Ceramides are lipids (fat) which holds the barrier together to help prevent moisture loss and protect skin from the external environment. A compromised barrier system is one which does not contain as many ceramides, cholesterol, and free fatty acids as compared to a healthy one. This then leads to skin dehydration, roughness, wrinkles, sensitivity, and makes skin more prone to irritation.
