I just had a BBL 3 weeks ago. How long should I wait for a round 2; wish I had gone bigger (Lost butt size). (Photo)

You have to consider not only which areas will have perhaps the best fat, but also you have to consider which donor sites will have the fewest problems afterward with the liposuction.  In general, the abdomen and thighs are preferred. Wait six months for round two as the resolution of swelling over the liposuctioned areas may take that period of time.Kenneth Hughes, Board Certified Plastic SurgeonLos Angeles, CA

Hi. You should wait at least a year to let the tissue heal and get integrated to the receptor site. It is too soon to see final results.

Typically, after a body contouring procedure, 50% of the swelling resolves after three weeks and 80% of the swelling resolves after six weeks.  The remainder of the swelling dissipates in the following three to six months.  Fat harvested from the thighs and/or arms can be used to contour the buttock.  

Hello,Thank you for sharing the information, it is a pleasure for me to answer your question.  you should wait for the recovery, it is very recent, it is advisable, wait 6 to 8 months after the procedure, the total recovery of the procedure takes from 6 months to a year, it is advisable to wait 6 months between each surgery, to avoid risks, your surgery is very recent, have a lot of patience
I hope this answer will help youMy best wishes for you ...
