Abdominal etching leaves swelling, bruising and numbness across the treated wall for several weeks, and a compression garment must be worn as instructed. Because fat is taken selectively along the muscle grooves, visible unevenness, firm areas, or grooves that read as too deep are recognised outcomes, and skin that retracts poorly may stay loose. Fluid collection, bleeding and infection are uncommon. For the buttock transfer, part of the grafted fat is absorbed and projection may reduce, while oil cysts, hard lumps, calcification or asymmetry can develop at the recipient site. Fat entering a vein during injection is rare but serious, which is why placement is kept out of the deep muscle. Sitting is limited during early healing.
