Excess fluid is absorbed over time. The fluid is similar with body fluid and is safe. Be sure to wear your compression garmet as this will minimize the swelling and retention of fluid.
Fat transfer and then Ultherapy can be done to reverse it. But unluckily, it can not be perfect. You can have multiple fat transfers if you have enough fat to be harvested. Thanks,
Fat generally does not enter the blood stream during a liposuction procedure.. very very rarely we read about fat embolization , but this is more common when fat is reinjected.
