Three weeks is early healing
You had obvious skin laxity before surgery. This will improve partially with lipo, but you will still have loose skin. Only surgery can reduce that. Removing fat certainly improves definition, but a final result still needs time to evolve. This takes a few months.
Keep up with the really tight compression to decrease edema and encourage the skin the reapproximate correctly. You will likely continue to get some improvement in the laxity, but it will probably not completely resolve.
VASER Hi Definition Liposuction / Body Contouring with Fat Grafting and Tummy Tuck
you will have loose skin unfortunately you didnt chose the best procedure for your body type. you need a hi definition procedure to define and sculpt your musculature but the skin on your lower stomach has to go to get a tight and flat look. smartlipo (and I have it along with another laser for liposuction made by alma) is NOT effective in sculpting and defining and cannot tighten that much lose skin. you should really see a VASER HI DEF body sculpting 4D contouring expert. Post treatment you should be getting lymphatic massage, RF treatments and be on strict double compression -- thats my opinion. Best, Dr. Emer.
