Science

Mechanism of Action

This ingredient operates as an effective skin conditioning agent by softening and smoothing the epidermal surface, thereby enhancing skin texture and appearance. It forms a breathable, occlusive barrier to prevent transepidermal water loss, ensuring sustained hydration. Furthermore, it functions as a viscosity controlling agent, contributing to the desired consistency and stability of emulsions, and acts as an emollient to deeply nourish the skin.
