The most serious risk associated with dermal fillers is the potential for accidental injection into a blood vessel. If this happens, it can cause skin necrosis (tissue death), stroke, or even blindness. Fortunately, when placed in the right places, the filler does not usually enter the blood supply. Instead, it is slowly reabsorbed by the body.
However, there have been cases where a filler was inadvertently injected into a blood vessel, resulting in catastrophic injuries to the face, eyes, and brain. To avoid this, it is always best to have dermal fillers administered by an expert in facial anatomy, such as a facial plastic surgeon. In the cases investigated, the injected material was well distributed in the lip tissue and there was no embolism or thrombosis. The location and position of the fillers were confirmed by ultrasound at the anatomically expected points. Part of the injected material was deposited in the deep part (pars peripheralis) of the OOM.
The injected material escaped up to 1 mm from the arteries and veins of the lips. Serious complications associated with fillers are often vascular, such as occlusions, which can cause necrosis (tissue death), scarring and, most importantly, blindness. While this is an extremely rare complication, there is a very real risk of blindness if a filling is accidentally injected into an artery or if the artery is compressed with the surrounding filling. Recently, a woman in Australia lost sight in one eye after receiving face injections in a beauty salon. Blood can't reach the eye because the filling obstructs the blood vessel, says Dr. Jasmine Mohadjer, an oculoplastic surgeon in Largo, Florida. Other available dermal fillers are those made with calcium hydroxyapatite, poly-L-lactic acid, polymethylmethacrylate and autologous fat (fat that is transplanted from another part of the body).
Dermal fillers can be composed of a variety of substances, some of which are natural and others synthetic. So what should smart consumers interested in non-invasive treatments to reduce signs of aging do? Finding the right doctor to perform the dermal filler procedure is key. This filler differs from other fillers because its results are gradual; volumization occurs over several months since it stimulates the body to produce collagen. When fillers are injected by a highly trained and experienced doctor, the risk of injecting a filler that ends up in the bloodstream would be incredibly remote. Therefore, it is important to do your research and find a qualified doctor who has experience with dermal fillers.
