Exostems HA-PDRN Polynucleotide Renewal Concentrate

EXOSTEMS HA-PDRN is built around PDRN (Polydeoxyribonucleotide, Sodium DNA), one of the most rigorously studied regenerative actives in modern aesthetic medicine, with peer-reviewed clinical data across photoaging, wrinkle depth reduction, tissue repair, and angiogenesis. PDRN operates via the purinergic A2 receptor pathway: activation stimulates cellular proliferation through the DNA salvage pathway, accelerates fibroblast activity, improves capillary integrity in photodamaged dermis, and measurably reduces established wrinkle depth. Its tissue-repairing and anti-inflammatory properties make it uniquely suited to immediate post-procedure application, where conventional actives are contraindicated. Sodium Hyaluronate provides complementary ECM hydration and structural volume restoration. Niacinamide (Vitamin B3) adds a third independent mechanism: inhibition of melanosome transfer from melanocytes to keratinocytes, unifying tone and addressing UV-induced pigmentation concurrently with tissue repair. The intentionally minimal INCI reduces reactive and sensitisation risk in compromised skin, and a single session delivers regeneration, hydration, and luminosity simultaneously.
