There are risks with all medical and cosmetic procedures, especially with injections. There are risks to doing filler injections facially, particularly if the filler substance gets into the bloodstream accidentally. Wrongful placement of injections is usually more of a problem with untrained, inexperienced practitioners. A rare risk is a compromised blood supply when the filler gets into arteries that supply the nose or eyes. If filler gets into an artery, it can cause a blockage, which results in the affected tissue lacking needed blood supply.  Local blood supply integrity is of great importance, so having a well-trained practitioner is key. This undesirable situation can affect the nose and eyes, depending on which artery is affected. In Australia, there has been some cases of blindness from filler.  Previous nasal surgery can increase risks. .  Unexpected adverse reactions to the filler we use can happen, it’s not impossible to have a bad reaction to an injection.
