A single-arm, multicenter interventional clinical study will be conducted. The objective is to evaluate the safety and efficacy of the cryolipolysis technique. Approximately 372 participants will be included. After analyzing the items listed above, the participants in each study will be divided into 3 distinct intervention groups. The individuals included in the study will undergo anamnesis and data collection.

The participants in each study will be divided into 3 distinct intervention groups (Grupo 1: aplicador 360° M - Região abdominal; Grupo 2: aplicador 360° G - Região abdominal; Grupo 3: aplicador de placas - Região dos flancos). After analyzing the inclusion and exclusion criteria of this study, the individuals included in the study will undergo anamnesis and data collection after the procedure and 6 weeks and 20 weeks after: photographic capture, bioimpedance, perimetry, adipometry and ultrasound imaging of the treated area, in addition to a pain and patient satisfaction questionnaire.

Inclusion Criteria:

• The participant (healthy volunteer) who has read and signed the informed consent form for the study.

• Subject has not changed in weight more than 5% of body weight in the previous month.
• Subject agrees to maintain his/her weight (i.e., within 5%) by not making major changes in his/her diet or exercise routine during the study.

• Recent surgery at the treatment site;
• Regular use of anti-inflammatory medications;
