Ceramides are a type of lipid, or fat molecule, that are essential for maintaining the skin's barrier function. They help retain moisture and protect the skin from environmental damage, making them crucial for overall skin health. Ceramides are naturally found in the outer layer of the skin and contribute to its structure and hydration. In skincare products, such as lotions and creams, ceramides are often included to help restore the skin's natural barrier. They can be particularly beneficial for individuals with dry or sensitive skin, as they aid in reducing irritation and improving skin texture. Regular use of ceramide-infused products can lead to healthier, more resilient skin.
