8 weeks post chin lipo I have some wavy skin under chin. Am I very close to the final result? (Photo)

I understand your concerns, but the fact that you still notice the stiffness and numbness should speak to the fact that you still have some swelling and healing going on.  That said, I would recommend some warm compresses, perhaps long hot showers, and gentle massage over the area for now.  I have seen this kind of thing take up to 4 months to resolve.Good Luck!

This could resolve over time and your skin may shrink. Follow up with your plastic surgeon as recommended to optimal results. 

 Did you have liposuction assisted by a laser or ultrasound? If this is the case the contour irregularities can last for a long time due to thermal damage to the skin and subcutaneous connective tissue.

This is what might be expected after defatting the neck where we cannot expect good skin retraction regardless of the process used. If you are satisfied at this point ultrasound and massage will help to redistribute some of the excess skin if you are unprepared to redrape the skin as would be accomplished with a lifting procedure

I generally tell people to expect results to be final by six months and very close to final by three months.The neck heals faster, so I would say your results are probably very close to being final.If someone has skin laxity before liposuction, it is sometimes accentuated a bit.Overall, it looks great.I'm pleased you are happy with the results.  The numbness will improve. That part of the healing process can take many more months but almost always comes back to normal after liposuction.Best of luck,Mats Hagstrom, M.D.
