Ceramide AP (ceramide 6-II) is a naturally occurring sphingolipid that helps restore and maintain the skin's barrier function and reduce transepidermal water loss. It is commonly used in moisturizers and barrier-repair formulations, often combined with other ceramides, cholesterol, and fatty acids.
| Reported effect | How often | Notes |
|---|---|---|
| Mild transient irritation or stinging | Rare | Usually related to the overall formulation rather than the ceramide itself. |
| Allergic contact dermatitis | Very rare | Isolated reports; ceramides are generally well tolerated and non-sensitizing. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
