Does Thick Scar Tissue on Neck After Platysmaplasty and Submental Lipectomy Go Away on It's Own?

I am 2.5 weeks post-op on a platysmaplasty with submental lipectomy. The first 1.5 weeks everything looked great! At that point, very thick, unsightly scar tissue began to form on my neck right under my chin. It has gotten worse this past week, with puckering and raised indented areas. I have been told this kind of tissue can go away completely on its own. Can it? And what timeline am I looking at, in general? A month? Two years? I feel deformed and severely depressed because of these results.
