Myristoyl tripeptide-5
INCI name · myristoyl tripeptide-5
In short
Myristoyl Tripeptide‑5 is a lipid‑modified form of Tripeptide‑5 designed to penetrate more effectively through the skin’s lipid layers. It supports smoother‑looking texture and elasticity.
What it is
Myristoylated (C14 fatty acid) form of tripeptide-5 that improves skin penetration through the stratum corneum lipid matrix; the lipid tail tethers the signal peptide within the lipid-rich intercellular space, increasing residence time near fibroblasts; targets collagen I and fibronectin synthesis pathways; formulation benefit over unmodified tripeptide-5 is better substantivity in rinse-off contexts.
