Is this migrated lip filler? Is it possible to only dissolve the part above the lip? (Photo)

How bad is my filler mustache and would you say it looks unnatural? I had fillers done 3 times in total, each time 0.5 ml with 6 months and then a year in between. I never had small lips to begin with so I thought that with conservative amounts the issue of migration wouldn't come up. Is this due to poor injection technique? Is it possible to fix this in one appointment and make it look decent? I have an event coming up soon, so no time to dissolve everything and start anew at the moment.
