Abstract

A skin care film based on bioliber for promoting skin-repairing, skin-moisturizing and skin-soothing, including a bacterial-cellulose-type film body having a first surface, a second surface, which is opposite to the first surface, a functional particle storage layer, disposed on said first surface and containing a plurality of functional particles, a plurality of functional particle channels disposed throughout said bacterial-cellulose-type body film body and connect the said first surface with said second surface; and a plurality of functional particle inside-channel control-released layer provided on inner surface of said functional particle channel, said functional particles having a size smaller than the inner diameter of the functional particle channel and said functional particle inside-channel control-released layer is structured in such a way to assist controlled release of said functional particles that diffuse across said functional particle channels from said functional particle storage layer to said second surface.
