Safety of Helium-based Plasma Technology for Coagulation of Soft Tissue: A Retrospective Review.

Background: The subdermal application of energy using a helium-based plasma radiofrequency (RF) device has been shown to improve skin laxity. Helium-based plasma RF technology (Renuvion; Apyx Medical, Clearwater, FL) utilizes RF to ionize helium into an electrically conductive plasma capable of coagulating and contracting soft tissue with high precision and minimal thermal spread. This study provides information on the early use of the new generation of electrosurgical generator (APYX-RS3) containing a feature that allows for quantification of the amount of energy delivered to tissue during treatments.
