BACKGROUND: 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.
OBJECTIVES: The present study evaluated the clinical efficacy and safety of the multi-polar radiofrequency and pulsed electromagnetic field device.
MATERIALS AND METHODS: 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.
RESULTS: 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.
CONCLUSION: The novel combined multi-polar radiofrequency and pulsed electromagnetic field device is safe and effective for rejuvenating aged skin in Korean subjects.
