In traditional liposuction, general anesthesia is used. If you will undergo this method of liposuction, expect that you will be heavily sedated. There is a higher risk of blood loss and tissue damage in traditional lipo. You would need a prescribed pain medication to relieve post-surgical pain. The old way of doing liposuction also posts higher incidence of complications, such as blood clots, severe bruises, and loose or saggy skin, which may actually require another procedure to have them removed.
In laser liposuction, local anesthesia is used, meaning, you will only feel the numbness on the body part that will be worked on. There is minimal or absent blood loss and tissue damage, and you do not need prescribed painkillers to treat pain after laser liposuction. If you experience discomfort, over-the-counter analgesics will do. Incidence of complications are minimal, and the thermal properties of the laser tend to tighten and smoothen the skin so there is no need to worry about wrinkly skin after the procedure.
