<P><I>Background</I>: Recently, a novel combined multi-polar radiofrequency and pulsed electromagnetic field device was developed for non-ablative skin tightening. However, little is known about the clinical effects of this device. <I>Objectives:</I> The present study evaluated the clinical efficacy and safety of the multi-polar radiofrequency and pulsed electromagnetic field device. <I>Materials and Methods:</I> Ten Korean patients underwent eight treatment sessions over 6 weeks. Clinical photographs of the skin were taken before and after the treatment at each week of treatment. Satisfaction score (0; dissatisfied, 5; neutral, 10; very satisfied) and pain score (0; no pain, 10; too painful) was determined using weekly questionnaires. A dermatologist evaluated the improvement of facial skin aging, including laxity, nasolabial fold, facial contour, skin texture, and skin color tone. <I>Results</I>:The mean satisfaction score was high (>8) and the mean pain score was low (1.5). Improved skin laxity, nasolabial fold, and facial contour were observed in four, one, and three patients, respectively. Skin texture and skin color tone improved in 90% and 70% of the patients, respectively. <I>Conclusion:</I> The novel combined multi-polar radiofrequency and pulsed electromagnetic field device is safe and effective for rejuvenating aged skin in Korean subjects.</P>

<P>Bipolar radiofrequency (RF) is capable of delivering higher energy fluencies direct to the dermis through a needle electrode. This produces heat when the tissue electrical resistance converts the electric current to thermal energy in the tissue. A 38-year-old man visited our clinic for reduction of submental fat deposit, but otherwise in overall good health. After deciding to perform phosphatidylcholine (PPC) injections subcutaneously, we concerned about edema and swelling of injection site lasted several weeks. We wanted to shorten the period of edema and swelling, and we decided to add bipolar RF treatment. After 1 week of PPC injection combined with RF treatment, overall volume of jowl was decreased and edema and swelling on the PPC injected site markedly subsided. This reduction of fat deposit lasts longer than 1 year. Follow-up for 1 year demonstrated that the cosmetic results were well maintained.</P>
