Invited response on: autologous biological vitamin-C added (ABC) filler for facial volume restoration

Dear Sir, We would like to thank Pensato et al. for their valuable comments regarding our recent article entitled ‘‘Autologous Biological Vitamin-C-added (ABC) Filler for Facial Volume Restoration’’ [1]. We are pleased that this study raised such an interest in the scientific community to discuss a new biological filler. The subjects mentioned in our study consisted of individuals over the age of 18 years who had no relevant diseases and were free of any medication known to affect platelet functions, including acetylsalicylic acid and any other nonsteroidal anti-inflammatory drugs, during for 7 days before the application. In our recent study, total blood count including platelet count, leukocytes concentration and the platelet/leukocyte ratio was not checked from each patient before ABC filler procedure.
