Question : Does ultherapy remove fat or just tighten the skin? Are the results permanent?
Answer : In reality, Ultherapy neither removes fat nor tightens the skin but, in fact, targets the deeper layer of the face in the area of the SMAS where there is a significant amount of collagen. The ultrasound waves heat the collagen to the point where they denature and this creates a healing response where new collagen is deposited, which in turn then tightens. When we treat an entire face with the Ultherapy device, we will do upwards of 8000 small thermal injury zones where new collagen is going to be deposited and each zone will create a small amount of tightening. When these are all added together, we get brow lifting and cheek lifting and improvement in jowls and laxity under the chin. In my opinion, the results are similar to other devices such as laser resurfacing or even surgical results in that the tissue heals and now we start the aging process from a new reference point so, in effect, the patient that undergoes an Ultherapy treatment will always look better than if they had never undergone a treatment, but they will eventually age out of the improvement that was obtained.
