Maybe you’ve noticed your skin isn’t quite as firm as it used to be, or those fine lines are starting to bother you. 😊 I know I’ve felt that way! We all want that healthy, radiant glow, right? That’s where treatments like Rejuran Skin Booster come in, a popular option often talked about in Korea for its natural skin regeneration benefits.
Understanding Rejuran Skin Booster: What is it and How Does it Work? 🤔
At its core, Rejuran Skin Booster is a treatment that injects Polynucleotides (PN) directly into the dermis layer of your skin. Think of PN as a biocompatible material that kicks your skin’s natural healing and regeneration abilities into high gear.
This special PN substance is purified DNA extracted from salmon reproductive cells. Now, I know that sounds a bit unusual, but because it’s very similar to human DNA, it’s considered quite safe and highly compatible with our bodies. Once injected, the PN promotes skin cell growth and collagen synthesis.
So, how does it actually work its magic? The key PN component stimulates fibroblasts – these are like the skin’s little builders – to produce more collagen and elastin. This process rebuilds the extracellular matrix (ECM), which is basically the structural support system of your skin. By doing this, Rejuran helps to repair damaged skin tissue, leading to increased skin thickness and improved elasticity.
Beyond structural support, PN also has anti-inflammatory effects and boosts the skin’s ability to hold onto moisture, improving the overall oil-moisture balance. This is different from hyaluronic acid (HA) fillers, which primarily just add hydration or volume. Rejuran, honestly, works on restoring the fundamental health of your skin from within.
The PN in Rejuran is derived from salmon DNA, but it’s highly purified and processed to be biocompatible and safe for human injection. It’s designed to work with your body’s natural processes!

The Amazing Effects of Rejuran: What Can You Expect? ✨
Okay, so we know *how* it works, but what kind of results can you actually see? I think the beauty of Rejuran is that it offers a range of benefits, targeting overall skin health rather than just one issue. Here are some key improvements you might notice:
- Skin Elasticity & Fine Lines Improvement: By boosting collagen production, your skin’s density and elasticity improve. This really helps with those pesky fine lines around the eyes and mouth!
- Skin Texture & Pore Improvement: It helps normalize your skin’s regeneration cycle and restores the health of both the epidermis and dermis. This means smoother skin texture and a reduction in the appearance of enlarged pores.
- Oil-Moisture Balance Control: It can help decrease excessive sebum production while increasing the skin’s hydration levels. The result? Skin that looks hydrated and dewy, not overly shiny.
- Skin Tone & Clarity Improvement: By promoting skin regeneration and suppressing melanin production, it can help improve a dull complexion, making your skin look clearer and more transparent.
It’s not about drastic changes; it’s about bringing your skin back to a healthier, more youthful state naturally. I think that’s why so many people love it.
📝 Example: What 3 Sessions Might Do
After completing a recommended course of 3-4 sessions:
- You might notice your skin feels firmer and bounces back better when you touch it.
- Small lines around your eyes might be less visible.
- Your pores could appear tighter, and your makeup might sit more smoothly.

Practical Information: Cost, Side Effects, and Who Should Consider It 📋
Okay, let’s talk practicalities – like cost and what to expect immediately after. Pricing can vary a bit depending on the clinic and any ongoing promotions, but here’s a general idea based on typical ranges I’ve seen (Note: these are reference prices and can change):
| Product Type | Volume | Target Area | Approx. Price Range (per session) |
|---|---|---|---|
| Rejuran Healer | 2cc | Full Face | ₩88,000 – ₩250,000 |
| Rejuran I | 1cc | Eye Area | ₩85,000 – ₩150,000 |
| Rejuran S | 1cc | Scars | ₩85,000 – ₩150,000 |
Clinics usually recommend 3-4 sessions spaced 3-4 weeks apart for optimal results. After that, maintenance treatments every 6-12 months can help prolong the effects. So, your total cost will depend on how many sessions you do.
Potential Side Effects & Important Considerations ⚠️
It’s important to be aware of what happens right after the procedure. You might see some temporary effects like:
- Embossing: Small, raised bumps at the injection sites (this is common and usually goes away quickly).
- Redness
- Minor bruising
- Swelling
- Slight pain
These are generally normal reactions and tend to disappear naturally within 24 to 48 hours.
Since the ingredient is extracted from salmon, you MUST inform your doctor if you have any seafood or fish allergies before getting the treatment. Though rare, infections or allergic reactions can occur, which is why it’s crucial to have this procedure done by experienced medical professionals.
