Ceramides in Healthy and Diseased Skin
By: Myeong Jun Choi and Howard I. Maibach
Ceramides are the main polar lipids of the SC intercellular lipids; they play an important role in skin barrier function and account for half of the SC lipids by weight. Nine subclasses of ceramides have been described in human SC; these differ from each other by the sphingoid base groups (sphingosine, phytoshpingosine, 6-hydroxysphingosine) and hydrocarbon chain length. Ceramide content and changes of composition are involved in agingand skin diseases such as atopic dermatitis (AD),5–7 psoriasis, contact dermatitis (CD) and irritant dermatitis.
