| titleOfInvention | A kind of mixed gel for injection and its preparation method and application |
| abstract | The invention provides a mixed gel for injection and its preparation method and application, the mixed gel for injection comprises a gel matrix and polyhydroxyalkanoate microspheres, and the molecular weight of the polyhydroxyalkanoate microspheres is 50000 ~500,000 Daltons, the average particle size is 30-50 microns, and the mass fraction in the mixed gel is 15-30%. The present invention mixes PHA microspheres with specific molecular weight and average particle size with the gel matrix to form a mixed gel with good filling effect, maintain mechanical properties during the degradation process, and stimulate collagen hyperplasia after being injected into the dermis of the skin , activate the skin, effectively and gradually smooth wrinkles, realize the remodeling of the skin contour, and achieve the effect of long-term filling. In addition, its degradation product 3-hydroxybutyric acid is the natural energy source of human cells, which can promote the growth of fibroblasts and collagen Regenerates for a more visible cosmetic filling effect. |
