Science
Mechanism of Action
This advanced peptide operates by precisely binding to specific receptors on endothelial cells, initiating a cascade that promotes angiogenesis—the critical formation of new micro-blood vessels. This process significantly enhances microcirculation within the skin, ensuring a robust delivery of essential nutrients and oxygen to the dermal layers, which is crucial for optimal cellular function. Furthermore, SH-Polypeptide-9 stimulates fibroblast cells, fostering collagen production, cell growth, migration, and aiding in tissue repair. This comprehensive action leads to improved skin hydration, elasticity, and a visible reduction in the signs of aging.

Formulation
Stability
Growth factors, including SH-Polypeptide-9, are susceptible to destabilization in acidic environments, which can compromise their efficacy. For maximal activity, it is recommended to apply acidic formulations first, allowing them to absorb fully before applying products containing this peptide. Research suggests that encapsulation techniques, such as double-layer encapsulation, can enhance both the stability and biological activity of this ingredient.

Safety
Safety Profile
While a specific safety assessment for SH-Polypeptide-9 by the Cosmetic Ingredient Review (CIR) Expert Panel indicates 'insufficient data', general categories of proteins and peptides have typically been deemed safe. The Environmental Working Group (EWG) identifies SH-Polypeptide-9 with 'LOW' concern for cancer, allergies & immunotoxicity, and developmental and reproductive toxicity. The European Commission's CosIng database lists 'BARLEY SH-POLYPEPTIDE-9' as a skin conditioning agent without major restrictions. However, due to its VEGFA-like activity, individuals with psoriasis should avoid products containing this ingredient, as it may exacerbate their condition. Use on sunburned skin or after high doses of UV radiation is also not recommended.
