Ceramides are lipids (aka fat molecules) that are found in high concentrations within cell membranes. Lipid’s have one of three functions -- they make up part of the structure of a cell’s membrane, storing energy or signaling actions in cells. Ceramide is a structural and signaling molecule. It is made up of a fatty acid called sphingosine and is located within the membrane of cells, in great concentrations.
Like the gut, the skin has its own microbiome universe, a complex ecosystem of fungi, bacteria and archaea that serves as the foundation for healthy skin. Our skin's structure and function is absolutely essential to our general health. The skin microbiome, found at the surface of the skin, is your skin's first line of defense. The three elements of a healthy skin barrier are the skin microbiome, the acid mantle and the lipid barrier, which work in harmony to protect against irritants, environmental damage and infection.
