A Medical Guide to Rejuran: The Secret to Skin Regeneration in Seoul
As a Licensed Doctor of Korean Medicine and a Medical Interpreter based in Seoul, I spend a lot of time in dermatology clinics. In my role, I have had the opportunity to observe many international patients in Seoul's dermatology clinics, witnessing how they choose and react to different treatments like Rejuran.
Seeing firsthand how patients prioritize skin health and watching their skin texture naturally improve over time is what inspired me to write this guide. I want to provide a clear, professional breakdown of why Rejuran has become a cornerstone of the K-Beauty wellness journey for so many people.
1. The Science: What is Polynucleotide (PN)?
Rejuran is not a typical filler that adds artificial volume. Instead, it is a "biostimulator" composed of Polynucleotide (PN), which is a DNA fragment extracted from salmon.
- DNA Compatibility: Salmon DNA is remarkably similar to human DNA, ensuring high safety and minimal immune response.
- Cellular Regeneration: PN acts as a scaffold that triggers the skin's natural healing response, stimulating fibroblasts to produce fresh collagen and elastin.
- Dermal Thickening: By repairing the skin from within, it increases the thickness and density of the dermis, which naturally thins as we age.
2. Rejuran Family: Choosing the Right Type for Your Needs
Through my observations in the field, I’ve noticed that the best results come from choosing the specific type of Rejuran that matches the target area.
| Type | Target Area | Texture | Key Benefits |
|---|---|---|---|
| Rejuran Healer | Full Face | Medium | Overall elasticity, barrier repair, and oil-water balance. |
| Rejuran I (Eye) | Periorbital Area | Low (Thin) | Treats dark circles and fine lines without causing lumps. |
| Rejuran S (Scar) | Scars / Acne Marks | High (Thick) | Specialized for depressed scars; promotes deep regeneration. |
| Rejuran HB Plus | Dry Skin | Medium | Combined with Hyaluronic Acid & Lidocaine for less pain. |
3. The Realities: Pros, Cons, and the "Pain Factor"
The Pros & Cons
Based on the feedback I have translated from patients, Rejuran offers long-lasting structural health and a high safety profile. However, it requires patience. The temporary "embossing" (small bumps) typically lasts 24 to 48 hours, and most patients require 3 sessions to see dramatic changes.
Pain Management: Is Sleep Anesthesia Necessary?
This is the most frequent question I encounter. While numbing cream is sufficient for many, Sleep Anesthesia (IV Sedation) is an increasingly popular option in Seoul for those who want a completely stress-free experience, especially when combining multiple treatments.
4. A Doctor's Perspective: Maximizing Your Results
From the lens of Korean Medicine, the effectiveness of any treatment depends on the body's internal environment. To ensure the PN works efficiently:
- Hydration: PN works best in a well-hydrated environment. Drink plenty of water post-treatment.
- Avoid Heat: Steer clear of saunas and intense workouts for at least one week to prevent unnecessary inflammation.
- Patience: In my observation, the most visible results appear about 2 weeks after the second session.
Conclusion: A Synergy of Science and Soul
My dual role has taught me that the best beauty treatments are those that respect the body's natural biology. Rejuran Healer is a perfect example of this philosophy. By providing the skin with the tools it needs to repair itself, we achieve a radiance that is truly "inside out."
