Polynucleotide skincare represents one of the most exciting frontiers in aesthetic medicine. Originally developed for clinical use, PN-based products have now become accessible for at-home use, delivering professional-grade skin regeneration without the clinic visit.

What are Polynucleotides?

Polynucleotides are fragments of DNA derived from salmon or trout sperm, carefully purified and processed for cosmetic and medical use. These DNA fragments interact with our skin cells to stimulate natural repair and regeneration processes, triggering the production of collagen, elastin, and hyaluronic acid.

How Do PN Products Work?

When applied topically, polynucleotides act as “biostimulators” — they signal to fibroblast cells in the dermis to ramp up their natural production of extracellular matrix proteins. The result is measurably firmer, more elastic skin with reduced appearance of fine lines and improved texture.

Clinical Evidence

Multiple clinical studies have demonstrated the efficacy of PN-based formulations. A 2022 study in the Journal of Cosmetic Dermatology showed significant improvement in skin elasticity, hydration, and surface smoothness after 12 weeks of twice-daily PN serum application.

Our Top PN Products
