Comparison of the efficacies of polycaprolactone filler and lidocaine-added filler on neocollagenesis in a rat model.

Background: Polycaprolactone (PCL) is a semi-permanent filler stimulating neocollagenesis. Lidocaine is frequently used to reduce the pain and, however, may have negative effects on collagen. It was aimed to compare the histological changes on rat skin and efficacies of PCL filler and lidocaine addition.
