• CR-SMFRS grade of 4 (extreme) as determined by the evaluating investigator at screening.
• Dissatisfaction with the submental area expressed by the subject as a rating of 0, 1 or 2 using the Subject Self Rating Scale (SSRS) as determined at Screening visit.
• History of stable body weight confirmed by the subject, for at least 6 months prior to the first treatment session.

• Subject has read and signed the study written informed consent form.

Exclusion criteria

• Subject has excessive skin laxity, as determined by the evaluating investigator, in the neck or chin area or other anatomical feature (e.g., predominant subplatysmal fat, loose skin in the neck or chin area, prominent platysmal bands) for which reduction in the submental fat may result in an aesthetically unacceptable outcome.
• There is evidence of any cause of enlargement in the submental area (e.g., thyroid enlargement, cervical adenopathy) other than localized submental fat.
• Subject has a history of trauma associated with the chin or neck areas, which in the judgement of the investigator may affect evaluation of safety or efficacy of treatment.
• Subject has a history of treatment with CoolSculpting or KYBELLA® in the intended treatment area or has a history of any intervention to treat submental fat (e.g., liposuction, surgery, or lipolytic agents).
• Subject has a history of treatment with radiofrequency, micro-focused ultrasound, laser procedures, chemical peels, or dermal fillers in the neck or chin area within 12 months before the first treatment session.

• Subject is unable or unwilling to comply with the study requirements.
• Subject has received treatment with an investigational device or agent within 30 days before the subject's first treatment session.
