I had 0.5ml lip filler in mid October. I wanted them to look more hydrated, nothing else.Everything was perfect, minimal swelling, bruising and pain. However, almost 5 weeks after I got filler, I woke up with a strange crease on my left side. At first, I thought this was from a weird sleeping position, however, a week later and it's still here. What could this be? If it migrated, should I get them dissolved or could it subside on its own?
