Ceramides are the most important lipids in the hydrolipid film (which protects the external layers of skin). Produced naturally in healthy skin, they strengthen the skin barrier, helping to prevent moisture loss due to evaporation and keeping out irritants that can cause inflammation and itching. When skin’s Ceramide levels fall, the skin barrier is impaired. Skin can start to lose water and become dry and irritated.
Ceramide NP is a synthetically-produced, biologically-identical molecule that helps repair and regenerate the skin’s natural barrier to lock in moisture and prevent dryness and irritation.
