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.

Reliant Technologies has received FDA approval for its 510(k) submission for its Fraxel repair laser system for Fractional Deep Dermal Ablation (FDDA™) treatment. The system is used for treating wrinkles, rhytides, furrows, fine lines, textural irregularities, pigmented lesions and vascular dyschromia. The Fraxel repair laser system already had clearance for ablation, coagulation and skin resurfacing.
