Multiple therapies involving ablative and nonablative techniques have been developed for rejuvenation of photodamaged skin. Monopolar radiofrequency RF is emerging as a gentler, nonablative skin-tightening device that delivers uniform heat to the dermis at a controlled depth. We evaluated the clinical effects and objectively quantified the histologic changes of the nonablative RF device in the treatment of photoaging.
Standard photographs and skin biopsy specimens were obtained at baseline, and at 3 and 6 months after the start of treatment. We performed quantitative evaluation of total elastin, collagen types I and III, and newly synthesized collagen using computerized histometric and immunohistochemical techniques.
Blinded photographs were independently scored for wrinkle improvement. RF produced noticeable clinical results, with high satisfaction and corresponding facial skin improvement. Compared with the baseline, there was a statistically significant increase in the mean of collagen types I and III, and newly synthesized collagen, while the mean of total elastin was significantly decreased, at the end of treatment and 3 months posttreatment. A limitation of this study is the small number of patients, yet the results show a significant improvement.
Although the results may not be as impressive as those obtained by ablative treatments, RF is a promising treatment option for photoaging with fewer side effects and downtime. T here are two clinically and biologically distinct aging processes affecting the skin. For more than half of a decade, many different laser and other light-based systems have been developed and evaluated for their capability to reverse photodamage and age-associated rhytides, a process referred to as photorejuvenation.
However, laser light can be diffracted, absorbed, or scattered, and only small portions of the emitted energy reach the target of concern. Consequently, the effects are proportionally reduced. The energy produced is not liable to be diminished by tissue diffraction or absorption by epidermal melanin. As such, RF-based systems are appropriate for any skin type. This study was conducted on a cohort of 6 female volunteers who desired an improvement in the appearance of facial skin laxity and wrinkles.
