Title: Skin care film based on biofiber

Description:
FIELD OF THE INVENTION 
     The present invention is based on a skin care film based on biofiber for promoting skin-repairing, skin-moisturizing and skin-soothing. 
     BACKGROUND OF THE INVENTION 
     Traditionally, in addition to smear-like products, facial skin products have been gradually derived from the use of absorbable materials to impregnate functional ingredients to form mask products, while mask products can be generally classified into film-type mask, paste-type mask, gel-type mask, solid-type mask or emulsion-type mask. Recently, mask products are often expected to have various designs and functions with a basic effect of moisturizing, or whitening, or pull-up, or firming, or revitalizing, or deep cleaning, depending on clinical care needs. 
     The film-type mask has the advantages of being easy to carry and to use the mask product, and therefore the film-type mask is now often used as a portable and convenient way for daily facial beauty care or daily skin care. Conventional film-type masks generally comprise a film carrier and a composition that is adsorbed in the film carrier and used for skin care. The skin care composition is either a solution or gel state consisting of various functional compounds that have moisturizing, anti-oxidant, rejuvenating, lifting, firming and whitening effects for the face. 
     With the improvement of living standards, people&#39;s consumption demand and demand for cosmetics are also rising, skin care products have become an indispensable part of people&#39;s lives. A wide range of skin care products as a one-off beauty mask, set moisturizing, whitening, skin repairing in one multi-function products, due to the use of simple, easy to carry, consumer market is very broad. The conventional surface/eye/function pleural single substrate, normally carries only acting substance, rather than have an effect of improving the absorption rate of skin nutrients; and it is also inferior in transdermal skin surface, it tends to cause skin irritation, and may even lead to allergies, not suitable for long-term use. 
     Furthermore, it is widely used for post-operative maintenance, postoperative care, postoperative temperature adjustment, postoperative cooling, and other clinical demands. Furthermore, with the improvement of the level of people&#39; life, the demand for beauty, the concept of skin care and maintenance, not only focus on the face, but also focus on other parts of the body such as breast and nipple, and believe that skin care in the other parts is important. However, the current market for the target is very little. 
     In view of the above reasons, products that are in good condition for daily maintenance and clinical care that meet the needs of different parts of the body are of major importance. 
     SUMMARY OF THE INVENTION 
     The present invention is based on a skin care film based on biofiber for promoting skin-repairing, skin-moisturizing and skin-soothing, comprising 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 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, wherein 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. 
     Preferably, said functional particles comprise a mixture containing a plurality of centella  asiatica  extract type particles, a plurality of Irish moss extract type particles, and a plurality of aloe extract type particles. 
     Preferably, said functional particles have a good compatibility with said bacterial-cellulose-type film body. 
     Preferably, the bacterial-cellulose-type body has a thickness of 0.2 to 5 mm. 
     Preferably, the said functional particle storage layer has a thickness of 0.2 to 5 mm. 
     Preferably, the said functional particle has a particle diameter of 0.001 to 0.01 mm. 
     Preferably, the a bacterial-cellulose-type film body utilizes a material selected from the group consisting of non-woven fibers, wood pulp fibers, cotton fibers, silk fibers, collagen, chitin, polysaccharides, protein fiber, peptide fiber, bio-cellulose, acetic bio-cellulose, bacterial cellulose, sodium alginate, agar, natural fiber and its mixture. 
     Preferably, the said skin care film based on biofiber has a shape of a circle, a ring, a square, a ring with an inside hole of eye&#39;s profile, a ring with an inside hole of ear&#39;s profile, a ring with an inside hole of nose&#39;s profile, a ring with an inside hole of mouth&#39;s profile, a ring with an inside hole of a breast&#39;s profile, a ring with an inside hole of a nipper&#39;s profile, and a circle having a multiple of inside holes selected from a group of an eye&#39;s profile, an ear&#39;s profile, a nose&#39;s profile, a mouth&#39;s profile and their mixture.
