Bruising

The goal of this clinical trial is to evaluate if CO2 Lift reduces bruising and pain after Liposuction. The study also aims to explore changes in patient satisfaction. The main questions this study seeks to answer are: * Does CO2 lift reduce the extent of bruising at 7 days post-surgery? * How does CO2 lift impact patient-reported pain and satisfaction? In this study, researchers will compare CO2 lift to a placebo (Vaseline) to see if the intervention has a positive effect. The study procedures include: * Baseline data collection of sociodemographic variables. Data collection of surgical variables, adverse events, pain scores, and satisfaction scores. * During the liposuction procedure the patient will receive CO2 Lift application to one arm, and/or one glute, and/or one half of the lower abdomen, and placebo (Vaseline) to the contralateral part. * Apply CO2 lift and Vaseline immediately after surgery, 12 hours later, and then once a day for 3 to 5 days depending of the risk of the flap/skin. * Postoperative follow-up with photos of treated areas at 24 hours, 3 days, and 7 days, with bruising quantified using Image J software.
