Eligibility
Inclusion criteria
* Male or female subjects \> 18 years of age. * Subject who has been assessed to receive multiple CoolSculpting treatments on the abdomen and flanks, defined as follows: 1. Lower Abdomen - One 60 minute cycle with CoolMax, 2.

Side Effects in Treatment Area
Clinical assessments of the skin at the treatment sites to be performed immediately post-treatment, and at the 12 week follow-up visit. Subjects will be evaluated for skin changes at the treatment sites. The scale used by clinicians for the assessments is 0 = absent, 1= minor, 2= moderate, 3= severe.
