In short
A C18:1 unsaturated ceramide that adds flexibility to the skin’s lipid layers. It supports comfortable hydration and complements more rigid saturated ceramides.
What it is
Mono-unsaturated C18:1 ceramide NP-type variant; the cis-oleoyl chain imparts greater fluidity to lipid bilayers than the saturated C18 stearoyl analogue; minor component of the native stratum corneum ceramide profile; incorporated into broad-spectrum ceramide complex formulations to provide unsaturated-chain coverage alongside the more abundant saturated ceramides.
