Neck injection aesthetic, a commonly performed clinical procedure, is still lacking in comprehensive guidelines or consensus. This expert consensus is co-authored by experts from the Injection Aesthetics of the National Quality Control Center of Plastic and Aesthetic Surgery. It elaborates on formulation method of consensus, the relevant contents of neck aesthetics and anatomy, botulinum toxin injections, filler injections, collagen stimulator injections, autologous tissue components injections, and combined treatments of injections with electrophoto-therapy. The consensus incorporates relevant evidence-based medical references, as well as multiple discussions. Ultimately, a basic clinical operational expert consensus was formulated, with the aim of serving as a reference for clinical physicians in their practice.
