Science
Mechanism of Action
This ingredient functions by supplying key lipid components and stimulating the skin's inherent ceramide production. Ceramides are critical lipids in the stratum corneum, forming a robust natural barrier against moisture loss and external aggressors. Glucosylceramide, a core component, directly contributes to a healthy skin barrier and enhanced hydration, while also upregulating intrinsic ceramide synthase-3 (CerS3) and glucosylceramide synthase (GCS) expression to boost overall ceramide synthesis and repair.
