Quick Answer
Recell PDRN is a Korean-manufactured salmon-derived Polydeoxyribonucleotide concentrate, supplied as 5 × 3 mL vials. PDRN consists of DNA fragments (typically 80–2000 base pairs) that activate adenosine A2A receptors on fibroblasts, triggering collagen synthesis and accelerated tissue repair. Standard protocol is 3–4 sessions at 2–4 week intervals, with maintenance every 4–6 months.
Why This Skinbooster Is Different
PDRN exerts its effect through a specific receptor — adenosine A2A — rather than through pH, hydration, or physical scaffolding. The mechanism is biological signalling at the receptor level. This is what differentiates it from HA-based skin boosters (physical hydration) and from amino-acid cocktails (substrate supply): PDRN supplies the activation signal to fibroblasts directly.
Mechanism of Action
DNA-derived nucleotide fibroblast stimulator. PDRN binds adenosine A2A receptors on dermal fibroblasts. Receptor activation triggers a downstream cascade: fibroblast proliferation, collagen synthesis, neoangiogenesis, anti-inflammatory modulation. The mechanism is biological receptor signalling — distinct from hydration-based or scaffold-based mechanisms.
Frequently Asked Questions
What is PDRN and where does it come from?
PDRN stands for Polydeoxyribonucleotide — a polymer of deoxyribonucleotides (DNA building blocks). The clinical-grade material is extracted and purified from salmon sperm DNA, which has high homology with human DNA. The DNA is fragmented to a 80–2000 base-pair range and purified to medical grade.
Is salmon-derived PDRN safe?
Yes — when sourced from a quality-controlled manufacturer with documented MFDS approval or equivalent regulatory clearance, salmon PDRN is well tolerated. The high homology with human DNA minimizes immunogenic potential. Practitioners should verify batch certificates of analysis on receipt.
How does PDRN actually work?
PDRN binds to adenosine A2A receptors on dermal fibroblasts. Receptor activation triggers a cascade including increased fibroblast proliferation, collagen synthesis, neoangiogenesis, and anti-inflammatory effects. The mechanism is biological signalling at the receptor level, not physical scaffold.
How is Recell PDRN different from Rejuran or Vitaran?
All three are PDRN-containing skinboosters. Rejuran (Pharma Research) and Vitaran are premium Korean brands with strong clinical track records. Recell PDRN is a more accessible option in the same category. Differences exist in concentration, MW distribution, and additional ingredients; concentration and pricing should be evaluated case by case for the specific clinical objective.
Is PDRN the same as PN (Polynucleotide)?
Closely related but not identical. PN is longer-chain DNA fragments; PDRN is shorter-chain. Longer chains (PN) tend to remain in tissue longer with sustained signalling; shorter chains (PDRN) absorb faster with broader topical applicability. Recell PDRN is the shorter-chain variant.
Can it be used for acne scars?
Yes — atrophic acne scars are one of the strongest published indications for PDRN. The mechanism (fibroblast activation, collagen synthesis, anti-inflammatory action) directly addresses the underlying tissue deficit. Typical protocol is 4–6 sessions for established acne scarring.
How many sessions before patients see results?
Improvement typically becomes visible from 2–4 weeks after the second session. The standard 3–4 session course produces cumulative benefit observed at 8–12 weeks after the final session. Patients with established scarring require longer courses (4–6 sessions).
Is cold-chain shipping required?
Yes. PDRN should be maintained at 2–8 °C during transit and storage. Brief temperature excursions (24–48 hours above 8 °C) are generally tolerated, but prolonged warm exposure degrades the DNA fragments. Confirm cold-chain handling on receipt of each delivery.
Can it be combined with HA filler in the same session?
Yes — sequential injection in different anatomical planes is common. Most protocols administer PDRN first (superficial dermis), then HA filler at deeper level. Avoid mixing in the same syringe. Some practitioners stage the procedures over different visits for clarity of attribution.
Can a patient with shellfish allergy use salmon PDRN?
Shellfish allergens are typically tropomyosin proteins. Salmon PDRN is purified DNA, not protein, so cross-reactivity is biologically implausible. However, formal patient counselling and review of allergy history should be conducted before the first session; documented severe fish or seafood allergy warrants caution and individual assessment.
