Science
Mechanism of Action
This advanced tripeptide functions by signaling the skin to activate its endogenous repair mechanisms, primarily stimulating collagen synthesis to improve skin architecture. The citrulline moiety contributes potent antioxidant capabilities, safeguarding cellular integrity by complexing metal ions, such as Cu(II), thereby inhibiting radical degradation and protecting DNA from reactive oxygen species generated by the Fenton reaction. This multifaceted action strengthens the skin barrier, promotes vascular health, and facilitates skin renewal, culminating in improved firmness, elasticity, and overall skin health.
