ABSTRACT
As a form of art, medical aesthetic injection can be comparable with architecture or sculpture using both foreign substances and self-tissue. The basic techniques of injection are fundamentally to lay volume and build up shape; basic techniques can be modified or combined to meet different clinical and anatomical challenges. Some techniques below are introduced and commented on for completeness; the title of “advanced” means they have higher complexity in technique, not that they are superior or better in terms of safety or efficiency.
