Science
Mechanism of Action
This ingredient works by forming a lightweight, protective film on the skin's surface, which effectively traps moisture and reduces trans-epidermal water loss, thus improving hydration and reducing flaking. It helps to restore the skin's suppleness and smooth its appearance. Furthermore, as a solvent, it aids in dissolving other ingredients, while its emulsifying properties ensure homogeneous dispersion of oil and water phases in a product.
