How do microbladed eyebrows look years later?

I want to get my eyebrows microbladed and have made appointments and cancelled. I am drawn to the fact that it is semi permanent. I have Botox and juvederm which appeal to me because they are temporary and it's a small commitment. However, I'm curious how the microblading looks when faded. Is it semi permanent in the sense that it will look blurry and pale and I will be forced to redo it. Or does it fade away completely with time? I can't find pictures of anyone that has had it for a long time.
