Thermage is a skin tightening procedure that uses radiofrequency energy to tighten and rejuvenate the skin on the face. It treats imperfections such as wrinkles, uneven skin tone and unsightly bulges on the face. Thermage is non-surgical and induces the production of collagen. The radiofrequency device is passed over the skin. Each time the device touches the skin of the patient, there is a brief cooling effect and then a heating sensation that means the energy is going deep into the skin to start the production of collagen. The procedure takes 45-60 minutes for the face and 90 minutes for the rest of the body.
