PDRN and Polynucleotide Therapy in Plainview, NY - The Complete Patient Guide

Clinical overview

Polynucleotide therapy -- marketed under names including Rejuran, PDRN, and PN -- has been a cornerstone of regenerative aesthetics in South Korea and Europe for over a decade, and is now one of the fastest-growing injectable categories in the United States. At Stay Ageless Clinic in Plainview, NY and Center Moriches, Farina Sial, PA, MBA has incorporated PDRN into the regenerative program as a treatment that addresses something most aesthetic injectables do not: the fundamental quality and repair capacity of the skin itself.

What Is Pdrn--

PDRN (PolyDeoxyRiboNucleotide) is a biopolymer extracted from the DNA of salmon sperm (pollock fish gonads). Salmon DNA shares approximately 97% structural homology with human DNA -- meaning the PDRN molecule is recognized and processed by human cells in a manner analogous to the body's own DNA repair signals.

PDRN works through two primary biological mechanisms:

A2A adenosine receptor activation -- PDRN binds to A2A receptors on fibroblasts, triggering an upregulation of VEGF (vascular endothelial growth factor) and collagen synthesis. This stimulates new collagen production, improves microvascular circulation in the treated tissue, and accelerates wound healing and tissue repair.

DNA salvage pathway -- The polynucleotide fragments provide the nucleotide building blocks used in the DNA salvage pathway -- the cellular mechanism by which new DNA is synthesized from recycled components. This reduces the energy cost of cellular repair and accelerates tissue regeneration.

What PDRN Treats

Skin quality improvement -- PDRN produces measurable improvement in skin texture, smoothness, and radiance through progressive collagen stimulation over 4-8 weeks per session. The improvement is cumulative with multiple sessions.

Pore refinement -- Collagen regeneration around pore openings physically reduces pore diameter over time. This is one of PDRN's most clinically consistent results and one of the most requested outcomes at Stay Ageless Clinic.

Fine line reduction -- New collagen fills in the dermal architecture that fine lines form within, producing gradual but genuine structural improvement.

Dark circle and under-eye skin quality -- PDRN improves the vascularity and tissue quality of the under-eye area, reducing the thin, translucent appearance of periorbital skin that contributes to dark circles.

Post-procedure skin repair -- PDRN accelerates recovery after laser treatments, RF microneedling, and chemical peels at Stay Ageless Clinic by activating the tissue repair cascade immediately after treatment.

Skin tone and radiance in darker skin -- PDRN is particularly valuable for Fitzpatrick IV-VI patients who want skin quality improvement without pigmentation risk. Unlike some brightening treatments, PDRN carries no hyperpigmentation risk in darker skin tones.

Rejuran vs PDRN -- What's the Difference--

Rejuran is a branded formulation of PDRN produced by Pharmos Biopharma in South Korea -- the original and most studied polynucleotide product. PDRN is the generic category name. At Stay Ageless Clinic, both Rejuran (the branded original) and high-quality PDRN formulations are available. Farina Sial, PA, MBA discusses the appropriate formulation at consultation based on the patient's skin concerns and treatment goals.

A typical Rejuran/PDRN program involves 4 sessions spaced 2-4 weeks apart, followed by maintenance sessions every 3-6 months. Mild swelling and occasional small injection points are normal and resolve within 24-48 hours.
