Science
Mechanism of Action
This peptide acts as a signaling molecule, actively stimulating the dermal synthesis of crucial extracellular matrix components, including collagen, elastin, and fibronectin. This regenerative action helps to counteract skin aging by improving texture, increasing firmness, and enhancing elasticity. Additionally, SH-TETRAPEPTIDE-1 possesses antioxidant benefits, supporting skin hydration and strengthening the skin barrier function.

Stability
SH-TETRAPEPTIDE-1 powder should be stored sealed at -80°C for up to 2 years or -20°C for up to 1 year, protected from moisture. In solution, aliquoting and storage at -80°C for 6 months or -20°C for 1 month is recommended to prevent degradation from freeze-thaw cycles. The acetylation of the N-terminal end, as seen in Acetyl sh-Tetrapeptide-1, is known to enhance its stability and efficacy in cosmetic applications.
