Similarly to copper peptides, Matrixyl stimulates the lower layers of the skin to heal themselves, thus accelerating the healing of wounds. Cells called fibroblasts are responsible for knitting together wounds of the skin. Palmitoyl Pentapeptide-4 stimulates the "matrix" layers in the skin -- primarily collagen and fibronectin. When stimulated, the skin produces more collagen. Loss of collagen is what leads to thinning skin and the wrinkling of newly inelastic skin. Matrixyl helps to counteract this natural part of the aging process.

Function of Palmitoyl Tetrapeptide-4

Palmitoyl Tetrapeptide-4 mimics the activity of DHEA, the youth hormone that functions to reverse IL-6 over-production, and therefore reduce the aging symptoms as well as the phenomenon of immunosenescence. Palmitoyl Tetrapeptide-4 can enhance the functions in a variety of skin care and color cosmetic formulation.
