Non-surgical Rhinoplasty Redness Nightmare! Allergic Reaction?

An allergic reaction to Juvederm is extremely rare. Redness can be caused by many factors.  Best to follow up with your doctor who can evaluate you in person.  This is really not the forum to answer your concerns without seeing you. Sorry

The concept of fixing small defects in the nose with filler sounds like a nice and easy solution.  However, there are risks associated with it.  It sounds like what has happened is the vascular supply of the nose has been compromised.  If not recognized early, you have potential for skin necrosis (loss).  Hyaluronidase, heat, massage, needs to be done in these cases.  I have stopped doing the "5 minute nose job" because of more and more reports of this happening.  The reason it happens is because the filler either goes into the vessels supplying the nose or compresses it.  This can happen anywhere on the face and is one of the reasons that blunt cannulas are safer.  Blunt cannulas can not enter a vessels so that eliminates the most common etiology of this problem.
