Abstract

Because both the liposome and bicell structure particles remain stable over the long term, this provides a highly emollient topical skin composition that combines barrier function and a penetrating feel. [Solution] A topical skin composition containing liposomes and a bicell structure, wherein the liposomes contain component (A) phospholipids, component (B) phytosterols, and component (C) polyhydric alcohols with an IOB value of 2.0 to 5.0, and the bicell structure contains at least one surfactant selected from the group consisting of component (D) phospholipids, component (E) ceramides, component (F) polyoxyethylene sterol ethers, polyoxyethylene stanol ethers, and polyglycerin fatty acid esters which are esters of polyglycerin with an average addition mole number of 5 to 20 and fatty acids having 10 to 22 carbon atoms, and component (G) a dihydric alcohol such as propylene glycol.
