Should you need to replace an electrode, we offer the option of purchasing an additional electrode. Choose 1 electrode from these 4: the Mushroom, Comb, Spoon and Curved electrodes are available. Please note: when going through the shopping cart checkout process, please specify in the "customer notes" field which electrode you would like to receive. Also, we will assume you need to replace the electrode which fits the High Frequency/Violet Ray device. If you need to replace an electrode for the Violet Ray-Professional Edition, please also specify this in the "customer notes"
