Hi there. At Monroe Comprehensive Laser Center in Monroe, Mi, Dr. Katz uses Morpheus daily to help rejuvenate and tighten skin and muscle. Morpheus is great because it penetrates deeply enough to send that radiofrequency energy just where it needs to be to induce collagen production, tighten muscle, tighten skin, and even get rid of a little bit of fat. We have seen results last a year and a half or more. However, like with every skin procedure, the results are dependent on a team approach between doctor and patient. You need to keep up a healthy skin regimen, avoid excess sun exposure, eat a health diet, not change you weight significantly, etc. All of these factors can effect your final results and how long they last. Hope this helps!
