Polidesoxirribonucleótido (PDRN)

INCI: Polydeoxyribonucleotide

Fragmentos de ADN de salmón con peso molecular 50–1500 kDa. Activan receptores purinérgicos y estimulan la angiogénesis y la regeneración. La aplicación tópica está limitada por el tamaño molecular.

Evidence by route

Topical application

Very weak or conflicting data.

Topical application has no clinically confirmed efficacy due to the inability of these large molecules to cross the epidermal barrier. PDRN creams may provide surface moisturization as formula excipients, but not through specific PDRN activity.

Injectable

Limited evidence. One RCT or several controlled studies with limitations.

Intradermal PDRN injections for photoaging and atrophic scars are supported by several RCTs and prospective studies. Improvements in skin hydration, tone, and dermal density have been demonstrated. Allergic potential is minimal – salmon protein is absent in purified formulations.
