i had .5 ml of Juvederm Ultra xc injected out 6 days ago. I just noticed that when I rub my lips together I can see a line that pops out, on top of my upper lip. Is this something I should be worried about? The filler looks great and feels fine, but on the side with the line that pops out, it does feel a lot more firm. I have had zero pain with he injections, and zero bruising. Everything has been perfect I'm just concerned about this weird line.
