Science
Mechanism of Action
This tetraester compound functions by forming a protective, non-aqueous barrier on the skin, effectively filling microscopic voids in the stratum corneum. This occlusive layer shields the skin from external environmental factors and significantly reduces trans-epidermal water loss (TEWL), leading to improved skin hydration and a softer texture. Additionally, it serves as a viscosity-increasing agent in non-aqueous formulations and can function as a binder.
