Zeltiq's CoolSculpting kills fat cells by freezing them. one to three treatments can reduce significant amounts of localized fat. It is not an alternative to diet and exercise and is not appropriate in someone who is significantly obese. This is an excellent treatment and has a high patient satisfaction rate. Exilis requires more than five treatments usually and appears to temporarily reduce the fat volume. It doesn't kill the cells but seems to liberate the triglycerides from the fat cells. More research needs to be done to see if the long term results are similar with both devices.
