Due to its weak antigenicity and its good biological compatibility, the collagen is widely used in medical care fields, such as burning, injury or wound, cornea diseases, make-ups, firm tissue repair, wound surface hemostasia and so on. Our company selected the fish skin from the Tilapia mossambic as the raw materials for the collagen which is produced by the application of modern biological enzymolysis technology.
