Tetrapeptide-21

(Synonyms: Tetrapeptide21, GEKG peptide) Copy Product Info

Tetrapeptide-21 (GEKG peptide) is a bioactive peptide composed of four amino acids that effectively enhances the activity of human dermal fibroblasts. It upregulates the expression of key extracellular matrix (ECM)-related genes and promotes the synthesis of ECM proteins, including type I collagen, hyaluronan synthase 1, and fibronectin. Due to its anti-wrinkle and skin elasticity-improving effects, Tetrapeptide-21 has been reported as an ingredient in cosmetic products.
