Science
Mechanism of Action
Cholesteryl Isostearate operates by establishing a biomimetic lipid barrier on the skin's outermost layer, the stratum corneum. This barrier actively reduces transepidermal water loss, thereby maintaining skin hydration and improving its natural barrier function. Its emollient and conditioning qualities further contribute to a softened, smoother skin texture by enhancing moisture retention and epidermal flexibility. Additionally, it serves as an emulsion stabilizer, preventing ingredient separation in formulations.
