Science
Mechanism of Action
This peptide operates through several distinct pathways to bolster skin health. It specifically targets and inhibits UV-induced inflammation by reducing the expression of pro-inflammatory cytokines and preventing UV-induced matrix metalloproteinase-1 upregulation. Furthermore, Tetrapeptide-16 acts as a competitive inhibitor of TRAF6 binding, thereby effectively blocking the transmission of inflammatory signals. Beyond its direct anti-inflammatory actions, it stimulates collagen synthesis, aids in repairing compromised skin, improves microcirculation to lessen pigmentation, and enhances lymphatic drainage to diminish puffiness. It also supports the skin's intrinsic moisture retention capabilities and reinforces its natural protective barrier function.
