Common Name(s): Acetyl hexapeptide-1,hexapeptide signal peptide,anti-aging active

CAS Number: N/a

DESCRIPTION

What It Does: Stimulates collagen i, iii, and iv synthesis, inhibits collagen-degrading mmp-1 and mmp-3, and promotes dermal matrix density for firmer, more elastic skin with reduced wrinkle depth.

Why It's Used: Provides precision receptor targeting (tgf-ฮฒ, egf, or integrin receptors) that broad-spectrum botanicals cannot replicate, with clinical-grade purity and quantified in-vitro efficacy at 1โ€“5000 ppm.

How It Works: The hexapeptide amino acid sequence binds specific receptors activating map kinase or smad signalling cascades, upregulating col1a1, col3a1, and fibronectin genes while downregulating mmp-1.

Typically Found In: Anti-aging serums,collagen actives
