Key Benefits of PDRN Powder:
Natural Origin: Derived from trout sperm, it is a bio-sourced ingredient. Multi-action Mechanism: It activates the purinergic A2A receptor, triggering the cellular “rescue pathway” for repair. It upregulates VEGF (Vascular Endothelial Growth Factor), promoting angiogenesis and microcirculation. It inhibits MITF and tyrosinase, reducing melanin production at the source. Excellent Safety Profile: Has a proven safety record.PDRN Powder (Polydeoxyribonucleotide Powder) offers Core Functional Effects:
- Anti-aging: Activates the purinergic A2A receptor, triggers cellular repair pathways, restores the skin’s youthful appearance, and improves fine lines and sagging.
- Promotes wound healing: Upregulates VEGF to promote angiogenesis and microcirculation, accelerates skin barrier repair, and shortens the healing cycle.
- Acne Scar Improvement: Repairs depressed acne scars and hyperpigmented acne marks; combines wound healing and melanin inhibition to smooth skin texture.
- Melanin Inhibition: Inhibits MITF and tyrosinase activity, blocking melanin synthesis at the source to brighten the skin and fade pigmentation.
- Promotes hair regrowth: Improves blood supply to hair follicles, stimulates follicles to transition from the telogen phase to the anagen phase, increases hair density, and helps address hair loss.
