Skin surface is covered with very thin lipid film called as skin surface lipids. Skin surface lipids are the mixture of sebum originated from sebaceous gland and epidermal lipids. Epidermal lipid is the minor component of skin surface lipids and occupies less than 5 % of skin surface lipids. However, the epidermal lipids, especially ceramide, play an important role in water barrier function of the skin.
