Nonablative cutaneous remodeling using radiofrequency devices.

In recent years, several new radiofrequency devices have been introduced for treatment of a variety of skin conditions, particularly, skin wrinkling and laxity. These nonsurgical systems induce tissue tightening and contour changes through dermal collagen remodeling without disruption of the overlying epidermis, obviating a significant recovery period or risk of serious adverse sequelae. As such, radiofrequency-based systems have been used successfully for nonablative skin rejuvenation, atrophic scar revision, and treatment of unwanted hair, vascular lesions, and inflammatory acne.
