Regarding Thermitight- What if I do not have fat, just loose skin? (Photo)

Thermi is a great minimally invasive method to tighten neck skin.  It doesn't do too as much for neck fat.  A neck/facelift is still the gold standard for neck tightening and has a greater effect than Thermi.  Mild to moderate neck laxity is more responsive to Thermi than severe laxity.  

Thermi, aka ThermiTight, is designed for the surgeon to set the parameters to only tighten connective tissue and produce collagen, or to reduce fat.  Certainly, for those with thin neck skin, the settings are set to avoid fat reduction, and the surgeon constantly monitors the internal temperature, realtime and moves the instrumentation to ensure that the tissue isn't heated in one spot for too long. With attention to detail, results are very gratifying in most cases. Our patient satisfaction rating for Thermi Tight is very high.The information provided in Dr. Shelton's

We often use ThermiTight at my practice to tighten skin without removing fat. It is an effective procedure that may also be combined with other skin tightening procedures to achieve the desired result, like ThermiSmooth, which is another device which uses the ThermiRF system non-invasively to tighten skin without affecting fat. I recommend visiting a board-certified dermatologist with experience performing skin tightening procedures for an in-person consultation to see what treatment is best for you.
