Evaluation of the multiple pass, low fluence algorithm for radiofrequency tightening of the lower face

Background and Objective Non‐ablative monopolar radiofrequency technology delivers heat to the deep dermis and subdermal layers of the skin to improve facial laxity. The purpose of this study is to evaluate the multiple pass, low fluence treatment alogrithm for lower face laxity. Study Design/Materi...

Description
Summary:Background and Objective Non‐ablative monopolar radiofrequency technology delivers heat to the deep dermis and subdermal layers of the skin to improve facial laxity. The purpose of this study is to evaluate the multiple pass, low fluence treatment alogrithm for lower face laxity. Study Design/Materials and Methods Sixty‐six subjects with moderate facial laxity were treated with a maximum of 5 passes over the lower face and neck. Treated areas were evaluated using the Leal Laxity Classification System and by independent photographic assessment. Measurements of skin stiffness and energy absorption were taken with the BTC2000 device. Results The average treatment level was 62.0 (83 J/cm2) with 556 pulses per treatment. At the 6 month follow‐up visit, 92% of patients had a measurable improvement in overall appearance. Independent photographic review revealed improvement in 84% of subjects at 6 months. Objective measures utilizing the BTC2000 device demonstrated improvement that diminished with time. Conclusion The low‐fluence, multiple pass technique is an effective algorithm for radiofrequency skin tightening. Lasers Surg. Med. 39:210–217, 2007. © 2007 Wiley‐Liss, Inc.
