Does filler migration reduce teeth show and elongate the philtrum?

Maybe a silly question—I know lip filler itself will naturally reduce teeth show but what about filler that has migrated to the philtrum ? I ask because I’m probably getting my filler dissolved and refilled, and I’m hoping it will shorten my philtrum back up so that you can see my teeth, but I’m scared my philtrum is just longer because I’m older now. I’m 30 for context
