Common Name(s): Dipeptide-34,dipeptide-34,two-residue bioactive,minimal anti-aging active

CAS Number: N/a

DESCRIPTION

What It Does: Provides targeted anti-aging receptor activation for collagen synthesis or mmp inhibition — the two-residue sequence providing excellent formulation stability and sc penetration from the low mw.

Why It's Used: Dipeptides provide the simplest effective peptide anti-aging agents — two-residue sequences at the minimum viable pharmacophore provide maximum stability and penetration at minimum molecular weight.

How It Works: Dipeptide receptor binding: the two-residue sequence maintains the minimum pharmacophore for receptor recognition while providing optimal stability (resistant to most tissue dipeptidases due to non-natural amino acid or blocking groups). low mw (<300 da) enables sc penetration without lipid anchoring.

Typically Found In: Anti-aging serums,targeted actives

SCIENTIFIC NOTE

Dipeptide stability advantage: two-residue sequences are resistant to aminopeptidase if n-terminally blocked (acetyl, formyl) or contain d-amino acids — the specific modification determines in-skin half-life.
