Reduction of erythema after laser on rosacea by subthermal 448 khz monopolar radiofrequency

Excellent results are usually obtained when facial benign vascular alterations such as erythrosis and couperosis are treated with vascular laser (pulsed dye, KTP, Neodimiun-YAG) or with Intense Pulsed Light (IPL). However, the erythema occurring at hours or days after such treatment may hamper the patients’ ability to go back to their daily lives and increase the risk of adverse effects. The 448 kHz capacitive/resistive monopolar radiofrequency system is based on the subthermal electrical stimulation of tissues, enabling the restoration of ionic balance at cell level. For this study, this system was applied on patients with erythematotelangiectatic rosacea before and immediately after treatment with pulsed dye laser. This technology helps restrict the progression of treatment-related erythema, thereby reducing recovery time and the risk of more serious adverse effects.
