Earlier types of liposuction sometimes resulted in areas that looked lumpy due to large cannulas leaving hills and valleys of uneven fat distribution. If fat deposits are causing the lumpiness, CoolSculpting may resolve this issue for you, but you may need skin tightening as well. If severe, I sometimes repair lumpiness with tumescent liposculpture using tiny cannulas on the hills and do a fat transfer to the valleys. However, if your problem isn’t too bad, non-invasive techniques may work well. CoolSculpting uses cryolipolysis – a patented technique that freezes fat cells, causing them to die and be permanently eliminated from the body – without affecting surrounding tissue. This means that if a lumpy bulging portion of your thigh was treated with CoolSculpting, only the fat would be dissolved, allowing the area to look smoother. You may need more than one treatment, as CoolSculpting can only eliminate 30% of fat at a time. It may also be possible to reduce small bumps with the injectable Kybella. This is typically used for fat under the chin, but if the bumps on the leg are small, Kybella plus skin tightening with Thermage, Thermi 250 or Exilis may give you the desired results. Please consult a board-certified dermatologist who is skilled in body contouring and skin tightening to see what technology will best solve your problem.
