Exilis is a FD- approved procedure that reduces fat. It tightens and improves the skin's quality. The RF energy used during the treatment heats the deeper layers of the skin causing fat cells to shrink as the skin contracts and stimulates new collagen. The Exilis device is glided across the areas being treated delivering RF energy as it's moved along. The precisely controlled radiofrequency energy heats the deeper layers of the skin. This heat causes fat cells to shrink and contracts the skin tissue while stimulating new collagen production in the process.
