Bad liposuction can cause lumps, dents, rippling, or uneven fat removal, leading to an unnatural appearance. Hard lumps or fibrosis may develop, causing discomfort or tightness. Asymmetry between treated areas or excess sagging skin can indicate poor technique. Skin discoloration, excessive scarring, or fluid buildup are also warning signs. If results look irregular or feel painful, consult a doctor for assessment. Treatments like massage, laser therapy, or revision surgery may help.
