Recovery time after chin implant removal: when will I look like normal (i.e. pre-op) again? Should I use ice for swelling?

I had a chin implant for 4 weeks. Then it was removed and i have been without it for a week or so. My question is, is ir normal that i look like i still have the implant in? I really want to know how long should I wait till I look like pre-op. I'm really desperate. I want to know also if my skin will shrink back to normal. How does that happen? Should I use ice for swelling? Like I said I only had the implant for 4 weeks.
