Science
Mechanism of Action
This ingredient operates via its unique structure, featuring a water-loving glutamate head group and an oil-anchoring stearoyl tail. This amphiphilic nature enables it to form lamellar gel structures, enhancing emulsion stability, increasing viscosity, and improving the compatibility and penetration of other active ingredients. As a surfactant, it lowers water's surface tension, facilitating the removal of oils and impurities from the skin.
