Thermage is a non-surgical skin tightening treatment that does not require general or local anesthesia. A topical anesthetic may be applied before your Thermage procedure to minimize discomfort. Thermage technology also produces a cooling effect on the surface of your skin to ensure comfort and maintain skin health. During treatment, the Thermage device is placed on your skin and begins delivering heat energy to the skin’s deeper layers to spur on the production of new collagen fibers. After radio frequency energy is delivered, the skin is once again cooled before the end of your Thermage treatment.
