Science
Mechanism of Action
Forms a thin, hydrophobic barrier on skin through its three-component structure: cyclohexylmethacrylate provides structural rigidity, ethylhexyl acrylate adds flexibility, and butyl dimethicone acrylate contributes silicone-like water repellency and smooth feel. This creates a breathable film that locks active ingredients onto skin while preventing wash-off from water and sweat.
