I’ve been to several Dermatology clinics in Gangnam. What impressed me the most wasn’t the treatment results, but rather the waiting system. You had to draw lots, wait in groups, and spend five minutes talking with a consultant before the doctor even showed up for less than three minutes. After the procedure, I couldn’t even tell who actually performed the injection on me.
Later, I saw someone on a forum mention Cheongdam Rera Dermatology, saying that they “even provide you with a private room while waiting for your appointment.” How is Cheongdam Rera Dermatology? At first, I thought it was just marketing fluff, but after checking out their public information, I realized that the difference between Cheongdam Rera Dermatology and the Gangnam chain lies not in the equipment, but in the treatment process.
In short: Cheongdam Rera Dermatology operates on a fully reservation-based system. Led by Director Wu Douzhen, patients receive personalized care with the same doctor handling everything from consultation to treatment, with each step taking place in a separate space. The downside is that it’s closed on Sundays and only open until 5 PM on Saturdays, offering less flexibility compared to larger chains. If you want to compare prices and book slots first, use BeautsGO; if you’re still deciding what treatment to have, reach out via the LINE Chinese account.
Is it worth making a special trip to Rera Dermatology in Cheongdam? Let’s start with the conclusion.
It’s worth it, but only suitable for specific itineraries. The main advantages of Cheongdam Rera Dermatology lie in the fact that Director Oh Doo-jin treats each patient in a private room without any handoffs, along with a fully reservation-based system—perfect for those who prioritize privacy and high-quality communication. If your top priority is being able to visit last minute or have appointments on Sundays, Cheongdam Rera Dermatology might disappoint you.
✅ Worth adding to your itinerary
• Hate waiting in groups and don’t want to sit next to strangers while getting anesthetic injected
• Prefer having the same doctor handle both the initial consultation and post-surgery follow-up
• The main concerns are sagging and fine lines; Ulthrea or Thermage FLX are the top choices.
• The schedule is set from Monday to Friday, allowing for appointments starting at 10:00.
❌ It’s recommended to try another clinic.
• Departures are only possible on Sundays (Cheongdam Rera Dermatology is closed on Sundays).
• Want to walk in and register on the same day (all appointments required; no walk-in slots available)
• The only consideration is keeping the per-session price as low as possible
• There are many people scheduling appointments; I want to book my treatment at the same time as them.
What’s the difference between Cheongdam Rera Dermatology and the Gangnam chain? “One room per patient” isn’t just about decor—it’s part of the service process.
Many people assume that “one room per patient” means better decor, but the real difference lies in the workflow. At the large-chain clinics in Gangnam, the process is “drawing lots, waiting in groups, consultation by a specialist, and treatment by a doctor.” At Rera Dermatology in Cheongdam, it’s “checking in after making an appointment, waiting in a dedicated room, being examined by Director Wu Douzhen, and receiving treatment in the same space”—with no changes in staff or rooms throughout the process.
| Steps | Common procedures at large Gangnam chain stores | The Process at Cheongdam Rera Dermatology |
|---|---|---|
| Waiting Room | Group waiting area, number call system | Private waiting room for 1 person |
| Consultation | Led by consultants; doctors may not be present. | One-on-one consultation with Dr. Wu Douzhen |
| Injection | It might be handed over to another doctor for the procedure. | Dr. Wu Douzhen took full responsibility throughout the entire process. |
| Post-Procedure Instructions | Instructions are given uniformly by the nursing staff | President Wu Douzhen explained in person |
| Anesthesia | Usually a topical anesthetic ointment | Sleep anesthesia can be arranged, with a specialist anesthesiologist providing full supervision throughout the procedure |
Just how saturated is the supply side? According to statistics from the Ministry of Health and Welfare and the National Health Insurance Service, as cited on the official Chinese website of the South Korea Tourism Organization, there were 571 Dermatology clinics in Seoul in 2024, with 170 of them located in Gangnam District alone. Despite such a high density of providers, only a few are willing to switch to a fully appointment-based system.
If you want to compare the pricing strategies of anti-aging clinics in Gangnam, it’s recommended to read this first: When seeking anti-aging treatments in Gangnam, don’t just focus on Thermage! ADO Dermatology in South Korea sets separate prices for facial and body treatments—find out whether seeing Director Park Seung-won in person is worth it.
Is Dr. Woo Doo-jin, the director of Rera Dermatology in Cheongdam, a board-certified dermatologist? How credible is this credential?
Yes. Dr. Oh Du-jin holds a certification as a specialist in Dermatology issued by South Korea’s Ministry of Health and Welfare. This is the key differentiator of Rera Dermatology in Cheongdam, and it’s what gives them the confidence to pursue a premium approach in patient care.
Why is this card so valuable? Just look at the two sets of numbers to understand.
- In South Korea, around 90% of clinics that claim to offer skin treatment are run by non-specialist doctors. According to statistics released by the Korean Society of Dermatology on March 30, 2026, as many as 15,000 clinics across the country advertise skin treatment services, yet only 1,516 of them are operated by 2,950 dermatology specialists (Source: Chosun English, March 31, 2026).
- In South Korea, it takes 4 years to become a specialist in Dermatology. After obtaining their medical license, doctors must complete another 4 years of specialized training in the Dermatology department of a university hospital, as well as pass the specialist qualification exam (Source: Official Chinese website of South Korea Tourism Organization).
In other words, in South Korea, “having Dermatology written on the sign” and “the practitioner being a dermatology specialist” are two different things. The Korean Dermatology Association also warns that clinics run by non-specialists often use names like “○○ Clinic – Specializing in Dermatology,” allowing consumers to make an initial judgment just by looking at the sign outside.
Another clinic in the Apgujeong area that emphasizes “consultations by chief dermatologists” is South Korea’s DM Dermatology. Here’s a comparison of the two: First-hand experience with Apgujeong Dermatology | DM Dermatology in South Korea achieves a “natural” look that seems untouched: consultations by chief dermatologists + KAHF certification for foreigners.
The three flagship treatments at Cheongdam Rera Dermatology: Ulthrea, Thermage FLX, and Rejuran injection therapy
If it’s your first time and you can only choose one treatment, start by determining whether your main concern is sagging, loose skin, or dryness. The following three treatments are ranked in order of priority based on their appropriate use cases.
Ultherapy received FDA De Novo approval in the United States in 2009 (K072505) for brow lifting. In 2012, its uses were expanded to chin and neck lifting under approval number K134032. Further enhancements were made in 2014 to address fine lines on the chest. It remains the only device to have earned FDA approval for “non-invasive lifting” (Sources: FDA K072505, K134032).
✅ Suitable for: those with sagging chin lines, drooping neck skin, or those who prefer lifting rather than filling.
Thermage FLX is developed by Solta Medical. It received FDA 510(k) approval in 2017 (approval number K170758), and the South Korea Ministry of Food and Drug Safety (MFDS) granted an import permit in 2018 (permit number 18-245). The official probe specifications include a full-face Total Tip with a surface area of 4.0cm², available in three settings: 900 pulses, 600 pulses, and 300 pulses; and an eye Eye Tip with a surface area of 0.25cm², available in 450 pulses and 225 pulses (sources: FDA K170758, MFDS import permit 18-245, Thermage’s official product page).
✅ Ideal for: those with many fine lines, thin skin, or who want to wear makeup right after the treatment and head out.
The key ingredient in Rejuran Healer is polynucleotide (PN). According to the official Chinese website of the South Korea Tourism Organization, it is listed as one of the three most popular skin boosters in South Korea, known for its ability to enhance skin elasticity, regulate oil balance, and improve skin texture (Source: Official Chinese website of the South Korea Tourism Organization).
✅ Suitable for: first-time visitors to Korea, those with a limited budget, and those who want to test the waters first.

Preoperative Preparation
- Prepare natural light photos: 4 images in total—front view, left side, right side, and 45-degree angle—without using any beauty filters.
- Medical history inquiry: Whether taking aspirin or anticoagulant medications, and whether prone to telangiectasia.
- Be specific about your goals: Clearly state “I want to improve my chin line” instead of just saying “I want to look better.”
- Stop using acid-based skincare products such as AHA and fruit acids, as well as exfoliating products, 3 days before the procedure.
Post-surgery precautions
- After using the Ulthrea: Avoid taking hot baths for a week, and refrain from applying heavy pressure to the face and neck.
- After Thermage FLX: You can apply makeup on the same day, but avoid saunas, ovens, and alcohol for one week.
- After Rejuran dermal filler treatment: Expect mild moisturization for three days, avoid excessive sun exposure, and the needle marks will fade in about 1 to 2 days.
- After all treatments: Apply broad-spectrum sunscreen thoroughly within a week, and wear a hat or umbrella when going outside.
Real Review of Dermatology Rera in Cheongdam: When to Go and When Not to Go
If what you’re looking for is someone to take complete care of your face from start to finish, Dermatology Rera in Cheongdam is definitely worth adding to your schedule. But if you just need to book a treatment last minute on a Sunday afternoon, it’s better to choose another clinic.
- Reasons to visit: Director Wu Douzhen is a Dermatology specialist certified by South Korea’s Ministry of Health and Welfare. With one patient per room and dedicated care throughout the consultation, he offers a level of privacy and personalized service that far exceeds that of the Gangnam chain clinics where patients wait in groups.
- The price to pay first: fully appointment-based service, closed on Sundays, open only until 17:00 on Saturdays, with less flexibility compared to large chains; its premium positioning also isn’t suitable for those who prioritize the lowest price above everything else.
- Steps before you go: First, visit BeautsGO to check the schedule and pricing for Rera Dermatology in Cheongdam. If you haven’t decided on the treatment yet, join the LINE group @901taiqf to discuss in Chinese.
