Fortilai technology is a new technology developed after all soft tissue defect filling materials and cell therapy technologies, which has all the advantages of other materials and technologies, such as rapidity and safety, and can realize full-thickness physiological repair and thickening of skin.

The mechanism of Folilai technology is a new tissue engineering technology based on injectable keratin-cell scaffold for tissue engineering repair, subcutaneous soft tissue defect filling and induced activated fibroblasts tissue repair. Keratin has a unique spatial structure, which provides an effective guarantee for the growth, survival and repair of transplanted cells.

Furilai rejuvenates the skin and gives full play to the role of filling and physiological repair. Experiments show that keratin is used to fill the skin to increase the thickness of the skin in view of the subcutaneous deficiency of aging wrinkles or depressions. Using the interaction between keratin and cells in skin, the survival rate and secretion function of implanted cells are obviously improved in the three-dimensional scaffold structure of keratin, and the inhibition of cell contact is eliminated. Keratin, as an activator of cells, induces macrophages to release fibroblast growth factor in the process of degradation in vivo, and promotes fibroblasts to secrete a large number of extracellular matrix needed by skin, such as collagen, elastic fiber and hyaluronic acid. To replenish organizational capacity and repair the broken network structure. Through intradermal and subcutaneous self-repair, the skin is thickened three-dimensionally, all wrinkles, facial tissue defects and depressions are eliminated, and the skin is smoother, more delicate and firmer. The implanted keratin materials can be swallowed and degraded by phagocytes in vivo.
