Does this result fall below the level expected for liposuction?

Thank you for your questions. It does appear that you have a moderate amount of skin laxity following your liposuction/fat harvest. Skin does contract back a great deal the first 6-8 weeks following 'debulking.' If you are within that time frame, I would recommend wearing compression to the abdomen until you are 6-8 weeks post surgery. It is very likely that you will need a tummy tuck to remove the excess skin.

The result fall is substandard not because of how the liposuction was done, but because you were not a good candidate for liposuction without a tummy tuck. Find a qualified surgeon in your area. UK? (We don't weigh people in stones in the US., even though your tag says California.)
