Ceramide NP (formerly ceramide 3) is a naturally occurring sphingolipid that helps restore and maintain the skin's lipid barrier, reducing transepidermal water loss and improving hydration. It is widely used in moisturizers and barrier-repair formulations.
| Reported effect | How often | Notes |
|---|---|---|
| Mild transient irritation or stinging | Rare | Usually related to other formula components rather than the ceramide itself. |
| Contact dermatitis / allergic reaction | Very rare | Isolated case-level reports; ceramides are generally considered well tolerated and non-sensitizing. |
| Clogged pores or breakouts | Rare | More associated with occlusive base ingredients than ceramide NP itself. |
