Bruising can persist for up to 2 weeks after Juvederm. If the discoloration itself is spreading a lot, or darkening in color (turning very black), or if you get spreading bumps on your lips or face (not herpes but something else), or if you have significant pain and throbbing, then you need to return to your injector immediately as you could have arterial blockage. It's really hard in the photo to tell if this is normal bruising (which I think and hope it is!), or possible blockage, but the fact that you are saying it's spreading onto surrounding skin is why I'm concerned a bit and stressing this point.
