Tripeptide KMK is a new highly efficient bio-mimetic peptide. It belongs to the family of peptides termed matrikines. Matrikines peptides are identical to fragments of extracellular matrix components. Therefore, they act as buffering agents and are able to modulate the activities of cells. The Tripeptide KMK stimulates the synthesis of six major structural components of the dermal matrix: collagen I, collagen III, fibronectin, hyaluronic acid, laminin, collagen IV and ensures better construction of tissue. Tripeptide KMK fills wrinkles from both the forehead and crow's feet for a visibly smoother and firmer skin.
