Title:
INJECTABLE COMPOSITION FOR SKIN TISSUE REGENERATION OR SKIN TISSUE VOLUME INCREASE COMPRISING HOLLOW POROUS MICROSPHERES
Document Type and Number:
WIPO Patent Application WO/2017/065429
Kind Code:
A1
Abstract:
The present invention relates to an injectable composition for skin tissue regeneration or skin tissue volume increase comprising hollow porous microspheres comprising a cavity in the center thereof and a barrier surrounding the cavity and comprising fine pores. The hollow porous microspheres comprised in the composition according to the present invention have a small particle size, thus can be administered by an injection into skin tissue, and allow moving skin tissue cells to effectively proliferate within the cavities. After a predetermined period elapses, the newly proliferated skin tissue cells maintain the volume thereof even after the hollow porous microspheres biodegrade inside skin; thus, skin tissue regenerative effects can be safely maintained for a long time.
