Acne scars can be one of the most stubborn and emotionally distressing skin concerns—especially when they persist into adulthood. While laser resurfacing and microneedling have long been go-to options, Korean dermatologists are now increasingly recommending Rejuran Healer—a regenerative injectable using polynucleotides (PN)—for patients seeking smoother, healthier skin with minimal downtime.
This article dives into how Rejuran Healer works on acne scars, what patients can expect from Korean dermatology clinics, and what kind of results are typical based on clinical expertise.
🔬 What Is Rejuran Healer?
Rejuran Healer is an injectable skin rejuvenation treatment containing polynucleotides (PN), which are DNA fragments derived from salmon. These PNs work at the cellular level to:
- Stimulate fibroblasts for collagen regeneration
- Repair the extracellular matrix (ECM)
- Improve skin texture, tone, and elasticity
- Reduce inflammation and promote healing
This makes it highly suitable for treating atrophic acne scars, which are typically caused by collagen loss in the dermis.
🧑⚕️ How Rejuran Healer Helps With Acne Scars (Medically Explained)
Korean dermatologists use Rejuran for acne scars because of its ability to restore dermal structure. Here’s what it does:
1. Boosts Collagen Synthesis
Acne scars often involve a loss of dermal tissue. Rejuran stimulates fibroblasts to rebuild collagen in damaged areas, gradually filling in depressed scars like boxcar and rolling scars.
2. Improves Skin Texture and Elasticity
PNs encourage tissue remodeling, which makes skin firmer and smoother, reducing the visibility of pitted scars and uneven texture.
3. Reduces Post-Acne Redness and Inflammation
For patients with inflammatory or red acne scars, Rejuran’s anti-inflammatory effects help calm the skin and reduce erythema, especially when combined with laser toning.
4. Enhances Wound Healing Post-Acne Procedures
Rejuran is often used in combination with microneedling or fractional laser to accelerate healing and optimize skin recovery, reducing the risk of post-treatment hyperpigmentation or prolonged downtime.
📋 Clinical Treatment Plan for Acne Scars in Korea
Korean clinics often create personalized, multi-session protocols for acne scar patients. A standard Rejuran plan may look like this:
| Stage | Details |
|---|---|
| Initial Consult | Skin analysis using VISIA or OBSERV system to assess scar depth/type |
| 1st Treatment | Full-face or targeted Rejuran microinjections + optional laser/microneedling |
| 2nd Session | 3–4 weeks later to reinforce collagen production |
| 3rd Session | Additional improvement of skin tone and elasticity |
| Maintenance | 1 session every 6 months (optional, based on scar severity and age) |
💡 Pro Tip: Rejuran S—a variant of Rejuran—has a more concentrated formula and is used specifically for depressed acne scars. It’s injected more deeply into the dermis.
🔄 Rejuran vs. Other Acne Scar Treatments in Korea
| Treatment | Strengths | Best For |
|---|---|---|
| Rejuran Healer | Regeneration, anti-inflammation, scar softening | Boxcar, rolling scars, sensitive skin |
| Rejuran S | Focal volume repair for deep, atrophic scars | Deep ice pick or boxcar scars |
| Microneedling (RF) | Collagen induction, minimal downtime | Large pores, shallow scars |
| Fractional CO2 Laser | Resurfacing, collagen boost | Moderate-to-severe pitted scars |
| TCA Cross | Chemical reconstruction of ice pick scars | Ice pick scars |
| Subcision + Rejuran | Releases scar tissue, then repairs it with PN | Tethered or fibrotic scars |
🔍 Before & After: What to Expect in Results
🔸 1 Month
- Improved hydration and skin elasticity
- Slight softening of shallow scars
- Reduced redness

🧑⚕️ Korean dermatologists emphasize patience, as Rejuran is a biological regeneration treatment, not a quick fix.
🩺 What Korean Dermatologists Say
“For acne scars, we prefer Rejuran as a supportive therapy—either as a standalone for mild scarring or combined with lasers or subcision for more severe cases.”
— Dr. Lee J.H., Dermatologist at Seoul Aesthetic & Scar Clinic
“Patients often return after three sessions with noticeable changes—not just to the scar itself, but the entire skin texture improves.”
— Dr. Kim S.Y., Banobagi Dermatology
🧴 Aftercare: Post-Rejuran for Acne Scars
- Use barrier-repair moisturizers (e.g., Aestura, La Roche-Posay)
- Avoid retinoids, acids, and active exfoliants for 7–10 days
- Always wear broad-spectrum SPF
- Avoid facial massage, gym, or saunas for 2–3 days
- Stay hydrated to support skin regeneration
