Ceramide NP, AP and EOP
Ceramide NP, AP and EOP — specific types of ceramides, the lipid molecules that help make up the skin's outer barrier, identified by a naming system that reflects their molecular structure. NP, AP, and EOP are among the ceramides commonly used in skincare to help support and replenish the barrier's natural lipid composition.
Key points
- Ceramides are naturally present in the skin barrier and help hold skin cells together while limiting water loss.
- The letters in names like NP, AP, and EOP refer to the specific fatty acid and base components that define each ceramide type.
- Formulas often combine several ceramide types to more closely mirror the mix found naturally in the skin.
- Ceramide NP is one of the most commonly used types in barrier-focused moisturizers and serums.
Frequently asked
What do the letters in ceramide NP, AP, and EOP mean?
The letters follow a standardized naming system indicating the type of sphingoid base and fatty acid that make up each ceramide. Different combinations correspond to the various ceramides found naturally in skin.
Why are multiple ceramide types used together?
Skin's barrier naturally contains a blend of ceramides, so combining types like NP, AP, and EOP aims to better reflect that composition. This is thought to support the barrier more comprehensively than a single type alone.
