Ceramide NG (formerly ceramide 2) is a synthetic skin-identical lipid that helps restore and reinforce the stratum corneum 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. |
Allergic contact dermatitis | Very rare | Ceramides are skin-identical and generally non-sensitizing; reactions are exceptionally uncommon. |
Acneiform breakouts / clogged pores | Rare | Possible in very occlusive formulations on acne-prone skin, not directly attributable to the ceramide. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
