Thank you for your question. At my practice, I perform many BBL and tummy tuck combo procedures. However, if you're considering having a BBL and tummy tuck done individually, then it makes sense to do the tummy tuck first. Then 4-5 months later, a BBL can be performed. The reason being that if you have significant excess skin and you get liposuction in that area, the area will look wrinkled, scarred, and irregular. Also doing significant liposuction on the abdomen and then having a tummy tuck later can predispose you to wound healing complications after the tummy tuck. I would recommend getting a proper evaluation by a board certified plastic surgeon. Take care, Moises Salama MD, Board Certified Plastic Surgeon
