Common Name(s): Biotinoyl tetrapeptide-51,biotinoyl tetrapeptide-51,biotinoyl signal peptide or amino acid active,anti-aging bioactive

CAS Number: N/a

DESCRIPTION

What It Does: Stimulates collagen synthesis, inhibits mmp-mediated matrix degradation, or provides amino acid-specific skin metabolic support โ€” delivering measurable anti-aging benefit at ppm concentrations.

Why It's Used: Precision sequence-receptor pharmacology enables mechanism-based anti-aging claims โ€” defined amino acid sequence targeting specific receptors with quantifiable binding kinetics.

How It Works: Peptide receptor binding โ†’ kinase cascade โ†’ col1a1/col3a1 upregulation + mmp-1/mmp-3 downregulation. biotin conjugation supports hair keratin biosynthesis through carboxylase cofactor activity.

Typically Found In: Anti-aging serums,collagen products

SCIENTIFIC NOTE

Conjugated peptides provide dual mechanism: the peptide sequence provides receptor-mediated collagen synthesis stimulation while the aromatic/vitamin conjugate adds independent antioxidant or metabolic cofactor activity.
