Abstract:
Aesthetic injection has become an important treatment item of plastic surgery. Botulinum toxin and dermal fillers are the two major plates of injections. It is clear that the target tissue of botulinum toxin is expression muscles, whereas there are many filling materials to choose from. According to the mechanism, filling materials can be divided into three categories: volume fillers, collagen stimulators, nutritional glossers. The selection of these materials is related to the tissue type of the injection site. This article subdivides facial soft tissues into 5 horizontal layers: skin, subcutaneous fat, superficial muscular aponeurotic system, deep tissue, periosteum or deep fascia, as well as the the vertical ligaments, which compose a three-dimensional structure. The characteristics of these tissue structures are analyzed for selection of filling materials. Particular attention should be paid to the differences between volumetric fillers and collagen stimulators, which have completely different mechanisms of action, indications, and injection technique, with the former being suitable for deep tissues that require volume supplementation, and the latter for all types of tissues that require collagen supplementation. In conclusion, there is a close logical relationship between the choice of injection material and the facial anatomy.
