Product Infomation
Product Name PDLLA Porous Microspheres
Catalog Number POL-TE094
Physical Specs 20μm-50μm;100-200μm
Description PDLLA porous microspheres are widely used in medical applications, particularly in the field of cosmetic and reconstructive surgery. Through subcutaneous injection, PDLLA porous microspheres stimulate collagen regeneration and improve skin elasticity, achieving natural plumping and rejuvenation effects.
Application PDLLA porous microspheres are high-performance subcutaneous stimulatory fillers sharing similar properties to PLLA porous microspheres but exhibiting faster degradation rates both in vivo and in vitro. Overall, PDLLA porous microspheres demonstrate outstanding biocompatibility and biodegradability as a novel facial filler material, stimulating collagen regeneration during degradation. Currently, PDLLA porous microsphere-based medical aesthetic fillers are widely adopted in clinical practice.
