The patch type mask is widely selected by people due to its convenient use. The application type facial mask is more and more popular among consumers due to the remarkable efficacy. However, most consumer skin problems are complex, and different parts of the face have different skin care requirements, so the skin problems which the consumers want to solve by the facial mask are also complex rather than single, for example, the cheek requirements are acne removal and allergy relief, and the T-zone requirements are skin brightening, pore astringing, water replenishing and the like. The efficacy of the patch mask depends on the uniform distribution of the mask liquid on the mask cloth, and the fine care of skin cannot be realized. Although traditional formula facial mask of paining can scribble different efficiency nature products by subregion, there is more inconvenience during the use, if want the regional even application of scribbling and need spend more time energy with the help of the instrument, if mishandling can lead to different products to mix and can not reach the effect of paining by subregion. Meanwhile, most of the smearing type facial masks are mud in texture, the smearing time is too long, and the product is easy to dry and not easy to clean; repeated cleaning and rubbing of the skin easily damages the skin surface layer, and easily causes skin sensitivity.
