Thank you for your question. There's no simple answer to your question. It could be very simple, done under local anesthesia, like neck or submental liposuction or could be quite complex like VASER Hi Def Lipo body sculpting (chest, abdominal etching, back, waist, hips, +/- fat transfer), done under intravenous sedation. So, it can cover your scale from 1 to 5. There are two kinds of liposuction: 1. fat reduction and 2. revealing. The first one probably falls in the 1-2 scale, the later is a technically challenging and artistic operation, scale of 5. Even though small hidden incisions are made to extract and/or re-inject the fat, wide areas are undermined under the skin and depending on the complexity of the surgery, there's extended swelling and recovery. The most important caveat is to choose the right board certified plastic surgeon experienced in advanced body sculpting techniques. Liposuction can have major complications in the wrong hands and poorly trained surgeon (poor results, perforation of internal organs and even death). Hope this helps.
