Tetrapeptide-21
Peptide
Peptides are the amino-acid chains that help your skin produce proteins such as collagen.
Explained
Tetrapeptide-21 is a signal peptide. It helps boost collagen, hyaluronic acid, and fibronectin.
Fibronectin is a protein found in our skin's extracellular matrix that plays a role in cell adhesion, tissue repair, and wound healing.
Tetrapeptide-21 works by mimicking skin-protein breakdown signals, telling the skin to produce new structural proteins like collagen.
Preliminary studies show it works better than matrixyl and produced twice the amount of collagen in lab tests.
