Ceramide AG (ceramide alpha-hydroxy fatty acid linked to a sphingosine base) is a lipid component that mimics naturally occurring skin ceramides, helping to restore and reinforce the skin barrier and reduce transepidermal water loss. It is commonly included in moisturizers and barrier-repair formulations.
| Reported effect | How often | Notes |
|---|---|---|
| Mild transient irritation or stinging | Rare | Generally well tolerated; irritation more often attributable to other formulation components. |
| Allergic contact dermatitis | Very rare | Isolated case reports; ceramides are considered low-sensitizing. |
| Clogged pores / comedogenicity | Rare | Possible in acne-prone individuals depending on overall vehicle, not the ceramide itself. |
