I heard more than once (although can't tell how trustworthy those sources are) that certain people experience the migration of their filler, so it ends ups somewhere where it was not supposed to go.
Does that happen often?
If so, does that happen with specific types of fillers? (permanent? semi permanent? never with temporary ones?)
And what is what causes, IF it happens, the filler to migrate?
When one is injected with any filler, for how long must the person not rub the area or what measures must be taken or avoided to impede or prevent that migration from happening? (in case it really happens)!
