Can Rejuran Treat Acne Scars — Salmon DNA (PN) · How Many Sessions
What is Rejuran · how much Salmon DNA (PN) helps acne scars · vs Subcision · how many sessions. Dr. Big explains · Clarity Clinic Ratchathewi, near BTS.
“I heard Rejuran helps acne scars — true? Can it replace Subcision?”
Many wonder, because Rejuran is a famous name in Korean and Thai skincare — but the Thai market often overhypes it. This article explains the science: what Rejuran is, how much it helps acne scars, and what it isn’t.
What is Rejuran?
Rejuran (Polynucleotide / PN) = polynucleotide extracted from salmon DNA, injected under the skin to stimulate fibroblasts (collagen-building cells), reduce dermal inflammation, support the skin barrier, and boost hydration. Mechanism: not a filler, doesn’t add volume — it’s a bio-stimulator that prompts the skin to build its own collagen.
Rejuran ≠ filler · Rejuran ≠ Subcision · it’s a “stimulator,” one tool in the kit.
How much it helps acne scars
Per research, Rejuran: ✅ reduces acne scar texture (20–40% in 3–4 sessions) · ✅ reduces inflammation in chronic-acne skin · ✅ increases elasticity · ✅ reduces post-acne redness.
But Rejuran cannot: ❌ cut the fibrous bands (needs Subcision) · ❌ fill very deep scars (needs filler) · ❌ remodel deep structure (needs MNRF, laser).
Rejuran suits as a supplement rather than a replacement for Subcision/MNRF/Laser.
Comparison — Rejuran vs Subcision
| Factor | Rejuran (PN) | Subcision |
|---|---|---|
| Mechanism | Stimulates collagen | Releases bands |
| Result | Smoothness from collagen | Lift from released bands |
| Suits | Mild atrophic scars · texture | Rolling, box scars |
| Not for | Deep ice pick | Ice pick |
| See result | 4–12 weeks | 4–8 weeks |
| Risk | Very low | Low |
| Downtime | Swelling 1–2 days | Swelling 2–3 days |
Combining with other techniques
A common Clarity plan: 1) Subcision releases bands · 2) MNRF stimulates deep collagen · 3) Rejuran boosts collagen in shallower layers · 4) Laser refines texture. Combined: 60–80% improvement in 3–5 sessions.
Pricing in Thailand
Genuine Rejuran (2cc): Healer injection 12,000–18,000 baht · combined with Subcision/MNRF 15,000–25,000 baht.
At Clarity — Rejuran is an optional add-on · assessed per case, priced before deciding · depends on the amount used · not forced · Subcision + MNRF + Laser alone already gives results (5,000 baht/session including every main procedure).
Risks · cautions
Mild swelling 1–3 days · red dots at injection sites (2–7 days) · rare itching/rash. Don’t use if: fish allergy · pregnant/breastfeeding · autoimmune disease · severe active inflammation.
