The photos were reviewed and appear to show mild residual lower abdominal skin laxity and texture irregularity rather than an acute problem; a hands-on exam is needed to tell how much is loose skin, scar tethering, or small residual fat. Two years after a tummy tuck, this is not likely to change much on its own. Some degree of laxity can persist even after a well-done tummy tuck, especially if the original skin quality was poor, there was a lot of stretch damage, weight changed, or the remaining upper abdominal skin had limited elasticity. It may be common, but if it bothers you, it is reasonable to ask about revision options. Non-surgical tightening treatments such as radiofrequency, ultrasound, or microneedling with RF may give modest improvement for texture and very mild looseness, but they usually cannot remove a true fold of extra skin. If there is enough pinchable excess, a surgical revision, scar revision, or small additional skin excision is usually more predictable. If the issue is mainly contour or a small fat pocket, limited liposuction may be considered, but liposuction alone can make loose skin look worse. I would see your original surgeon or another board-certified plastic surgeon for an exam and a discussion of whether the skin can be revised safely without raising or distorting the scar.
