What Is Myristoyl Tripeptide-31?
Myristoyl Tripeptide-31 is a three-amino-acid peptide modified with myristic acid, a 14-carbon fatty acid that enhances skin penetration. This lipid modification allows the peptide to effectively cross the skin barrier and reach target cells.
The peptide supports skin rejuvenation processes by signalling cells involved in maintaining skin structure and function. It represents the ongoing advancement in peptide delivery technology.
