Will Laser Treatment Such As Elixis Melt Poorly Placed Juvederm Plus and Smooth out Wrinkles Left from Hyalurindase?

Lasers will not melt or decrease the lifespan of fillers. Most lasers don't penetrate to deep into the skin that will affect any previous treatments. I suggest having more hyaluronidase injected with a reputable skilled physician 

Honestly, probably not. When fillers are placed they settle and bond under the skin. They don't move with lasers or melt once they have been set well. Time will take away what is left or you could try more hyaluronidase, though it seems like that left behind another set of issues.
