Pulsating bump where Juvederm was injected on inner lower lip. Doesn't hurt, should I be concerned about labial artery? (photos)

Thanks for your question. Even if filler is injected in or near the labial artery, the result will not be a pulsatile sensation. It does appear that you may have a lump of filler present, but this could be improved with time or with some hyaluronidase injections by your physician. Best of luck to you.

Thanks for your question. The two components here are the raised bump and the pulsation. Harmful effects to an artery from filler injection are either because of injection into the center of the vessel itself (intraarterial injection) or excessive pressure on the artery (effectively closing it) from filler surrounding the artery. In either case any harmful effects (i.e. tissue supplied by the blood vessel not receiving blood and subsequent necrosis, or tissue death) would have appeared long before now. You do not need to worry about this. 
With regards to the bump, that is likely caused by a small amount of extra filler in that specific area. I would expect this to go away over the next 9-12 months.
