  • BIODEGRADABLE POLYMER FINE PARTICLE FOR FILLER, FREEZE-DRIED BODY INCLUDING THE SAME, MANUFACTURING METHOD THEREOF, AND FILLER INJECTION INCLUDING FREEZE-DRIED BODY
    Publication number: 20240157025
    Abstract: Disclosed herein are a biodegradable polymer microparticle for a filler, a freeze-dried body including the same, a manufacturing method thereof, and filler injection including the freeze-dried body. The freeze-dried body includes hydrophilic surface-treated biodegradable polymer microparticle and a biocompatible carrier, wherein the hydrophilic surface-treated biodegradable polymer microparticle has an average particle diameter (D50) of 20 to 50 ?m and is polydioxanone which has a carboxyl group on the surface thereof. The hydrophilic surface-treated biodegradable polymer microparticle is a plasma surface-treated product or a base surface-treated product using discharge of the biodegradable polymer microparticle. The content of the biocompatible carrier is 1 to 5 parts by weight based on 100 parts by weight of the freeze-dried body.
