Hello, and thank you for your question! FaceTite provides a dramatic improvement in skin laxity on the face and neck. FaceTite utilizes minimally invasive radiofrequency energy to melt fat and tighten skin. Any areas on the face and neck with saggy skin can be treated. This includes the double chin, jowls, and other areas with deep lines and loose skin.Facetite results vary from person to person. I do not know how effective Facetite would be for you, especially if you do not have much fat to begin with, and are looking to build more collagen. You would probably be a candidate for Morpheus 8, which is a newer microneedling technique that produces collagen and firms/tightens the face and neck. Patients have found this to provide amazing results, regardless of how thin they are. You may need multiple treatments with Morpheus 8, but patients say it is undoubtedly worth it!!Please be sure to see a board-certified plastic surgeon you feel comfortable with. Best of luck! **Please see my attached link-you will find videos at the bottom of the page that have more information on Facetite and Morpheus 8. James L.
