PURPOSE: A microparitcle filler system which is easy to inject is provided to improve stability of initial injection skin and to uniformly inject microparticles. CONSTITUTION: An injection agent contains polymer particles, thermosensitive phase transition biocompatible polymer solution. The biocompatible polymer is polyethylene oxide(PEO)-polypropyleneoxide(PPO) copolymer, polyethyleneoxide(PEO)-polylactic acid(PLA) copolymer, polyethyleneoxie(PEO)-polyglycholic lactic acid(PLGA) copolymer, or polyethyleneoxide(PEO)-polycaprolactone(PCF) copolymer. The biocompatible polymer solution is alginic acid, hyaluronic acid, carboxymethyl cellulose, dextran, collagen, gelatin, or elastin. The injection is used for treating urinary incontinence or as a prosthetic filler for plastic surgery.
