Mechanism of Action
Acetyl Tetrapeptide-5 works by modulating microvascular permeability and inhibiting glycation reactions that damage collagen and elastin. It enhances the elasticity and compactness of the skin by improving the functionality of structural proteins in the extracellular matrix. The peptide also promotes water retention and circulation, leading to visibly smoother and firmer skin—particularly effective in the periorbital (eye) area.
