Ceramide 6 (Ceramide AP) is a naturally occurring lipid that helps restore and maintain the skin's barrier function and reduce transepidermal water loss. It is commonly included 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 other formulation components rather than ceramide itself. |
Contact allergy / sensitization | Very rare | Ceramides are well tolerated; allergic reactions are uncommon and poorly documented. |
Redness or localized reaction | Very rare | Typically associated with overall product rather than the ingredient alone. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
