  In an era when regenerative medicine, aesthetic medicine, and efficacy-oriented skincare are increasingly converging, PCL raw materials are becoming an important area of focus in the field of polymer materials. Their significance lies not only in their biodegradability, but also in their ability to provide structural support, controlled release and delivery, and tissue repair, enabling them to serve as a “material foundation” across different applications. I. What Is PCL Raw Material? PCL is short for polycaprolactone, an artificially synthesized biodegradable polyester polymer material. From a molecular structural perspective, its repeating unit contains five non-polar methylene groups and one polar ester group. This structural characteristic gives PCL good flexibility and processability. Its typical characteristics include good biocompatibility, a semi-crystalline structure, and relatively slow degradation. Depending on the clinical application, when used as an aesthetic injec...
