Getting a 3MM submalar Cheek Implant removed, how long does the scar capsule take to go away?

Im 20 years old, good skin laxity, and im unhappy with my cheek implants as they my face look round and puffy. Im gonna get them removed. I had them in for 6 months. People have said that even when you remove it there is still a scar capsule that makes it look like the implant is still there. How long will that take to go away and i look somewhat like I did preop?
