After filler injection in the nose can the filler migrate and block an artery weeks/months later causing skin loss or blindness?

Hi. Thank you for your question. High risk areas such as the nose are best injected with cannula to reduce vascular complications. The signs and symptoms of adverse reaction are either immediately noted or within 24-28 hours. Post injected filler will not migrate intravascularly.

Thank you for your question.  Filler should always be injected slowly and using a retrograde technique to reduce the risk of product entering a blood vessel.  Complications would be evident immediately and are quite rare.  My advice is to seek treatment with an experienced injector who understands risk and facial anatomy.  Best of luck.

Thank you for your question!  Filler when injected can enter blood vessels through the use of sharp needles or cannulae. If injected under high pressure and in large volumes it can block blood vessels and enter crticial vessels that can cause skin loss or blindness. Experienced injectors therefore inject slowly, constantly move their needles, and inject with blunt cannulae in higher risk sites. If a complication was to occur it would occur immediately, and there is no way for filler once placed outside the blood vessel to move intravascular of its own accord. Best of luck!
