Endermology is a nonsurgical procedure to correct cellulite but despite being FDA approved, its efficacy is still debated. The mechanism utilizes a hand-held device to deliver pulses of electrical heat and massage with rollers applied to areas of cellulite. 

External radiofrequency, i.e. Thermage® delivers non-invasive external radiofrequency waves to the skin and fat and is proposed to encourage new collagen deposition and dermal skin tightening. Results have been sporadic and longevity is unclear. Tolerance is good as the discomfort and downtime are minimal. 

Mesotherapy involves the injection of a variety of medications to lyse and destroy fat cells, either cellulite or focal fat deposits. Despite being minimally invasive, mesotherapy is not without serious risks such as infection, tissue damage, allergic reaction, damage to blood supply, and excessive removal of fat.

All of the descriptions for the various procedures are condensed from the text of the upcoming textbook written by Dr. Christopher Park and Dr. Malcolm Marks and are copyrighted, "The Artistry of Plastic Surgery: Exploring the Experience” .
