Protruding chin? (Photos)

Even with a slight overbite, my chin juts out a bit when viewed from the side, especially when I smile. As you can see, there's a small fatty deposit that can be pinched and moved around. I know that there's only so much that can be determined from just a few photos as opposed to a real examination, but from what you can see, would removing or reducing that fat/extra skin change the profile of my chin significantly? Cost estimates would also be appreciated. Thank you!
