The desensitizing device contains an electrical stimulation member optionally configured on a support member. The electrical stimulation member contains a control circuit and at least two electrodes. The control circuit generates a stimulating current to the electrodes. By configuring the electrodes contacted with the skin, the stimulating signal produced by the control circuit is conducted to the electrodes and provides a subcutaneous nerve stimulation through the skin. The subcutaneous nerve is as such temporarily numbed and desensitized.
