Is 'filler fatigue' real? I am interested in getting under eye fillers.

I am worried about the notion of 'filler fatigue', i.e. the stretching of the skin and fat pockets over time, leading to facial drooping and requirement for more filler in future. Some sources deny that this even happens and some claim that it does. What is the evidence? What is your personal experience? Also, does the bluish tint inevitably happen? I would be getting under eye fillers ONLY, I do not want to go down a slipperly slope and look unnatural.
