Science

Mechanism of Action

This ingredient functions as an emollient by lubricating and conditioning the skin's surface, resulting in a softer and smoother appearance. It effectively forms a thin, waterproof occlusive layer, preventing transepidermal water loss and thus maintaining optimal skin hydration. Furthermore, Isodecyl Palmitate enhances product aesthetics by reducing greasiness and stabilizing emulsion systems.
