Hexapeptide-10 is a synthetic peptide composed of six amino acids, with the sequence Tyr-D-Ala-Gly-Phe-Leu-Arg. It is a structural analog of the endogenous neuropeptide met-enkephalin, designed to modulate neurogenic inflammation and sensory nerve activity in the skin. The D-alanine residue at position 2 enhances stability against enzymatic degradation, while the C-terminal arginine contributes to its hydrophilic character and receptor interaction.
As a cosmetic ingredient, Hexapeptide-10 is typically supplied as a white to off-white powder with high purity, often stabilized with palmitoyl or acetyl groups to improve skin penetration and half-life. It is produced via solid-phase peptide synthesis and purified by HPLC to ≥95%. The peptide is soluble in water and polar organic solvents, making it suitable for incorporation into a range of topical formulations.
In the personal care industry, Hexapeptide-10 is used in anti-aging and soothing products targeting sensitive or reactive skin. It is believed to reduce the release of pro-inflammatory neuropeptides such as substance P and CGRP, thereby calming the skin and reducing redness and discomfort. Its mechanism of action and good safety profile make it a valuable active for products aimed at neurocosmetic benefits.
Hexapeptide-10 features a linear six-amino acid chain with a molecular weight of approximately 762.9 g/mol. The presence of D-alanine confers resistance to peptidases, while the arginine residue provides a positive charge at physiological pH, enhancing interaction with negatively charged cell membranes. The peptide is highly soluble in water and exhibits good stability when stored under recommended conditions.
