Ceramide 3 (also called Ceramide NP) is a lipid naturally found in the skin's stratum corneum that helps restore and maintain the skin barrier and reduce transepidermal water loss. It is widely used in moisturizers and barrier-repair formulations to improve hydration and skin integrity.
| Reported effect | How often | Notes |
|---|---|---|
| Mild transient irritation or stinging | Rare | Usually related to the overall formulation rather than ceramide itself; typically resolves quickly. |
| Allergic contact dermatitis | Very rare | Isolated sensitivity reports; ceramides are well tolerated as they mimic endogenous skin lipids. |
| Redness or itching | Rare | More often attributable to other excipients or preservatives in the product. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
