Polynucleotides vs. Hyaluronic Acid: Which Regenerative Therapy is Right for You?

With the explosive rise of regenerative aesthetics, patients often ask whether they should opt for traditional hyaluronic acid skin boosters or embrace next-generation polynucleotides (PDRN). While both treatments stimulate healthier skin, their physiological mechanisms are fundamentally distinct.

Hyaluronic Acid: The Ultimate Hydrophilic Sponge

Hyaluronic acid is renowned for its miraculous water-binding capacity—holding up to 1,000 times its molecular weight in moisture. When injected as a bioremodeler (such as Profhilo), it floods interstitial spaces with hydration, providing immediate plumpness and smoothing fine superficial crepiness.

Polynucleotides: The Cellular DNA Communicator

Polynucleotides, by contrast, are polymer chains of nucleotides extracted and purified from trout or salmon gonadal DNA. They do not merely hold water; they bind directly to cell surface receptors (CD39, CD73, and Adenosine A2A receptors) to actively command fibroblasts to synthesize fresh Type I collagen, down-regulate inflammatory cytokines, and stimulate vascular micro-perfusion.

For fragile, thin tissue—most notably around the eyes—polynucleotides provide unmatched regenerative healing without any danger of puffiness.
