Ceramide Iii
What is Ceramide Iii?
Ceramide III is a sphingolipid molecule mirroring those in the human skin's stratum corneum, composed of a phytosphingosine base esterified with stearic acid. This structure makes it a key barrier lipid. In cosmetics, it serves as a skin conditioning agent-emollient, commonly found in moisturizers, creams, and serums. It works by embedding into the intercellular lipid matrix between skin cells, helping to restore and fortify the protective barrier. This action supports the skin's ability to lock in moisture and shield against external irritants. Often produced synthetically or from yeast for purity, it integrates seamlessly without altering skin texture. Its role enhances product formulations aimed at daily hydration maintenance, particularly in leave-on products where barrier support is essential.
