Taiwanese tourists who fly to Gangnam in Seoul for cosmetic treatments have quietly switched to AYUN Dermatology in recent years. The key advantage here isn’t just the lower prices, but rather the fact that it’s overseen personally by a director who holds expert certifications from both Rejuran and Juvelook manufacturers, turning “personalized treatment plans” into a structured, actionable process. This article explores the real reasons why Taiwanese choose AYUN, what these dual certifications mean, how Rejuran and Juvelook compare, and everything you need to know before making the trip.
Why do so many Taiwanese fly to Gangnam AYUN Dermatology?
Who are the dual Expert-certified directors at Gangnam AYUN Dermatology?
👩⚕️
【Dual Certification Is Not Just Marketing Fluff】: The director of AYUN holds official Expert certifications from both Rejuran and Juvelook, proving that they have received training in the proper injection techniques and safety protocols provided by the manufacturers.
【In-person Consultation System Replaces Assistant Procedures】: From the initial consultation and design to the actual treatment, everything is handled personally by the clinic director, minimizing communication gaps and inconsistencies in procedures—something that’s especially important for international patients.
【High proportion of Taiwanese clients】：Located in the bustling commercial district around Gangnam Station, the clinic offers low transportation costs for Taiwanese tourists who are used to traveling to Seoul for cosmetic procedures on their own. Its excellent reputation continues to spread across social media and forums.
What does dual certification of Rejuran + Juvelook at Gangnam AYUN Dermatology mean?
💡
【Certified by Original Manufacturer for Quality Assurance】: The dual Expert certification ensures that the needles used in the clinic meet the original manufacturer’s standards in terms of source, dilution ratio, and injection depth—rather than being based on the clinic’s own arbitrary treatment names.
【Two complementary ingredients】：Rejuran uses PN polynucleotides to repair the skin’s underlying layers, while Juvelook employs PCL to stimulate collagen production. With dual certification, dermatologists can handle both “repair” and “support” functions within the same treatment session.
【Reduce the risk of making bad choices】: For international travelers, original manufacturer certification is the easiest way to verify credibility, offering more reliable guidance than just looking at influencer photos.
What’s the difference between Gangnam AYUN Dermatology’s customized approach and its mass-production model?
🪄
【Assessment before treatment】: Upon arrival, the clinic director will examine your skin condition, assess its contours, and ask about your goals before deciding where and how much to inject—rather than imposing a fixed package as soon as you enter.
【Dose adjusted per individual】: Even for Rejuran, the application areas and concentrations vary for those with dry skin and sensitive skin. The key to customization lies in these subtle differences.
【Trackable Injection Records】: Every injection site and dosage are recorded, allowing seamless continuity during follow-up visits or your next trip to Korea, thus preventing repeated injections or omissions.
How are Rejuran and Juvelook injected at Gangnam AYUN Dermatology?
What skin types are suitable for Rejuran at Gangnam AYUN Dermatology?
🫧
【Repair-Oriented】: Rejuran features its PN ingredient to restore damaged skin layers, making it ideal as a foundational treatment for those with dull skin from staying up late, post-surgery recovery needs, or rough skin texture.
【It’s not just moisturization】: It functions more like underlying repair that helps the skin improve on its own. Results usually emerge gradually within a week after treatment, rather than showing immediate effects.
【Can be combined with other treatments】: The clinic director often uses it as a recovery base after laser or ultrasound treatments to ensure a smoother recovery process and faster reduction of redness.
Why is Juvelook from Gangnam AYUN Dermatology the right choice for young adults?
✨
【Collagen-Stimulating Type】: Juvelook uses PCL microspheres to stimulate the body’s natural collagen production, providing firming effects against Pores, fine lines, and mild sagging—rather than simply adding volume.
【Gentle Progression】: Its collagen stimulation occurs gradually over a period of 1–3 months, making it ideal for younger adults who prefer not to see dramatic changes at once.
【Longer-lasting effect】: Compared to regular moisturizing injections, Juvelook provides sustained coverage that can last for several months, reducing the need for frequent follow-up visits and keeping travel costs more manageable.
Can Rejuran and Juvelook be used together at Gangnam AYUN Dermatology?
💡
【Can be applied in layers】：Under the expertise of a dual-certified dermatologist, Rejuran works to restore the skin’s foundation while Juvelook provides collagen support—both can be applied at different layers during the same treatment session.
【Order matters】: Typically, deep-layer support is addressed first, followed by the repair layer. The specific sequence is determined by the clinic director based on the condition of the face; it’s not recommended to decide the layers on your own.
【Separate post-surgery care is required】: The swelling and redness reduction rates for the two types of injections differ. In the days after treatment, it’s important to strengthen sun protection and hydration, while avoiding high-temperature environments.

Comprehensive Guide to Post-Procedure Care and Common Questions at Gangnam AYUN Dermatology
⚠️
【The first three days are crucial】: Avoid massaging the treatment area, exposure to high temperatures or saunas, and strenuous exercise within 3 days after the procedure to help the injections stabilize at their targeted depth.
【Sun protection is more important than skincare】: Strengthening sun protection and gentle moisturization in the first two weeks can significantly impact the final results of collagen production and skin repair—don’t focus only on applying skincare products.
【Manage the timeline of results】：Rejuran shows effects gradually over about a week, while Juvelook takes 1–3 months. Don’t judge whether it’s successful based on whether there are changes on the same day.
