Ceramide 2 (Ceramide NS) is a naturally occurring sphingolipid used in skincare to help restore and reinforce the skin's lipid barrier, reducing transepidermal water loss and improving hydration. It is generally well tolerated and biocompatible with the skin's own ceramides.
| Reported effect | How often | Notes |
|---|---|---|
Mild irritation or stinging | Rare | Usually related to other formulation components rather than the ceramide itself. |
Contact allergy or sensitization | Very rare | Isolated reports; ceramides have low allergenic potential. |
Transient redness | Rare | Typically minor and self-resolving. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
