Ceramide NP, Ceramide AP, Ceramide EOP, Phytosphingosine, Cholesterol

This ceramide complex combines three essential skin-identical ceramides (NP, AP, and EOP) with phytosphingosine and cholesterol in a biomimetic ratio that mirrors the natural lipid composition of healthy stratum corneum. The liposomal delivery system enhances penetration and bioavailability of these lipids, making it particularly effective for barrier repair in compromised or aging skin. Formulators choose this specific combination because it addresses the complete lipid profile needed for optimal barrier function, rather than relying on a single ceramide type, with the cholesterol and phytosphingosine acting synergistically to organize the lamellar bilayer structure.
