Body-sculpting procedures are becoming increasingly popular. Although lipoplasty remains the most common procedure, nowadays, the risks, costs and lengthy downtime associated with surgical procedures for fat reduction have led to the development of a number of non-invasive techniques. Non-invasive body contouring now represents the fastest growing area of Cosmetic Dermatology. This review describes the mechalipectonism of action, efficacy, safety, and tolerability of suction, ultrasound, laser and radiofrequency assisted lipoplasty, ultrasound liposuction, laser assisted liposuction, as well as cryolipolysis, focused ultrasound, and high intensity focused ultrasound and injection lipolysis, the noninvasive methods with temporary effects such as radiofrequency and low-level laser therapy are mentioned as well. The articles cited were identified via different PubMed searches. Invasive procedures have a lengthy recovery and more risks; the non-invasive treatments reviewed can be administered on an outpatient basis, have fewer complications and require analgesia but no anesthesia. The published literature suggests that, although liposuction continues to be the most common procedure, noninvasive techniques for subcutaneous fat reduction such as cryolipolysis, focused ultrasound and high intensity focused ultrasound may be appropriate options for non-obese patients requiring modest reduction of adipose tissue.
