“…Another adverse reaction found was fat atrophy, which occurred in just one patient on his frontotemporal left area. 6 This patient observed some depressions on this side of the face 1 month after treatment but was not bothered by them.…”

In comparison with other studies, we have found a very low incidence of posttreatment erythema and edema. On the other hand, the incidence of second-degree burns is somewhat higher. This might be due to the fact that in other studies higher energy settings have been used but without overlapping pulses. Monopolar radiofrequency is a safe method of treating the skin of the face and neck, and it should be done at moderated energy settings with no immediate overlapping in order to avoid overheating and undesirable side effects.

“…29 In contrast to the dermis, fatty tissue may more readily heat because of high inherent electrical resistance. The temperature in the fat is estimated to rise 7 times that of the dermis when treated with a radiofrequency device.…”

Nonablative procedures for facial rejuvenation have become increasingly popular. One such method to improve laxity and diminish rhytids is monopolar capacitively coupled radiofrequency (MRF). The authors discuss clinical studies using MRF. The authors also discuss their clinical experiences as well as recommendations for optimal results. MRF using the Thermage CPT system (Solta Medical, Hayward, California) offers minimal downtime with a favorable side-effect profile. Although there are many radiofrequency devices on the market for aesthetic use, MRF has the most clinical trials to date to support its use as an effective, evidence-based modality to improve rhytids and tighten the skin.

Abstract-Simultaneous exposure to multiple electromagnetic signals with widely differing carrier frequencies is a reality of daily life, but its possible effects on health are unknown. In this study, we exposed rats to non-thermal levels of 900 and 2450 MHz TEM-mode radiation, applied individually or simultaneously, and we obtained estimates of 1 g mean SAR (specific absorption rate) in various tissues using a numerical model of the rat and finite-difference timedomain software. The experimental system comprised a GTEM (gigahertz TEM) chamber connected to two vector signal generators, a signal mixer and amplifier, a directional coupler, a spectrum analyzer and a power meter. Tissue sections from rats sacrificed 24 h after exposure, and from negative controls and positive controls exposed to gamma radiation, were stained with haematoxylin-eosin for evaluation of general cell morphology and with DAPI (4', 6-diamidino-2-phenylindole) for evaluation of apoptosis. Lesions, tissue destruction and apoptosis were only observed in positive controls. The results for rats exposed to either frequency, or to both simultaneously, were similar to those of unexposed negative controls. It remains to determine whether chronic exposure is similarly innocuous.
