Mechanism of Action (MOA)
Tetrapeptide-4 is a synthetic signaling peptide composed of four amino acids. It is designed to interact with skin cells by modulating cellular communication pathways, particularly those involved in the extracellular matrix. By supporting the expression of key proteins such as collagen and fibronectin, Tetrapeptide-4 helps optimize the skin's structural environment. This peptide may also influence the activity of enzymes linked to matrix turnover, contributing to enhanced skin condition and resilience.
Tetrapeptide-4 can be incorporated into various cosmetic formulations to enhance product versatility and sensory appeal.
