This is the first device approved by the FDA to actually "tighten" skin. This technology uses radio waves to penetrate deep into the dermis without breaking the epidermis and stimulate contracture of the collagen and further production of collagen. Over the course of four to six months, lifting of the skin has been noted. Thermage works by delivering deep intense heat into the skin without injury to the epidermis or outer layers. With the gentle touch of the device tip, the surface of the skin is cooled, while the deeper tissue is altered by radiofrequency heating. This not only tightens deeper skin tissue, but jumpstarts new collagen production, which occurs over a period of time.
