Anatomical Position of Hyaluronic Acid Gel Following Injection to the Infraorbital Hollows

Abstract

In most specimens, the location of a significant portion of hyaluronic acid gel following injection to the infraorbital hollows differed from the intended injection plane. Soft tissue structures including fat compartment septa and the orbicularis oculi muscle appear to influence the resting position of hyaluronic acid gel. Careful attention should be used to avoid overfilling the thin soft tissue layers of the medial infraorbital hollows or tear trough.
