Ceramide NS (formerly Ceramide 2) 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 formulation components rather than the ceramide itself. |
Contact dermatitis / allergic reaction | Very rare | Ceramides are well tolerated; sensitization is uncommon. |
Comedogenicity (clogged pores) | Very rare | Generally considered non-comedogenic; depends on overall formula. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
