Scientists have used a free electron laser at certain wavelengths to heat up fat. This results in the fat being excreted by the body without any damage to the skin. The research is being conducted at Massachusetts General Hospital, and the process is called photothermolysis. According to the scientists, the method may be used to treat cellulite, acne and heart disease.
