Document Type and Number:
WIPO Patent Application WO/2022/048028
Kind Code:
A1
Abstract:
An electret facial mask for promoting absorption of phytoestrogen, and a production method therefor, relating to the technical field of cosmetics. The electret facial mask comprises an electret layer and a facial mask drug layer; an electret is obtained by polarization of a polymer material; the facial mask drug layer is a sheet layer, which is formed by a facial mask drug or a basic layer sufficiently absorbing the facial mask drug; the electret layer and the facial mask drug layer are packaged separately and individually; the electret is an electret after a sharp charge decay period. Before the electret facial mask is used, the electret layer and the facial mask drug layer are packaged separately and individually; when the electret facial mask is used, the facial mask drug layer is put on the skin first; then, the electret layer is put on the facial mask drug layer; the time during which the electret layer is attached to the facial mask drug layer is more than 30 minutes; the electret is used as a physical penetration promoting source, can supply a driving force for penetration of facial mask drug molecules, also can adjust a skin micro-structure, and can enhance absorption of facial mask drug molecules by skin tissue.
