Ceramide 11 (also designated ceramide 5) is a lipid component naturally found in the skin's stratum corneum, used in skincare to help restore and maintain the epidermal barrier and reduce transepidermal water loss. It supports moisture retention and barrier integrity rather than acting as a chemically active treatment agent.
| Reported effect | How often | Notes |
|---|---|---|
Mild transient irritation or redness | Rare | Generally well tolerated; irritation more often linked to other formulation components than the ceramide itself. |
Contact allergy or sensitization | Very rare | Sensitization to ceramides is uncommon; reactions usually attributed to accompanying excipients or fragrances. |
Clogged pores / comedogenicity | Rare | Possible in occlusive lipid-rich formulations on acne-prone skin, though ceramides are considered low risk. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
