Science
Mechanism of Action
This ingredient functions as an effective emollient, providing significant lubricity and contributing to skin smoothness, tonicity, and nutrition by actively hydrating and softening the skin's surface. As a non-ionic surfactant, it aids in cleansing, foam generation, and emulsification, effectively blending immiscible oil and water phases. The macadamia oil component inherently delivers antioxidants, such as Vitamin E, which can support the skin's defense against premature aging and wrinkle formation.
