The need for cosmetic facial enhancement procedures with minimal down time and low risk has led to the development of methods for non-surgical skin rejuvenation. Various ablative lasers were developed, which remove the full skin surface in a controlled manner. However, the prolonged recovery and the significant risks prompted the development of fractional lasers which ablate the skin in a fractional manner, leaving untreated areas to improve healing process. In the past few years, fractional radiofrequency (RF) systems have been introduced that enable controlled skin resurfacing accompanied with dermal collagen remodeling. The new TriFractional technology from Pollogen® is designed to enable skin resurfacing and treatment of wrinkles using RF energy. The objective of the current research was to evaluate the safety and effectiveness of the novel TriFractional technology using the TriFractional applicator (A3F) for micro-ablative skin resurfacing and the treatment of wrinkles and acne scars. Methods: Healthy volunteers consented to undergo TriFractional treatments for various aesthetic indications. In addition, in-vivo and ex-vivo histologycal results showing immediate and long term effects of the TriFractional technology were obtained. A portion of the subjects underwent the complete TriLipo Med<sup>TM</sup> Procedure which includes 2 TriFractional treatments spaced one month apart, with 2 TriLipo RF + Dynamic Muscle Activation (DMA) face treatments two weeks after each TriFractional treatment. Results: Subjects experienced an improvement of wrinkles, skin texture and acne scars along with facial contouring. No significant adverse effects were detected post-treatment. Histology findings demonstrated immediate and long term TriFractional effects on both epidermal and dermal skin layers. Conclusions: TriFractional is a promising technology for skin resurfacing, treatment of wrinkles and improvement of additional aesthetic indications such as acne scars. The TriLipo MED<sup>TM</sup> procedure is a unique combination approach for total facial rejuvenation and contouring
