Science

Mechanism of Action

This ingredient functions as a skin conditioning agent and emollient by closely mimicking natural sebum, which ensures outstanding compatibility with the skin's existing barrier. It actively forms a protective layer to lock in moisture, improving skin elasticity and resilience against environmental aggressors. Its unique structure provides a lightweight, readily absorbed texture, avoiding the heavy residue of traditional oils, and ensures an even distribution of nutrients, culminating in a luxuriously smooth and soft after-feel. Furthermore, it stabilizes formulations, guaranteeing product consistency and spreadability.
