Hello, hope you are well. What you are told is correct--microneedling with RF (commonly marketed as Morpheus) tightens the skin. It does this by stimulating collagen production within the dermis. The effects are usually apparent within a few days to a few weeks and patients often continue to see improvement up to 3 months after treatment. But alas, the aging process continues, and sometimes we perform the treatment for a few sessions to reach a satisfactory endpoint. If you have significant marionette ('frown') lines, turkey neck, and jowls, it is very unlikely to sufficiently tighten the skin to make these issues disappear. For mild problems, I sometimes combine the Morpheus treatment with FaceTite (RF applied deep to the skin), and for moderate to severe jowling etc I generally recommend a facelift if you are a suitable candidate. Hope this helps! Best,Dr. Tower
