What is the main reason patients must avoid sitting directly on their buttocks after a BBL?

Answer

To ensure transferred fat cells establish a blood supply and survive

The survival of the newly transferred fat is highly dependent on its ability to integrate with the surrounding tissue and establish a new blood supply. If a patient sits directly on the area, the pressure can compromise this process, leading to a higher rate of fat cell death and potential fat necrosis. Patients are usually instructed to use special pillows that distribute weight onto the thighs instead of the buttocks to protect the integrity of the graft during the critical early recovery phase.
