Ceramides are 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.
Eucerin uses synthetic Ceramides that are biologically-identical and that enhance skin’s natural barrier – locking in moisture and preventing dryness and irritation.
