1) at first, We have to harvest fat tissue from your abdomianal or gluteal or any other sites. and then the fat tissues are injected to your wanted area.
Of course The brusing or swelling may rise but it tend to almost subside operation 2 weeks later.
Usually transplanted fat tissue is absorbed 40 %, so it is needed to booster remained fat tissuues.

2) Don't worry about fat shift.

3) Usaually 40% of fat tissues are absorbed so reinjection is needed.

4) Operation 1 month larer you may go out to work.
