At a low BMI, a bumpy abdominal contour is often less about needing major fat removal and more about the combination of skin quality, mild looseness, tethering or scar-like bands, small fat pockets, and the abdominal wall underneath. In the photo, there appears to be mild lower-abdominal skin laxity and creasing with uneven contour around the central abdomen, but an exam is needed to tell whether the skin, fat layer, or muscle separation is the main driver. If the skin is loose or there is diastasis, a mini or full tummy tuck may be the most reliable option, depending on the amount of extra skin and belly button position. If the skin tone is good and the issue is small fat pockets, limited liposuction can help, but it can make texture worse if the skin is already loose. Energy-based tightening may give modest improvement only. A board-certified plastic surgeon should check skin pinch, abdominal wall strength, and whether you have diastasis before choosing between liposuction, skin tightening, mini tummy tuck, or full tummy tuck.
