Coolsculpting (Cryolipolysis) – Body Contouring, Slimming


  • Cryolipolysis (Coolsculpting) by Zeltiq is a safe, effective and non-invasive treatment to reduce unwanted fat bulges by cold treatment.
  • An applicator is applied to the targeted area causing cold injury to the fat cells. The injured fat cells are gradually resorbed and eliminated from your body over a period of 2-3 months.
  • This treatment reduces the fat bulges slimming the body contour.
  • The results are proven, noticeable, and long-lasting. Visible results can be seen from the first session.


  • The Cryolipolysis (Coolsculpting) applicator creates a vacuum to suck in the targeted fat bulge. Significant cooling occurs in the applicator chamber damaging the fat cells by crystallisation without affecting the surrounding tissue. This is because the fat cells are more easily damaged by cold temperature than the surrounding cells.
  • The damaged fats cells are removed by the body starting from 2-4 weeks after treatment. This process is complete by 2-3 months.

  • Dr Dieter Manstein, MD, PhD and R.Rox Anderson, MD of teaching affiliate of Harvard Medical School and their team discovered “selective cryolysis” in which selective fat reduction without affecting adjacent tissue can be achieve via prolonged controlled cooling / energy extraction of targeted fats.

During the consultation, Dr Ng would advise the best option for sculpting and slimming the body by Coolsculpting or liposuction. The top priority for the plastic surgeon is to plan the location and distribution of the Coolsculpting applicator on the treatment area for best outcome.
