At 8 months, most of the BBL result is usually close to stable, although small changes can still occur. In the photo, the buttock projection looks limited and the outer hip-dip area is still visible, but one back-view photo cannot show how much fat survived, how much was transferred, or whether your anatomy limited the change. The most common reasons are normal fat resorption, not enough safe donor fat placed in the lateral hip area, scar tissue, or a starting shape where the pelvis and muscle anatomy create a natural dip. At 5 ft 1 and 127 kg, safety is the first issue before any revision; many surgeons would recommend weight stabilization and medical optimization before another BBL or liposuction. An in-person exam with your original surgeon or a board-certified plastic surgeon can determine whether revision fat transfer, contouring, or weight loss first is the safest plan.
