Myristoyl tripeptide-31
INCI name · myristoyl tripeptide-31
In short
Myristoyl Tripeptide‑31 is a lipidated peptide positioned to help soften the look of expression‑prone areas. Research is limited, but it is designed to influence surface muscle‑tension signalling for a smoother appearance.
What it is
Lipidated peptide proposed to act as a topical muscle-relaxant analogue; the myristoyl tail enables skin penetration and the tripeptide component is designed to interact with the neuromuscular junction signalling cascade, analogous to the mechanism of acetyl hexapeptide-3 (Argireline) but through a distinct molecular target; primary interest is reducing dynamic tension in expression-prone areas; limited independent clinical data. Efficacy claims rely heavily on proprietary supplier studies.
