What Is Tetrapeptide-21?

Tetrapeptide-21 is a bioactive peptide with the sequence Gly-Glu-Lys-Gly (GEKG), designed to replicate the natural protein fragments found in youthful skin. It acts by stimulating gene expression in dermal fibroblasts enhancing the production of structural proteins and skin-repair molecules.

Tetrapeptide-21 vs Matrixyl Wrinkle Reduction

While Matrixyl is widely known for stimulating collagen, Tetrapeptide-21 offers a broader boost by increasing not only collagen but also hyaluronic acid and fibronectin.
