Benefits of sh-Polypeptide-9

A premium, biotech-derived growth-factor active used to support the appearance of renewed skin and healthy hair.

• Scalp Environment Appearance: Perifollicular microcirculation is associated with a healthy hair-growth environment, so VEGF-style actives are prized in scalp serums (for the look of a healthy scalp).
• Well-Nourished Look: Supports the appearance of a well-supplied, vital complexion.
• Complements the Complex: Pairs with the renewal-supporting FGF and IGF growth factors.
• Premium Biotech Active: A recombinant “synthetic human” signal protein made by fermentation.

How It Works

sh-Polypeptide-9 is a recombinant analog of VEGF, the signal protein that directs vascular endothelial cells to build and maintain microvasculature. Because perifollicular blood supply is linked to a healthy hair-growth environment, VEGF-type actives are common in scalp serums. As with all large growth-factor proteins, penetration through intact skin is inherently limited, so stabilization and delivery are the real formulation challenge and topical efficacy continues to be studied — this is an active, biologically-grounded ingredient, not a finished product claim.

Formulating with sh-Polypeptide-9

Used at very low levels in the water / cool-down phase of serums and essences, typically as part of a growth-factor complex. It is heat- and shear-sensitive, so add it late and keep it cool; prioritize a stabilizing, delivery-focused system and confirm compatibility and preservation in the finished formula.
