How "good" is my result after FaceTite and liposuction treatment?

Results from FaceTite can take up to 6 months to fully appreciate the effects of the treatment. You should see additional improvement over the coming months. Make sure that you followup with your provider and they take photos to be able to compare the before/after. 

Dear Haverim,
I am sorry about your disappointment. Unfortunately, it is hard to evaluate the result without before photos and an in-person evaluation. I do see a nice neck-chin angle but there is some extra skin. 
Fortunately, you still have a few months to go before seeing the final result. For peace of mind, you can consider what the result would have been without FaceTite. FaceTite has been shown to reduce up to 38% of skin surface area after 6 months.
Having said that, you're getting there, and it is very possible that have too much skin to achieve the result you desire without skin excision (i.e., a neck lift). I am sorry again that you are disappointed - be upfront with your plastic surgeon about it - but I imagine you are looking at perhaps the best result achievable with today's technology, short of a neck lift.
I hope this helps and you still look great,
