If this is fat, should I seek a revision from my surgeon? 8 weeks post (photo)

I got neck/chin liposuction 8 weeks ago. It definitely looks better but I still have a prominent roll of what appears to be fat/skin that becomes very visible when I bring my chin closer to my chest. I know that healing takes time and the skin/muscle needs to tighten back up, but could ALL of this really just be skin/muscle? I am in my twenties and seemed to have been a pretty good candidate. If this is fat, should I seek a revision from my surgeon?
