The outermost layer of skin, the stratum corneum (SC), is composed of corneocytes and an intercellular lipid matrix. The matrix acts as the main barrier. In the SC, the longitudinal arrangement of the lipid molecules consists of long and short lamellar structures and the lateral arrangement consists of hexagonal and orthorhombic hydrocarbon‐chain packings. From the temperature dependence of SAXD/WAXD, we revealed that a long lamellar structure is formed by hexagonal hydrocarbon‐chain packing and a short lamellar structure by orthorhombic hydrocarbon‐chain packing.
