Science
Mechanism of Action
This ingredient functions as a versatile amphoteric surfactant, exhibiting both positive and negative ionic charges, which allows for stable performance across a wide pH range. It works by reducing the surface tension within formulations, effectively lifting dirt, excess oil, and other impurities from the skin. Concurrently, it contributes notable emollient properties and enhances the skin's intrinsic capacity to retain hydration. Furthermore, the shea butter component intrinsically offers beneficial anti-inflammatory and antioxidant attributes.
