Matrixyl®

The tradename for palmitoyl pentapeptide-3, a man made precursor to collagen 1. It is five amino acids linked in a fatty acid and structurally related to the c portion terminal of collagen 1. Claims to challenge retinal as a treatment for photo damaged skin without the irritation. Manufacturer studies show that it stimulates production of collagen and hyaluronic acid, key components of the extracellular matrix, but there is little in the way of independent evaluation.
