Ceramide NS (Ceramide 2/NG) is a naturally occurring sphingolipid that helps form 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 attributable to other formulation components rather than ceramide itself. |
Contact dermatitis / allergic reaction | Very rare | Ceramides are skin-identical lipids and have very low sensitizing potential. |
Comedogenicity / breakouts | Very rare | Generally considered non-comedogenic; clogging more often linked to vehicle ingredients. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
