Non-invasive Fat Reduction
Conditions
Brief summary
This study aims to generate data that conveys participant's experiences such as their overall satisfaction with the CoolSculpting® treatment for their belly and love handles. By doing this, the study will provide insights for doctors to better inform participants about the expected outcomes.
Interventions
A treatment session is comprised of timed segments of cooling (treatment cycles) followed by 2 minutes of manual massage.

| Change From Baseline in Volume of Fat as Measured by 3 Dimensional (3D) Photography | Baseline to 8 Weeks post-Treatment 1 and 12 Weeks post-Final Treatment 2 | Change in the volume of fat was assessed by a 3D stereoscopic camera which was used to generate a 3D image of the body, allowing quantification of the abdomen and flank areas.
