Caprooyl Sphingosine description

Caprooyl sphingosine is a skin care ingredient created from a mixture of fatty acids (caproic acid and sphingosine). This ingredient works to replenish and restore a healthier-looking skin surface, creating a smooth, hydrated feel. As a component of naturally occurring ceramides in skin, caprooyl sphingosine is effective at stopping moisture loss within skin’s uppermost layers. In 2020, the Cosmetic Ingredient Review Expert Panel concluded that caprooyl sphingosine is safe in cosmetics in the practices of use and concentration described in their assessment. Their report looked at products containing between 0.00033-0.00065% (high concentrations of this ingredient aren’t necessary for efficacy).
