Abstract

Abstract: Background and Objectives: This feasibility study describes the effects of Nano‐pulse stimulation™ (NPS™) technology using the CellFX™ System on acne vulgaris of the back with the objectives of demonstrating safety and effectiveness. The CellFX System applies nanosecond pulses of electrical energy to induce highly localized regulated cell death (RCD) in the cellular structures of the targeted zone with no thermal effect on the tissue and negligible effects on surrounding non‐cellular components. Study Design/Materials and Methods: Seventeen subjects were enrolled at two sites with thirteen subjects completing treatment. Three 7 X 7 cm regions containing at least five bacne lesions each were identified, one region treated with the CellFX across three treatment sessions, the second region treated as a sham using microneedle tip placement without delivering energy, and the third as an untreated control. Results: CellFX‐treated areas showed an average reduction of acne lesions of 82% by 90 days post‐last procedure. Acne improvement was observed in 100% of CellFX‐treated regions compared to 39% improvement in Sham regions and 31% improvement in the control regions. The most common skin effects were erythema and hyperpigmentation observed in 23% and 92% of the subjects, respectively, at the last timepoint. No serious adverse events were reported. Conclusions: CellFX is a safe and effective procedure for clearing back acne.
