The photos show a linear depression along the side of the abdomen/flank with some surrounding contour irregularity. Two years after laser or VASER liposuction, a persistent dent like this is usually related to uneven fat removal, scar tissue or tethering between the skin and deeper tissue, skin contraction, or a combination of these factors. At this stage, massage or waiting is unlikely to make a major change. The best correction depends on whether the area is truly hollow, tethered, or surrounded by excess fullness. Options may include careful scar release or subcision, small-volume fat grafting to the hollow area, very conservative smoothing liposuction around the edges, or a combination. An in-person exam is important because over-treating the surrounding fat can make the line more obvious. I would see a board-certified plastic surgeon with revision body-contouring experience and bring your before photos and operative details if available. If the area is painful, enlarging, firm, red, warm, or associated with swelling, it should be checked promptly.
