Nonsurgical nonablative treatment of aging skin: radiofrequency technologies between aggressive marketing and evidence-based efficacy.
The gold standard treatment for the many aesthetic aspects of aging has for many years been surgery in its many forms. However, with increasing patient demand for cosmetic rejuvenation and with the strong desire and drive by patients to attain aesthetic enhancement with minimal risk and rapid recovery, there has been a strong surge inspiring the field of nonsurgical skin rejuvenation. Traditionally, most of the nonsurgical methods have centered around those that destroy the epidermis and cause a dermal wound, with resultant dermal collagen remodeling and secondary skin tightening and rhytid improvement. Currently, there is growing interest in a wide range of nonablative interventions that, predictably, are claimed to rejuvenate skin and subcutaneous tissue "safely and effectively." Although several nonablative systems have been cleared by the U.S. Food and Drug Administration (FDA) for the purpose of skin rejuvenation and despite significant reported improvement in the appearance of signs and symptoms of photoaging by relatively noninvasive means, the clinical results have been generally less than impressive, with most subjects showing only mild improvement. The current review aims at summarizing the various nonablative methods currently in use for skin rejuvenation and to evaluate the evidence-based efficacy of a particular nonablative radiofrequency (NARF) method: monopolar radiofrequency.
