Ceramide NG

Ceramide NG is one of the twelve ceramide classes naturally present in the human stratum corneum, built on a sphingosine backbone. It participates in the lamellar organisation of the barrier lipid matrix and is frequently included in modern ceramide complexes alongside NP, AP, and EOP. Research on ceramide-deficient skin — aged, atopic, or over-exfoliated — supports topical replenishment to reduce moisture loss and visible flaking. In formulations it appears at low concentrations (0.01–0.5%) within lipid-compatible bases. Best results come from consistent daily use in creams or serums that also supply cholesterol and fatty acids, mirroring the skin’s native 3:1:1-type lipid ratio.
