The CellSound Aesthetics BRH-A2 is a non-invasive medical aesthetic system that uses ElectroSonic Resonance (ESR) technology to perform body contouring, facial rejuvenation, and tissue regeneration. Derived from the clinical BRH-A2 Wound Healing System—a medical device originally developed by BRH Medical to treat chronic ulcers by improving deep tissue blood flow—the aesthetic version repurposes this combination of therapeutic ultrasound and electrostimulation fields for non-surgical cosmetic enhancements.
