The provided source offers an overview of body sculpting certification, particularly focusing on the possibility and limitations of free online training. It explains that while free resources can introduce fundamental concepts and common non-invasive procedures like ultrasonic cavitation and radiofrequency skin tightening, they typically lack accreditation, in-depth curriculum, hands-on practice, and eligibility for liability insurance.
