Science
Mechanism of Action
This synthetic matrikine lipopeptide operates by signaling dermal cells to significantly enhance the expression and production of crucial extracellular matrix components, including collagen types I, III, IV, and VI, along with fibronectin. Furthermore, it reinforces dermal cell-to-matrix adhesion by boosting the production of structural proteins such as Cofilin, α-Actinin-1, Actin, Talin, and Integrins α2/β1. Studies confirm its impact on two primary biological pathways: one responsible for regulating collagen synthesis and another influencing the actin cytoskeleton. It also upregulates transcription factors like FOXO and stress-response proteins such as sestrins, both linked to cellular longevity and collagen regulation, as evidenced by increased gene and protein levels of collagen and fibronectin in in vitro fibroblast tests.
