Ultherapy is also a highly effective procedure and can be used to treat not only the neck and jowls as ThermiRF can, but also the cheeks, chest and eye areas. As both a surgical facelift and ThermiRF affect the SMAS, so does Ultherapy! We can easily see that in order to be effective, the procedure must affect the SMAS. The difference is that Ultherapy is applied directly through the skin using HIFU (High Intensity Focused Ultrasound). The tissue is directly visualized via ultrasound so we know exactly where the energy is being delivered. There is some discomfort as the ultrasound waves travel through the skin to the underlying SMAS target tissue but is well tolerated and well worth it in the end. There is no real recovery time, outside of mild redness and swelling. One can resume social obligations and public appearances immediately. Ultherapy also targets the dermis to stimulate collagen production with a second pass that is highly recommended. The lips and delicate skin under the eyes are also very responsive to this technology.
