PCL microspheres are an important area of interest in regenerative filler development because their role extends beyond the initial physical structure of a formulation. As the polymer gradually degrades, the surrounding tissue also changes. Understanding how these processes interact is essential when evaluating PCL as a biomedical material. PCL, or polycaprolactone, is a biodegradable aliphatic polyester. In certain injectable filler formulations, PCL microspheres contribute to the initial filling structure while providing a material interface with surrounding tissue. Their longer-term behavior depends on polymer characteristics, particle properties, formulation design, and the biological environment. For researchers and manufacturers working with regenerative fillers raw materials, one distinction is particularly important: material degradation and tissue remodeling are related processes, but they are not the same thing. What Happens After PCL Microspheres Are Implanted? PCL degradat...
