Science
Mechanism of Action
Its efficacy stems from a sophisticated mode of action targeting key biological processes. The ingredient actively inhibits collagenase and elastase, enzymes responsible for the degradation of collagen and elastin, thereby supporting skin firmness and reducing wrinkle appearance. It further promotes the upregulation of protein markers critical for maintaining tight junctions, which are essential for robust skin barrier function. Additionally, it exhibits antimelanogenesis properties by inhibiting tyrosinase and regulating associated proteins, effectively working to diminish hyperpigmentation and even skin tone.
