Sixty healthy subjects aged between 18 and 50 will be randomly allocated into three treatment groups: Conventional Cryolipolysis, Contrast Cryolipolysis or Recovery Reperfusion Cryolipolysis. The region will be treated according to the individual need, in the region of abdomen and flanks. Assessments of body composition will be performed at baseline and 30, 60 and 90 days after randomization. Blood collections will also be performed at baseline and between 14 and 21 days after randomization for evaluation of lipid profile and liver function.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Conventional Cryolipolysis | Active Comparator | Subjects will receive one treatment session of conventional cryolipolisys. Subcutaneous fat tissue will be cooled with the cryolipolitic device for 60 minutes. The treatmente area will be the abdomen and/or flanks according to each patient's needs (pragmatic treatment). |
|
| Contrast Cryolipolysis | Active Comparator | Subjects will receive one treatment session of contrast cryolipolisys. Subcutaneous fat tissue will be heated for 10 minutes, cooled for 60 minutes, and heated again for 10 minutes with the cryolipolitic device. The treatmente area will be the abdomen and/or flanks according to each patient's needs (pragmatic treatment). |
|
| Reperfusion Cryolipolysis | Active Comparator | Subjects will receive one treatment session of Reperfusion Cryolipolysis. Subcutaneous fat tissue will be cooled with the cryolipolitic device for 60 minutes and heated for 10 minutes. The treatmente area will be the abdomen and/or flanks according to each patient's needs (pragmatic treatment). |
