Why does my neck/jaw look like this 9 months after SMAS facelift? What can be done to make it better? Is this common?

Thank you for your pictures, I am sorry to hear you are disappointment with your surgery.  It is typical to have tightness after SMAS facelift.  The muscle has been targeted therefore initially feeling tight until it becomes a little lax, therefore not looking so pulled.  The asymmetry again, is typical and normally subsides.  Please ensure that you didn't have asymmetry to start with.  If you are unhappy, please return to your surgeon as they should rectify.  All The Best 

Sorry
to hear about your disappointing SMAS facelift results. It is normal to have
some tightness after a lift procedure, and this tightness will generally subside
with time. The asymmetry will also usually even out with time. Judging from
your before and after photos you provided, it seems the pulled look around your
jaw should relax, as this is the natural tendency of the skin.  If you are still not happy with the look
around your jawline, I recommend you discuss this with your surgeon, as it is
his/her responsibility to make sure you are satisfied with your facelift
results, and may suggest non-surgical solutions for your concerns.

The photos are a bit blurry so it is hard to see exactly your concerns. You are best to be seen in person to be properly evaluated.
