Should I dissolve my filler? (Photo)

2 weeks ago I had .5 ml of a filler called lips injected. I've been to my provider (An RN who's been in peace's for 18 yrs) who said all looked fine. To me it looks as if it's migrated or shelved and I'm left with the appearance of a mustache from the shadow. Is this poor filling technique or am I just not the right candidate for lip filler? Should I get it dissolved? Even after 2 weeks I can still feel the filler and the occasional itching as well. Thanks for the help!
