If you've traveled in Europe or South Korea and talked to people about skin treatments, you've probably heard about polynucleotides — sometimes called PDRN (polydeoxyribonucleotide), PN, or by brand names like Rejuran, Nucleofill, or Plinest. The treatment is widely established in these markets and is now gaining meaningful traction in the US. For men interested in skin quality improvement that goes beyond what Botox and standard HA fillers offer, polynucleotides represent one of the most scientifically credible options available.
What Polynucleotides Actually Are
Polynucleotides are long chains of DNA fragments derived primarily from salmon or trout sperm DNA (which is highly compatible with human tissue). When injected into the skin, these DNA fragments bind to specific cellular receptors that trigger a wound-healing-like regeneration response. The fibroblasts in your skin upregulate collagen and elastin production, new capillaries form (improving circulation and therefore nutrient delivery), and the skin's overall structural architecture improves. The key distinction from HA fillers: polynucleotides don't add volume. They improve the biological function and structure of the tissue itself.
How PDRN Works on Male Skin

Male skin is thicker and has higher collagen density, but also typically receives more cumulative UV damage (due to historically lower SPF use), ages more rapidly from chronic stress-related cortisol exposure, and experiences testosterone-driven changes that accelerate certain types of collagen degradation in the 40s. Polynucleotides address the underlying biology — stimulating new collagen formation, improving microcirculation, and reducing the inflammatory processes that accelerate skin aging. For men with chronic sun damage, stress-driven skin aging, or who've had periods of poor sleep and nutrition that show in the skin, PDRN gets at the root causes rather than masking symptoms.
Polynucleotides are particularly effective for the under-eye area in men — the delicate periorbital skin that shows fatigue, sun damage, and early aging most visibly. Multiple trials show PDRN improves under-eye skin quality better than HA fillers alone.
Key Treatment Areas for Men
Where polynucleotides deliver the clearest results for male patients:
- •Under-eye area — perhaps the strongest indication; PDRN improves the thin, easily-damaged periorbital skin better than almost any other treatment
- •Overall facial skin quality — whole-face protocols address dullness, uneven texture, and early laxity
- •Acne scarring — strong evidence for improving atrophic (indented) acne scars in men who've had significant breakouts
- •Sun-damaged skin — helps reverse the accumulated effects of UV exposure by stimulating new collagen in UV-damaged tissue
- •Neck skin — an often-overlooked area in men where early laxity and texture changes respond well to PN treatment
- •Scalp (for hair health) — PDRN injected into the scalp has been shown to improve hair follicle function, though this is a separate protocol from facial skin treatment

Polynucleotide treatments involve multiple small injections across the target area using a very fine needle. The process takes 30-45 minutes. There's typically mild redness and small injection papules (bumps) for 24-48 hours after treatment. Results build gradually — most men see initial improvement in skin hydration and texture within 2-3 weeks, with continued improvement over 2-3 months as new collagen matures. The standard protocol is 3-4 sessions spaced 2-4 weeks apart, followed by maintenance every 6-12 months. Unlike fillers or Botox, the results of polynucleotides are permanent in the sense that new collagen, once formed, doesn't disappear when the product metabolizes — though ongoing maintenance is needed to continue improving and to address ongoing aging.
Polynucleotides vs PRP, Profhilo, and Exosomes
The biologics-based regenerative treatment category now has four major options for men: PRP, Profhilo, exosomes, and polynucleotides. PRP uses your own concentrated growth factors — good but variable based on your biology. Profhilo is a high-concentration HA that spreads and hydrates while stimulating collagen. Exosomes are cell-signaling vesicles that trigger regenerative responses. Polynucleotides directly stimulate fibroblast activity through DNA-level cellular communication. Each has distinct advantages. Many practitioners are now combining them — Profhilo for hydration and laxity, PDRN for under-eye and acne scar treatment, exosomes post-microneedling for recovery. For men choosing one starting point, PDRN has the strongest clinical evidence base of the biologics-adjacent options and is the most widely established outside the US.

Polynucleotides are becoming more widely available at aesthetic practices in major US markets. A single session typically costs $400-900 depending on the market and how much area is treated. Full treatment protocols (3-4 sessions) run $1,500-3,500. Many practices in NYC, LA, Miami, and Chicago now offer PDRN services; availability in smaller markets is less consistent. When evaluating providers, ask specifically which PN product they use — Rejuran, Nucleofill, and Plinest are among the most clinically validated brands. The injectable PDRN market has quality variability; choose providers who use established pharmaceutical-grade products.
