Thanks for your question. It actually covers a lot of ground. If you try to get an idea of the science behind the minimally-invasive aesthetic techniques from the Internet, it is often hidden behind a myriad of cooler sounding marketing labels. As one of the first 25 surgeons in the country trained in the use of the FaceTite technique back in 2016 (Luminary status), let me give you a little of the science behind using radio wave length energy to tighten tissues, expectations of the treatment, and long-term results compared to other techniques. I have used radio-frequency energy delivery devices since 1991. Back then, very high energy levels were used to cut and scar down tissue to treat cancer, snoring, nasal obstruction, even prostate enlargement. A needle-like tip was inserted into the tissue for treatment, and a grounding pad was applied to the small of your back. The energy levels applied were much higher, and much of it would head to the grounding pad. This type of monopolar energy delivery lacked precision, and required reaching temperatures of 85 degrees Celsius (185 degrees Fahrenheit, ouch!). Remember, we were trying to scar, and destroy tissue, not tighten tissue aesthetically. With a lot of engineering, and years of trial by starting slow and using very low levels of energy delivered over many, many sessions, products like Fractora RF, FaceTite, and BodyTite developed by the folks at Inmode/Invasix, now allow me to tailor radio-frequency delivery to various levels of the body, and face. Additionally, all of the energy delivered by the Inmode/Invasix products are bipolar, allowing more precision, and control. Bipolar is good. All the energy stays between the two bars, or needles or trocars. There is no grounding pad placed several feet away from the treatment site as with any monopolar technique. Monopolar techniques such as Thermage, and Pelleve use the old grounding pad on the lower back style of delivery. Monopolar techniques are fine, but require multiple treatment sessions, and address only the very superficial lines. I use these techniques only for touch-up. There is no "wow" factor to the Thermage, and Pelleve treatments. They get a lot of press because most anyone can treat you, nurses, dermatologists, even medical assistants. However, that may be all you need. Think of the face and neck as composed of layers beginning with the skin surface, then soft tissue, then fat, then the surface of underlying muscle. The surface is treated with bipolar radiofrequency (RF) applicators like, Forma, and FormaPlus. The next layer requires tiny needles to get the RF energy deeper, such as Fractora RF. Finally, fatty tissue can be reached with FaceTite. Yes, as you go deeper, the technique is more invasive. FaceTite can only be offered by surgeons with training in liposuction, and surgical technique and sterility. I now have the results of FaceTite patients out more than a year (I began in 2016). My results are 10% improvement in soft tissue tightening on the day of treatment, 50-60% improvement at 3 months out, and 75% at 6 months. The presentations I have attended show improvement out to 2 years. Ultherapy uses ultrasound wavelength energy to heat tissue. Realize, ultrasound treatment of soft tissue has been around since World War II, and has its maximum effects at a depth of 1 to 5 cm in the human body. Hence, it works great for joint and muscle injury; as for skin and soft tissue, hum. It can be delivered by most anyone, but the science isn't there.
