Itching in the area treated with Cool sculpting is a common adverse reaction. It helps to ice the area or take oral Benadryl. If the itching continues for more than a week, you should contact your doctor. Cool sculpting is FDA approved and will not harm your liver. Coolsculpting is an excellent form of non-invasive fat reduction for the right patient. Some applicators take 1 or 2 hours but the new advantage applicators take only 35 minutes and have significantly less risk for delayed onset pain (especially in the abdomen). Results are seen at 2 months and typically 1-3 treatments will be necessary on each area to achieve ideal results. The number of treatments depends on the amount of fat there and the patient's goals. There is not downtime and the results can be impressive in the right patient. We also use the Zimmer Z-wave for improved patient comfort and added results. The best candidates are those who are in pretty good shape with areas of stubborn fat that won't go away no matter what.My best, Sheila Nazarian, MD, MMM Beverly Hills, Board Certified Plastic Surgeon
