Glycosphingolipids specifically include the amino alcohol sphingosine and a carbohydrate (usually a sugar, such as glucose or galactose) in its structure. Glycosphingolipids are found within cell membranes. Glycosphingolipids play numerous roles within cells, including maintaining membrane stability, regulating immune response, and facilitating signal pathways. In short, they’re a critical component in successful cell operation. A type of glycosphingolipid known as glucosylceramide is a precursor for the ceramides found in the uppermost layers of our skin. Interestingly, ceramides that undergo certain cellular modifications can become glycosphingolipids. In cosmetics, glycosphingolipids are used primarily as moisturizing ingredients with a focus on protecting skin’s barrier. Use levels of glycosphingolipids in skin care range from 0.1–0.5% for generalize barrier support and 1–3% when the goal is more intense barrier repair focused on the action of glycosphingolipids rather than combining a lower amount of them with other barrier helpers.
