摘要：
The present invention relates to a method for manufacturing polydioxanone particles (PDO) for a filler, more particularly to a method for manufacturing polydioxanone particles, which includes a step of mixing a solution of polydioxanone dissolved in a perfluoroalcohol with a polymer emulsion containing a polyethylene oxide-polypropylene oxide-polyethylene oxide terpolymer at a predetermined ratio to generate polydioxanone particles and then recovering the polydioxanone particles through aging and washing. The polydioxanone particles manufactured by the manufacturing method of the present invention can be favorably used as an injection for regenerating skin tissues.
