Thank you for your question. After a Brazilian Butt Lift (BBL) surgery, a compression garment, also known as a "faja," is typically recommended to help reduce swelling, promote healing, and maintain the shape of the newly contoured buttocks. The pressure from the faja can also help to reshape the buttocks by keeping the newly transferred fat in place as it heals. The use of a full faja, which covers the stomach, hips, and buttocks, is typically recommended for the first few days after the surgery. This is because the buttocks and the surrounding areas have undergone significant changes during the procedure, and the full faja provides the most support and compression to these areas. However, it's important to follow the specific postoperative instructions of the surgeon and the faja use can vary depending on the surgeon and the patient's recovery. The faja is not a shaping tool, but a post-operative support tool, the shape of the buttocks is ultimately determined by the amount and distribution of fat transferred and the surgeon's technique. However, the faja can help to keep the newly transferred fat in place as it heals and may also help to reduce swelling and promote healing. Therefore, it's important to follow the surgeon's specific postoperative instructions regarding the use of a faja.
