Vascular compromise after filler injection is a major, emergent complication causing an embolism or compression that impedes blood flow.1 Although skin necrosis is most often associated with intravascular injection of the filler, external compression of vessels by the product is also proposed as a possible mechanism of injury. Local edema of adjacent vasculature secondary to the hydrophilic properties of the product can promote skin necrosis.
