Ceramides are a type of lipid, or fat molecule, that are naturally found in the skin. They play a crucial role in maintaining the skin's barrier function, helping to retain moisture and protect against environmental irritants. By keeping the skin hydrated, ceramides contribute to a healthy and youthful appearance. In skincare products, ceramides are often included to enhance hydration and improve skin texture. They can be found in creams, lotions, and serums, making them popular ingredients for those with dry or sensitive skin. Regular use of ceramide-infused products can help restore the skin's natural barrier and promote overall skin health.
