What are the signs of necrosis after lip fillers? Would my practitioner be able to tell straight away, if they're experienced?

Any injector should know the signs of a vascular occlusion. The first few signs would be blanching and immediate pain in the area. Luckily if treated in time, this is reversible and should not cause any permanent damage. If you are feeling uncomfortable or hesitant, I would make a consultation with your injector to address any concerns.

Dear anon37910,Thank you for your question. Due to the robust blood supply to the lip, necrosis is extremely rare. Pain, mottling, and duskiness could be signs of early necrosis. If the filler is reversed promptly by an experience injector, worse effects should not happen, such as black, full thickness necrosis and ulceration. Good luck,Nirmal R. Nathan, M.D.

 I appreciate your concern, however necrosis after injections with fillers is extremely rare. After years of experience with this procedure I have never seen it. However, an experienced injector can immediately identify early signs of this complication and minimize any problems by immediately injecting Hyaluronidase. Consult with a board-certified plastic surgeon or dermatologist for this procedure. Good luck.
