Easiest way to reduce prominent/padded chin? (Photo)

You have a horizontally projecting chin with an upturned soft tissue chin pad and, as a result, a deep labiomental fold. (which you refer to as a divot) int addition your chin is square shaped from the front view. A good treatment option is to vertically lengthen the chin bone which will pull down on the soft tissue chin pad and make the labiomental fold look less deep as well as reduce the horizontal projection of the chin. This will also desquare the chin a bit as well. That is a good option IF a longer chin appearance is acceptable to you. Computer imaging will help you make that decision.

your facial growth pattern is 'low angle' meaning a reduced 'slope' to the jawline. This yield a more horizontally projecting chin. You can have a genioplasty to increase the height slightly and reduce the prominence; and consider tapering the width of the chin from square to a more narrow contour.
