I visited three Dermatology clinics in Gangnam for anonymous consultations, without telling any of them what specific treatment I was interested in—just saying I wanted to improve my skin condition. At the first clinic, the consultant talked with me for 20 minutes, while the doctor came in for just 3 minutes before leaving. The second clinic went even further, immediately pushing package deals at me for selection. It wasn’t until the third clinic—the RERA Dermatology clinic run by Director 오두진—that I had a one-on-one experience from initial consultation and skin testing to plan formulation; he didn’t leave once, and he even asked about my sleep patterns and skincare habits. Right there, I knew this place was different.
In this article, we’ll take a thorough look at this hidden gem of a Dermatology clinic located just 5 minutes’ walk from Cheongdam Rodeo Station—ranging from introductory consultations starting at ₩10,000 to premium Thermage FLX packages priced at ₩2,100,000, offering private treatment in one-on-one sessions. We’ll also explore why patients with stubborn pigmentation issues highly recommend this clinic on Naver.
Where Exactly Is RERA Dermatology in South Korea? A Complete Guide to Getting There
RERA Dermatology (리라피부과의원) is located on the 7th floor of the Geumgang Building at 806 Seonnyeong-ro, Gangnam-gu, Seoul. The nearest subway station is Apgujeong Rodemo Station on the Bundang Line. Exit No. 4 and walk along Seonnyeong-ro for about 300 meters – you’ll arrive in just 5 minutes. You’ll pass by Cheongdam-dong’s famous shopping street along the way, and it’s very easy to find using navigation.
If you’re driving, there are parking spaces available from B2 to B4 underground at the Geumgang Building. Patients who attend a 1-hour in-person consultation can receive a 2-hour free parking voucher, which is very convenient for those who drive. Right nearby are Cheongdam-dong’s famous brand street and Rodeo Fashion Street, so you can go shopping and dining after your treatment, making it easy to plan an entire day’s itinerary. Also located in the Cheongdam-dong area, Cheongdam OKAY Dermatology is well-known for its Thermage treatments. The two clinics are not far apart, so you can consider getting consultations at both if you’re comparing prices.
South Korea’s RERA Dermatology Price List 2026: Starting from ₩10,000 for Basic Treatments to ₩2.1 million for Premium Services
RERA Dermatology offers a highly transparent pricing structure, with its official website openly displaying the 수가표 (treatment fee schedule). This level of honesty is quite rare among dermatology clinics in South Korea. I’ve compiled the latest quotes from their official site:
| Treatment Options | Pricing Method | Reference price |
|---|---|---|
| General outpatient consultation | Every time | ₩10,000 |
| Inflammatory injection | Each (including tax) | ₩11,000~22,000 |
| Removal of moles/fat spots (under 1mm) | Each one | ₩10,000 |
| verruca plana | Each (under 1mm) | ₩10,000 |
| Acne Treatment | Every time | ₩30,000~500,000 |
| Tattoo removal | Every time | ₩100,000~300,000 |
| Whitening Treatment | Every time | ₩150,000 |
| Lifting Treatment (including HIFU/Thermage) | Every time | ₩100,000~2,000,000 |
| Botulinum bacteria | By Body Part | ₩60,000~350,000 |
| Fillers (such as Filler) | By Body Part | ₩150,000~400,000 |
| Skin Management | Every time | ₩80,000~200,000 |
Another package option found on the BeautsGO platform is: Thermage FLX 600 treatment plus 3cc of LORIENT ELEMENT hyaluronic acid injection = ₩2,100,000. This combo combines lifting effects with hydration in one session, making it RERA’s flagship treatment package.
Compared to Thermage FLX offered by PASCAL Dermatology, RERA adopts a pricing strategy that emphasizes “no bundled packages, choose based on your needs.” You can opt for just a ₩10,000 consultation, or upgrade to a premium package costing up to ₩2.1 million. The decision is entirely based on the results of your skin assessment, with no pressure to buy anything extra. (All prices listed do not include 10% VAT.)
5 Key Advantages of RERA Dermatology: Features Most Frequently Mentioned on PTT and Dcard
- “The director is with you one-on-one from start to finish—nothing like having a consultant talk to you for half an hour first.” That was my immediate impression after testing three clinics anonymously. Director Oh Du-jin stays by your side throughout the entire process, from the initial consultation and skin assessment to formulating a treatment plan, even asking about your daily habits. For those seeking this kind of anti-aging experience where the director personally oversees everything, RERA is one of the rare options in Gangnam these days.
- “Having your own private room means no interruptions at all—completely different from the Dermatology departments in department stores.” RERA features a one-person waiting room, a one-person consultation room, and a one-person laser treatment room, so you won’t encounter other clients from the moment you enter until you leave. This design is a huge plus for those who value privacy.
- “Expertise in treating refractory pigmentation – even nevus can be addressed”: One of RERA’s flagship services is 난치성 색소치료 (treatment of refractory pigmentation), with real patient cases available even for pigmented conditions like nevi. Many reviews on NAVER mention that “while other clinics say it’s impossible, RERA is willing to give it a try.”
- “Sleep anesthesia is provided by on-site anesthesiologists”: It’s not outsourced anesthesiologists — experienced specialist anesthesiologists take full responsibility. This is a huge relief when undergoing procedures that are sensitive to pain.
- “Not only treatment, but also guidance on at-home care”: Director Oh Du-jin’s philosophy in treating patients is that “skin problems are sometimes caused by lifestyle habits.” Therefore, during consultations, he not only prescribes treatment plans but also offers advice on at-home care tailored to your lifestyle, helping to maintain results for longer.
Dr. Odujin’s philosophy of treatment: Why “finding the cause” matters more than “doing everything”
Dr. Oh Doo-jin is a board-certified specialist in Dermatology and the lead physician at RERA Dermatology. What impressed me the most during our consultation was something he said:
“Skin issues are sometimes caused by lifestyle habits. It’s not enough to just treat the symptoms—you need to identify the root cause.”
This isn’t just a slogan. During the in-person consultation, Dr. Oh Du-jin will ask about your sleep patterns, stress levels, daily skincare routine, and even eating habits, so as to determine the root causes of your skin issues. He believes that many skin problems—such as recurring acne and pigmentation—are related to lack of sleep, high stress, and poor skincare habits, and that treatment alone cannot address these underlying issues.
So, the process at RERA is as follows: skin testing → analysis of lifestyle habits → identification of the root causes → formulation of a treatment plan → guidance on home care. This approach is completely different from those other clinics that simply recommend treatment packages right after the testing. If you value this kind of Gangnam Dermatology consultation experience that focuses on solving problems at their source, RERA is definitely worth adding to your list.
Actual Time Line for Thermage FLX Treatment: Right after treatment → 7 days → 1 month
Thermage FLX is one of the five flagship treatments offered by RERA. I’ve compiled the most frequently mentioned post-treatment experience timelines found on PTT and Dcard:
| Timing | The most common reactions from netizens | My observations |
|---|---|---|
| Right after it was done | “My face feels a bit tight, like it’s after using a mask that’s dried up.” | The treatment area felt slightly warm, but there was no redness or swelling. Director Oh Du-jin checked on me right away to ensure the injection was even. |
| 7 days later | “The chin line is starting to appear, and it’s most noticeable in side-profile photos.” | The tension fades away, and the skin texture returns to normal. The facial contours start to tighten up, and my friends say my face looks smaller. |
| 1 month later | “This is when the effect is most noticeable—the Nasolabial Fold Correction becomes much less visible.” | Collagen reconstruction reaches its peak phase, with the most noticeable improvement in sagging. This is the golden period for seeing results. |
First-hand experience with treating refractory pigmentation: Why melasma can also improve
Another highlight of RERA is its treatment for refractory pigmentation disorders. The official website features a real patient case — Model Huang O-sik, who suffered from nevus syndrome along with acne issues. After receiving combined treatment for pigmentation and acne at RERA, her condition improved significantly.
The reason why refractory pigmentation is so difficult to treat is that deep-seated pigments require multiple treatment sessions and tend to recur easily. RERA employs precise treatment protocols combined with top-tier lasers to address pigmentation at different depths in stages. Dr. Oh Du-jin will customize a treatment plan based on your specific type of pigmentation—whether it’s superficial spots, deep-seated spots, or hormonal spots—rather than using a one-size-fits-all approach. For more insights into the combined use of HIFU and treatments for pigmentation, you can also check out this in-depth review.
You can’t tell exactly what was done, but it just looks better: RERA’s Natural Aesthetics
RERA follows a “natural” aesthetic approach — after the procedure, you won’t turn into a completely different person, but your friends will notice things like “You look so radiant” or “Have you lost weight?” The core of this aesthetic philosophy is to avoid excessive corrections and focus only on addressing the issues that truly need improvement.
For example, if you undergo Thermage FLX treatment, Dr. 오두진 won’t recommend using large amounts of fillers at the same time to “enhance the results.” Instead, he suggests using Thermage to help the Collagen regenerate naturally, and then assessing after one month whether further supplementation is needed. This “less is more” approach makes the outcome appear more like “improved skin health” rather than “the result of cosmetic surgery.”
Comparison Table of Rivals in Gangnam: RERA vs Cheongdam OK vs PASCAL
| Comparison Items | RERA Dermatology | Cheongdam OKAY Dermatology / PASCAL Dermatology |
|---|---|---|
| Target Audience | Those who value privacy and seek natural-looking results | Those seeking quick results through a combination of multiple treatments |
| In-person consultation style | The director provides one-on-one guidance throughout the process, delving into lifestyle habits. | The consultant conducts an initial consultation, followed by confirmation by the doctor. |
| Operator | Dr. Odujin personally performs the procedure one-on-one throughout the whole process. | Varies depending on the treatment plan and branch location |
| Privacy by Design | One room per person (separate areas for waiting, management, and laser treatment) | Primarily designed for multiple people to share the space |
| Review Keywords | Expertise in natural, non-surgical treatment of persistent pigmentation issues | Convenient, fast, with a wide range of options |
In short: if you’re looking for efficiency and more options, PASCAL and Cheongdam OKAY are better choices; but if privacy is a top priority, you want the director to oversee everything personally, and your skin issues are quite complex (especially pigment-related ones), then RERA’s one-person-per-room service offers significant advantages.

What’s the atmosphere like at RERA Dermatology?
Upon entering the 7th floor of RERA Dermatology, the first impression is one of tranquility. Thanks to its fully reservation-based system along with a one-patient-per-room design, there are no other clients waiting in the lobby. The waiting area is a separate little space equipped with comfortable seating and soft lighting.
The treatment areas are divided into a single-client consultation room and a single-client laser treatment room, with each space being completely independent. They’re equipped with ventilation systems on par with those used in operating rooms, along with rigorous disinfection protocols. Dr. Oh Dujin specifically mentioned during the consultation that their disinfection procedures are stricter than those in regular Dermatology clinics, as treatments for refractory pigmentation issues often require multiple sessions, increasing the risk of infection when the skin barrier is already weakened.
The overall atmosphere here is characterized by being “clean, quiet, and uncluttered.” There’s no overly luxurious decoration, but every detail is thought out to ensure privacy and hygiene. This aligns perfectly with RERA’s mission — it’s not just another place for photo ops, but a genuine facility dedicated to providing medical treatments.

5 Common Mistakes to Avoid at RERA Dermatology (Learned from Real People’s Painful Experiences)
- Never choose a treatment plan without first getting a skin assessment: The real advantage of RERA lies in Director 오두진’s precise diagnosis. Skipping the assessment means wasting his expertise. Many people simply say, “I want to do Thermage” after seeing online recommendations, only to find out later that it’s not necessary at all after the doctor’s evaluation.
- Avoid scheduling appointments during lunch break: 13:00–14:00 is reserved for lunch breaks, and the clinic does not accept new patients. Many people fail to notice this and end up showing up only to be turned away.
- Avoid using acidic skincare products 3 days before the procedure—it increases the risk of sensitivity after treatment. Dr. Oh Du-jin will remind patients during the in-person consultation, but many people forget.
- Avoid exposing yourself to the sun right after treatment: Especially after pigment therapy, failing to use adequate sun protection can lead to discoloration. Some users on Dcard shared that going to Myeongdong the day after treatment caused the pigmentation to reappear even faster.
- Don’t wait until 3 days before your trip to make a reservation: RERA operates on a reservation-based system with one room per person, and availability is limited. For popular times, you should book at least 1–2 weeks in advance, especially on weekends. Many people only schedule their reservations after their itineraries are finalized, only to find that rooms are unavailable and force them to choose another place.
What should you prepare for your first visit to RERA Dermatology? Pre- and post-surgery tips
Preoperative Preparation
- Prepare natural-light photos: front view, side views, and 45-degree angles—avoid using beauty filters so the doctor can see the true condition of your skin.
- Medical history inquiry: Whether taking aspirin currently, presence of angioedema tendency, and any drug allergies.
- Be specific about your goals: Clearly state “I want to improve my Nasolabial Fold Correction” or “I want to get rid of the spots on my cheeks,” rather than just saying “I want to look better.”
- Avoid using acidic skincare products and exfoliating agents 3 days before the procedure, and pause retinol and fruit acids as well.
- Get enough sleep the day before the procedure and avoid drinking alcohol.
Post-surgery precautions
- After Thermage FLX: Avoid hot baths for one week, refrain from applying heavy pressure to the face, and stay away from saunas.
- After pigment treatment: Avoid picking at the scabbed areas within 3–5 days, keep them lightly moisturized, and use sunscreen with an SPF of at least 50+.
- After Botox treatment: Avoid lying flat for 4 hours, do not massage the injection area, and refrain from strenuous exercise for 24 hours.
- After all treatments: avoid alcohol and saunas for one week, and apply sunscreen daily (even indoors).
- Following the at-home care steps taught by Director Oh Du-jin is indeed key to prolonging the results.
The Real Verdict: Is RERA Dermatology Worth Visiting?
Returning to the initial question—after trying three Dermatology clinics in Gangnam through blind tests, RERA was the only one that made me want to book an appointment right away. The reason is simple: Director Oh Dujin’s one-on-one consultation approach, combined with private treatment rooms for each patient, turns cosmetic procedures from a routine process into a truly personalized experience tailored to your skin condition.
If this is your first time undergoing cosmetic treatments, you have complex skin issues (especially pigment-related problems), or you simply hate being pressured into buying package deals—RERA is definitely worth adding to your list. The introductory consultation fee of ₩10,000 isn’t expensive at all. It’s best to let Director 오두진 conduct a skin assessment first, before deciding whether to proceed with further treatments. This is the most logical approach.
One final reminder: RERA operates on a reservation basis, so it’s advisable to book 1–2 weeks in advance during peak times. Make sure to confirm the schedule via LINE before you head out, so as to avoid delays at the booking stage.
