Common Name(s): Acetyl heptapeptide-4,acetyl heptapeptide-4,acetyl-stabilised heptapeptide,anti-aging signal peptide

CAS Number: N/a

DESCRIPTION

What It Does: Stimulates fibroblast collagen i, iii, iv synthesis and inhibits mmp-1/mmp-3 collagen degradation — providing clinically measurable wrinkle reduction and skin firmness improvement with regular use.

Why It's Used: Precision peptide pharmacology provides mechanism-based anti-aging efficacy — the defined sequence targeting specific receptors (tgf-beta, egf, integrin) enables quantifiable binding kinetics and reproducible clinical outcomes.

How It Works: Peptide sequence binds cognate receptor activating map kinase or smad cascades → col1a1/col3a1 upregulation and mmp-1/mmp-3 downregulation. spps synthesis provides >98% sequence purity for reproducible receptor binding.

Typically Found In: Anti-aging serums,collagen products

SCIENTIFIC NOTE

Peptide sequence purity above 98% is essential for reliable receptor binding — single amino acid substitution can eliminate binding selectivity. spps synthesis and hplc purification are the quality standards for efficacious cosmetic peptides.
