Have you ever looked in the mirror and felt totally frustrated by those stubborn little dents left behind by old breakouts? 😔 I completely understand. To be honest, dealing with pitted acne scars can be a massive confidence killer. Trying to cover them up with makeup often feels like a losing battle—sometimes foundation just settles into the pits and makes them look even more obvious, doesn’t it?
If you’ve been searching for a way to truly heal and smooth out your skin from the inside, rather than just peeling off the top layers with harsh chemicals, you are in the right place. Today, I want to talk about a game-changer in the world of skin regeneration: Rejuran S. It’s a treatment that has been making massive waves in K-beauty and dermatological clinics worldwide. Let’s dive in and see if this is the miracle your skin has been waiting for!
What Exactly is Rejuran S? 🤔
You might have already heard of \”Rejuran Healer,\” the famous salmon DNA injection that gives you that coveted, glowing \”glass skin.\” Well, Rejuran S is its highly specialized sibling. The \”S\” literally stands for Scar. It is specifically formulated to treat depressed scars, acne scars, and localized areas with volume loss.
Just like the original Healer, Rejuran S is comprised of PN (Polynucleotides) extracted from wild salmon DNA. Why salmon, you ask? Because their DNA structure is remarkably similar to human DNA, making it highly biocompatible and very safe for our bodies! However, what makes the \”S\” version special isn’t just the DNA—it’s the texture.
Rejuran S has a much higher viscosity (thickness) than regular Rejuran. This allows it to act like a sturdy physical scaffold directly under a depressed scar, physically lifting it up while simultaneously stimulating intense collagen production to rebuild the damaged skin tissue!
How Does It Actually Work? 🧬
Imagine a deflated mattress. If you just iron the sheets on top, the dip is still there. You need to stuff the inside to make it flat again. That is exactly what Rejuran S does. When injected directly under a pitted acne scar, the thick gel immediately plumps up the depression.
But the real magic happens over the next few weeks. The Polynucleotides act as cellular \”building blocks,\” sending strong signals to your skin cells (specifically fibroblasts) to wake up and start producing fresh collagen and elastin. Over time, the injected gel is safely absorbed by your body and gracefully replaced by your own natural, healthy tissue. It isn’t just a temporary filler; it is a permanent skin regeneration process!

The Rejuran Family: Which One Do You Need? 📊
If you are confused by the different types of Rejuran available at the dermatologist’s office, you certainly aren’t alone! I think it’s crucial to know which one targets your specific skin concern so you don’t waste your time or money. Here is a handy comparison table to clear things up.
| Product | Target Area | Viscosity | Primary Benefit |
|---|---|---|---|
| Rejuran Healer | Full Face | Medium | Overall skin texture, hydration, anti-aging |
| Rejuran S | Acne Scars / Dents | High (Thick) | Volume restoration, deep scar healing |
| Rejuran I | Under Eyes | Low (Thin) | Dark circles, fine lines around delicate eye area |
The Treatment Process: What to Expect 👩⚕️
Going in for any needle-based procedure can be a bit intimidating, right? Let me walk you through what generally happens so you can feel totally prepared. First, your face is thoroughly cleansed, and a strong numbing cream is applied for about 30 to 45 minutes to maximize comfort.
The doctor will then carefully map out your depressed scars. Because Rejuran S is quite thick, it’s typically injected using a tiny needle directly into the base of each individual scar. In many advanced clinics, doctors combine this with a procedural technique called Subcision. This is where they use a specialized needle to break the tough fibrous bands that are physically pulling the scar downward, and then immediately fill that new empty space with Rejuran S to prevent the bands from reattaching. It’s a truly fantastic, synergistic combo!
I won’t sugarcoat it—Rejuran injections are known to be quite \”spicy\” (painful)! Because the substance is thick and has a specific pH level, it stings as it goes in. Also, expect \”embossing\” (little raised bumps that look like mosquito bites) at the injection sites for 2 to 7 days. Plan your social calendar accordingly!

Practical Example: The Ultimate Scar Protocol 📚
To give you a realistic idea of how this treatment works in real life, let’s look at a common clinical case study.
📝 Example: Sarah’s Rolling & Boxcar Scars
- The Problem: Sarah (28) had deep rolling and boxcar scars on her cheeks resulting from severe teenage cystic acne. Previous laser treatments alone weren’t lifting the deepest pits.
- The Strategy: Her dermatologist recommended a combination of CO2 Fractional Laser + Subcision + Rejuran S injections.
The Process & Result
1) Month 1-3: Sarah received Subcision combined with Rejuran S injected precisely into the deepest scars once a month.
2) Month 4: The scaffolding effect truly worked! The depressions lifted by about 60-70%, and the collagen remodeling vastly improved her overall skin texture.
→ Conclusion: Rejuran S acts as the perfect \”fertilizer and soil\” when combined with treatments that actively break down old, stubborn scar tissue.
