“Ceramides are very stable and considered to be a skin-identical ingredient. So, in addition to working effectively on human skin, they also work well alongside fellow skin-identical ingredients. These include vitamin E, niacinamide, lecithin and some plant oils (macadamia, sweet almond and olive in particular). Ceramides also work well with amino acids, peptides, glycerine, carrageenan, and hyaluronic acid.”
