Common Name(s): Acetyl tetrapeptide-71,acetyl tetrapeptide-71,acetyl-stabilised signal peptide,anti-aging bioactive
CAS Number: N/a
DESCRIPTION
What It Does: Stimulates fibroblast collagen synthesis and inhibits mmp-mediated collagen degradation โ clinically measurable wrinkle reduction and skin firmness at ppm concentrations.
Why It's Used: Precision peptide sequence-receptor pharmacology enables mechanism-based anti-aging claims โ defined amino acid sequence targeting specific receptors (tgf-ฮฒ, egf, integrin) with quantifiable binding kinetics.
How It Works: Peptide receptor binding โ map kinase/smad cascade โ col1a1/col3a1 upregulation + mmp-1/mmp-3 downregulation. spps synthesis provides >98% purity for reproducible receptor binding.
Typically Found In: Anti-aging serums,collagen products
