I am nearly 3 months post - neck lift and have a "cleft" or dent under my chin. It's caused by the incision under the chin (which is indented), and the skin surrounding the incision (which is not indented and at a different level). In profile, it looks odd -- almost like I have a slight double chin. Will this smooth out over time? Can a filler like Juvederm be injected into the dent to smooth things out? Thanks for your feedback.
