Second are energy-based tightening methods such as Sylfirm Potenza, ONDA, the second-generation HIFU, and Thermage, designed to address Pores, fine lines, skin laxity, and overall skin quality. Third are regeneration and repair treatments like Rejuran PN Black Box and Red Box, aimed at enhancing skin texture and hydration. This three-pronged approach—filling, tightening, and improving skin quality—is precisely the mainstream strategy adopted by modern anti-aging clinics, and it’s what gives secret its distinct identity among the many clinics in Gangnam.
Introduction to Key Services
Based on the reference prices and service types published by BeautsGO, the following outlines Secret Hospital’s flagship treatment options one by one. All prices listed are public reference figures from the platform; the actual fee will still be determined according to the clinic’s assessment on the day of consultation.
Juvederm 5cc Filling with Juvederm
Juvederm is an internationally renowned brand of Filler that utilizes VYCROSS cross-linking technology, resulting in a texture that is both smooth and highly supportive. The 5centum core filling treatment offered by Secret Hospital is ideal for those who need extensive contour refinement, such as sunken temples, loss of volume in the mid-face, or a lack of definition in the chin or jawline. With 5centum core, there’s enough volume to address multiple areas simultaneously, helping to create a more balanced overall appearance rather than just fixing individual issues.
In principle, Filler can absorb several times its own weight in water, filling in volume gaps and supporting tissues. Thanks to its uniform particles and high elasticity, Juvederm provides a natural feel after injection, with little to no noticeable granular texture. The effects typically last between 12 and 18 months, depending on the injection site, metabolism rate, and lifestyle habits. The starting price is around ₩1,475,000.
Belotero 1cc Filler for Softening Wrinkles
Borou-Tei is another type of Filler with distinct characteristics. Its CPM cohesion matrix technology enables the gel to blend more evenly with skin tissue, making it particularly suitable for refining shallow areas and fine lines such as Tear trough correction, fine wrinkles, areas around the lips, or superficial depressions. Compared to supportive products, Borou-Tei places greater emphasis on “natural integration,” reducing the risk of blue translucency or visible boundaries on the skin surface.
For those trying filler for the first time and looking to start with a low dose, 1 centum core offers a low-threshold, risk-controlled entry point. The duration of effects typically lasts between six months and twelve months, depending on the treatment area and individual metabolism. The reference price starts at ₩308,000, making it the cheapest filler option on the list.
Obsidian Dual-Glass Potenza SWOMAN Sylfirm
Sylfirm is a device that combines the use of Potenza with bipolar radiofrequency technology. Its ultra-fine, gold-plated needles penetrate the epidermis to deliver precise radiofrequency energy deep into the dermal layer, thereby triggering repair processes and enhancing skin firmness. Secret Hospital has named this treatment “Obsidian Dual-Glass Potenza,” emphasizing its capabilities in reshaping the skin texture, reducing Pores, and addressing redness and fine lines. The tiny channels created by the needles promote the production of new Collagen, while the radiofrequency waves heat the dermis to tighten sagging skin.
These treatments are ideal for those with rough skin, prominent Pores, early signs of aging and sagging, or those who need enhanced recovery after procedures. Since the energy can be applied in gradual stages, the clinic offers two options: a single session or a three-session package. The reference price for a single session is ₩198,000, while the three-session package costs ₩528,000—making it more cost-effective per session and better aligned with the natural progression of collagen regeneration. There may be mild redness after the treatment, but normal activities can usually be resumed within one to three days.
ONDA Body Therapy combined with the 2nd-generation HIFU treatment
ONDA is a body sculpting and tightening device that utilizes Coolwaves millimeter-wave technology to target fat layers and connective tissues. It’s ideal for addressing localized sagging, cellulite, and helping refine body contours. Secret Hospital offers the “Body ONDA 120kJ” treatment at a reference price of ₩990,000, designed for those looking to improve specific areas of their body shape.
A more advanced option is the combined treatment of “Ulthrea 2nd Generation 300 shots + Thermage 600 shots + ONDA 80K,” with an estimated price of ₩3,460,000. This package integrates three energy devices that target different depths of the skin: Ulthrea 2nd Generation uses focused ultrasound to address the fascia layer, providing deep-level lifting; Thermage employs monopolar radiofrequency to heat the dermis thoroughly, helping to reduce sagging and improve skin texture; ONDA targets localized fat and contour issues. By working together, these treatments are ideal for those who want to address multiple signs of aging at once. However, the dosage and treatment area should be determined based on individual conditions, as there’s no need to blindly pursue a high number of shots.
Thermage for the Eyes and Rejuran Series
“225 Shots of Thermage for the Eyes” – suggested price: ₩990,000. This treatment is specifically designed to address fine lines, skin laxity, and weak eyelids around the eyes. Due to the thin skin and dense network of nerves and blood vessels in this area, a specialized probe and precise technique are required, which is why it’s offered as a separate eye treatment package. Thermage’s monopolar radiofrequency delivers gentle heating to stimulate collagen contraction, helping to improve mild cases of drooping eyelids.
In terms of regenerative repair treatments, Secret Hospital offers both Rejuran PN and Rejuran HB. The “Rejuran PN Healer 4cc + Eye Rejuran 1cc” comes at a reference price of ₩630,000; it’s used for restoring and hydrating the entire face, while also addressing dryness and fine lines around the eyes. The “Rejuran HB plus 4cc” has a reference price of ₩690,000 and focuses on evening out skin tone, strengthening the skin barrier, and enhancing overall luminosity. These two products are considered maintenance injections, ideal as a foundation treatment for the skin in addition to filler and energy therapy procedures.

Introduction to the Medical Team
Regarding physician information, this article is based on publicly available data and does not fabricate any details such as the names, educational backgrounds, awards, or years of experience of specific doctors or clinic directors. The following content focuses on the nature of the clinic and the professional expertise of its medical team.
Secret Hospital is staffed by board-certified specialists in Dermatology, which is crucial for anti-aging and filler treatments. Filler injections aren’t just about simply filling in hollows—they require an understanding of anatomical layers, blood vessel distribution, and aesthetic proportions. The specialized training of these dermatologists helps them assess skin conditions before treatment, select the right products and dosages, and reduce the risk of complications.
The clinic emphasizes a “comprehensive approach that combines anti-aging tightening with contour filling,” meaning it doesn’t rely on a single treatment as the ultimate solution. Instead, it tailors a combination of filler treatments, energy-based tightening procedures, and skin management strategies based on each individual’s specific signs of aging. What’s more, platform data shows that the clinic places great importance on pre-operative AI 3D analysis and diagnosis, as well as post-operative follow-up: baseline measurements are taken using imaging and data before treatment, and adjustments are made according to recovery progress afterward, ensuring the treatment plan is well-founded and easier to monitor and communicate about.

Frequently Asked Questions
Q1: Are Filler treatments and energy-based therapies painful? Filler injec
tions usually come with topical anesthesia or ice application, and patients mainly experience swelling, discomfort, and a sense of pressure during the procedure. Energy therapies such as Sylfirm and Thermage cause a warm sensation along with brief stinging pains, which most people can tolerate. Individual experiences vary, so you can discuss pain-relief methods with your doctor before the treatment.
Q2: How long does the effect last? Juvederm typically
provides effects that last around 12 to 18 months, while Perlane lasts about 6 to 12 months. Sylfirm’s collagen-renewing effect builds up with each treatment session, and it’s recommended to start with a three-session package to establish a solid foundation. Thermage and the second-generation HIFU both offer firming results that generally last around a year. An individual’s metabolism, age, and lifestyle all play a role in determining how long the effects persist.
Q3: How long is the recovery period after the procedure? M
ost filler and energy-based treatments require little downtime. Injection procedures may cause mild bruising or swelling that usually subsides within a few days; Sylfirm can result in redness that lasts about one to three days. It’s recommended to strengthen sun protection and moisturization after the procedure, and to avoid hot environments (saunas, intense exercise) for one to two days.
Q4: How should I determine a reasonable price? The prices listed
on the platform are merely reference values; the final quote will be adjusted based on the dosage, treatment area, and individual plans. Instead of focusing solely on the unit price, it’s more important to consider whether the “overall treatment approach” meets your needs—such as whether a combination treatment for filling and tightening is comprehensive enough, and whether it includes pre-operative assessment and post-operative follow-up.
Q5: How can foreigners make appointments most conv
eniently? The easiest way is to use the BeautsGO app or WeChat mini-program, search for Secret Hospital, select a date and time slot, and rely on Chinese-speaking customer service for assistance. Once the appointment is confirmed, just show up as scheduled—no need to call the clinic directly.
Q6: Is the procedure performed by a specialized doctor?
Given the clinic’s professional setup, Secret Hospital is staffed by Dermatology experts who focus on anti-aging, skin tightening, and contour augmentation treatments. To find out exactly which doctor will be performing the procedure, it’s recommended to check with the platform or the clinic during your appointment or consultation.
Q7: What are the differences between Filler and other types of fillers? Fillers like Fil
ler (such as Juvederm and Restylane) are materials that can be metabolized by the body, and their levels can be adjusted using dissolving enzymes when needed, offering higher safety and reversibility. Other options such as autologous fat or collagen-stimulating treatments each have their own specific indications. When making a choice, it’s important to consider factors like the treatment area, desired results, and duration of effect—not just price.
