Gradient degradation injection gel easy to push and preparation method thereof

The invention provides an easy-to-push gradient degradation injection gel and a preparation method thereof, and relates to the technical field of medical beauty products. According to the injection gel easy to push and inject and capable of achieving gradient degradation, raw materials of the injection gel comprise bi-normal distribution degradation microspheres and a carrier, and the bi-normal distribution degradation microspheres are composed of microspheres with the particle size being 10-150 microns and microspheres with the particle size being 0-10 microns. The prepared injection gel has the advantages that the injection thrust is reduced, the gel loading density is improved, and the problem of local accumulation of the microspheres is solved, meanwhile, the degradation speed in the small-particle-size microspheres is higher than that in the large-particle-size microspheres, the bi-normal distribution system enables an injection system to be degraded in vivo to form gradient, and the metabolic pressure c
