Science
Mechanism of Action
This ingredient effectively reduces the surface tension between immiscible liquids, allowing for the creation and stabilization of uniform oil-in-water emulsions. On the skin, it forms a protective, occlusive film that significantly decreases transepidermal water loss (TEWL), thereby enhancing skin hydration and preventing dryness. Its emollient properties contribute to a smoother skin feel, while its mild surfactant capabilities can aid in gentle cleansing.
