One of the most important lipid categories that make up human sebum is ceramides. Ceramides are naturally able to fill in the gaps between the skin cells and are a critical component in keeping the skin strong & moisturized.
Over time, ceramide levels in the skin become depleted, leading to dryness and dehydration. This lack of moisture in the skin makes it look saggy and tired and emphasizes wrinkles. Low levels of ceramides can lead to a variety of inflammatory skin conditions, which lead to redness and irritation as well as long-term damage.
Look for ceramides in moisturizers to keep your skin soft & supple this winter.
