It's Been Three Months Since my Chin Lipo, is This my Final Result? (photo)

You are getting close to seeing your final result at 3 months especially if the suppleness of your skin is similar to your preop state, but you are not there yet. I tell my patients it takes up to a year for final resolution of the healing process. A chin strap often hastens recovery after neck/submental chin liposuction. In my experience, the above rough time table is usually delayed in smokers, when multiple procedures are performed together and when resurfacing procedures are done at the same time as the lift. The same is true if complications occur such as infection, hematoma, skin loss or compromise, etc

Do not lose hope yet.  An improvement in your results will definitely continue for even 6-12 months after your surgery.  I agree with your doctor that, at 23, your skin elasticity  will solve your problem over time.

In the grand scheme of things, having a non-result is much better than have had too much fat removed.  Although the technical details of performing neck liposuction are very straight forward, one still has to have a sculptor's eye to know how much fat needs to be removed and from what areas the fat needs to be removed.  Some inexpereinced liposuction surgeons (and they are hard to discern from expereinced liposuction surgeons because all surgeons beat their chest and say how I am, er they are) sometimes are very concrete about what areas they are treating.  Your photos do suggest that a time bit of fat was removed just under the chin.  However, a chin liposuction is not really a chin liposuction.  It needs to be a chin, neck, lower face liposution to get a great result.  What one is doing is removing fat to define the jaw line.  This should start back just below the ear lobes and define the volume at the neck/jaw line to sculpt this separation.  I am not sure I can recommend going back to the original doc for more work.  Bear in mind that this type of surgery can be performed in an office setting very comfortably under local anesthesia with virtually no down time.  Many patients have the procedure on a thursday and by Monday, no one knows they just had surgery.
