Ceramide Ng

Ceramide NG is a skin-identical barrier lipid used at low concentrations (typically well under 1%) to replenish stratum corneum ceramides and reduce transepidermal water loss. In clinical and patch-test experience, ceramides themselves have very low irritancy and are generally well tolerated even in eczema-prone or post-procedure skin; reactions, when they occur, are more often attributable to the vehicle or accompanying surfactants/preservatives rather than the ceramide. Given its barrier-supportive role and minimal intrinsic irritation potential, it fits 'exceptionally gentle' rather than completely inert. Safety Notes: In mass-market moisturizers, cleansers, and lotions, Ceramide NG is commonly used as part of multi-ceramide blends at trace-to-low levels (often ~0.0001–0.05%) because of cost, solubility/dispersion constraints, and the ability to claim “ceramides” with very small additions. Higher-strength consumer barrier-repair creams/serums and concentrated ceramide complexes can reach ~0.3–1.0% Ceramide NG (typically leave-on; rinse-off products usually sit at the low end due to limited deposition), with levels above ~1% being uncommon in OTC due to formulation difficulty and diminishing practical benefit without specialized delivery systems.
