Does microblading fade COMPLETELY over time? I had microblading Dec 2017. (Photos)

Before getting them done I was very sure that I wanted to do them. After I got them done they were extremely dark and thick. Although they have faded, I still see them a bit thick. To this point I have chosen not to do a touch up and I just want them GONE!!!! If I do not do a touch up will they fade COMPLETELY or will I see them more like a shadow? Is there anything that I can do to make them fade faster? PLEASE HELP!!!
