Key Tetrapeptide-21 Skin Firmness Benefits
● Boosts collagen production up to 2.5x

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.
