C4

[Music] c4 this is an interesting code most of the injectors they do not understand it properly because there is one entry point and there is a place where we distribute the volume but this is the only code where we inject into the midline in the soft tissue the entry point is at the level of the sedimental region and then we direct with the needle towards the soft tissue the chin fat bat now i have a question to you if c4 is a single code we don't have right side or left side what does c4 do let me know
