As with any medical procedure there are some risks to consider. Most patients will have some degree of swelling associated with this treatment, but this will settle over the following few days. There may be some discomfort, bleeding or bruising. There have been cases in Australia of vascular injury whereby filler is inadvertently injected into a blood vessel. It is very rare but if it occurred could lead to necrosis of the skin or visual loss. A thorough knowledge of facial anatomy and safe injecting techniques can greatly minimise this risk, however if any signs were to occur the filler would need to be dissolved immediately.
