PROBLEM TO BE SOLVED: To provide a foamable skin care preparation which enables two effects of increase of skin blood flow rate and the rise of the moisture content of the stratum corneum of the skin to be achieved with higher order simultaneously.SOLUTION: A foamable skin care preparation includes a basic granule and a viscous composition and is a two-agent type foamable skin care preparation in which the basic granule and the viscous composition are mixed when used. The basic granule contains at least a carbonate, and the viscous composition contains at least an acid substance which causes foaming by reacting with the carbonate and a ganoderma lucidum extract.COPYRIGHT: (C)2014,JPO&INPIT【課題】皮膚血流量の増加及び角層水分量の上昇という2つの効果を高次で両立できる発泡性皮膚外用剤の提供。【解決手段】本発明の発泡性皮膚外用剤は、塩基性顆粒と粘性組成物とからなり、該塩基性顆粒と該粘性組成物とを使用時に混合する2剤型の発泡性皮膚外用剤であって、前記塩基性顆粒が、炭酸塩を少なくとも含有し、前記粘性組成物が、前記炭酸塩と反応して発泡を生じさせる酸性物質及びマンネンタケ抽出物を少なくとも含有する。【選択図】なし
