Matrixyl

Matri-xyl, also known as as palmitoyl pentapeptide-4 or palmitoyl pentapeptide-3, is a synthetic peptide currently under scientific investigation for its potential to stimulate collagen production in the skin. It is classified as a matrikine – a messenger peptide that may regulate cell activities by interacting with their specific receptors.

Matrixyl

Collagen is a protein that is considered to support flexibility and structural integrity in the extracellular matrix of the skin. The conjugation with the palmitoyl introduces the potential for more consistent delivery across the skin and better stability to skin proteases.
