The Pros and Cons of HIFU and Thermage for Skin Tightening

hifu and Thermage both work to non-invasively stimulate collagen to create lifting and tightening of the skin. HIFU uses ultrasound technology, whereas Thermage uses radiofrequency. Thermage uses radiofrequency to heat up the deep skin.
hifu therapy is a safe and effective non-invasive ultrasound treatment that can lift and tighten facial skin and muscle without downtime. HIFU uses focused ultrasound to treat the skin by increasing collagen in the skin and creating lifting, firming and tightening effects. It can successfully treat the lines along the upper lip that are most difficult to treat with injectables.
hifu machine reliably places energy in the dermis and SMAS layer. The energy is always above the critical temperature to cause tissue contraction and collagen formation. Depending on the patients needs HIFU can target up to three layers of skin, 1.5 mm,3mm, and 4.5 mm in depth. Thermage only targets tightening. 
Thermage is a radio frequency technology device that heats the skin and subcutaneous tissue superficially. Thermage is very unreliable in it’s placement of energy through the skin and therefore it’s results are very unreliable. 
Although Thermage has been improved over the years, it's main problems have been a very high patient dissatisfaction rate and a very painful patient experience. HIFU can cause discomfort as well, but if patients are enduring pain, they appreciate a result that they can notice. Patients can be given oral medications or local anesthetic nerve block injections if needed, but the majority of HIFU patients are able to tolerate a properly performed treatment with just a cold air blowing on their skin.
