Ceramides are major lipid components in the stratum corneum of the human skin. Ceramide 3 consists of a phytosphingosine backbone N-acylated with a saturated fatty acid (stearic acid). It is widely used as a moisturizer in various cosmetic and personal products. Together with ceramide 1, they synergistically improve the skin barrier function in humans."}]
