I received lip fillers for the first time in Dec 2021. I only received 1 cc. I went in to do another 1 cc in Mid-March. I’ve had a brown line on my upper lip. I’m not sure for how long it could’ve been before I got the procedure. Does this look like filler migration or melasma? What should I do? I would like another round of filler, but if it’s migrated I should dissolve first.
