BARLEY SH-POLYPEPTIDE-9.

Valuable CAS 127464-60-2 / SKIN CONDITIONING

A cutting-edge, plant-derived growth factor that serves as a bio-identical match to human Vascular Endothelial Growth Factor (VEGF). This precision polypeptide is engineered to revitalize the skin's internal support network, making it a cornerstone for advanced regenerative and anti-aging therapies.

cell-communicating ingredient skin conditioning angiogenesis stimulant barrier repair

Science

It functions by stimulating angiogenesis, the biological process of forming new micro-capillaries. By improving dermal microcirculation, it ensures a superior delivery of oxygen and vital nutrients to fibroblasts, which in turn accelerates cellular proliferation, wound healing, and the synthesis of essential structural proteins like collagen and elastin.

Key findings

  1. 01 Clinical trials utilizing a 3% concentration demonstrated a 38% reduction in the depth of wrinkles and a 32% increase in elasticity within a 14-day window.
  2. 02 Immediate hydration metrics showed an 83% increase following topical application.
  3. 03 Research indicates a significant upregulation of barrier-essential proteins, specifically Filaggrin and Involucrin, when utilized in synergistic peptide blends.
