A pilomotor effect stimulating device is designed to electrically stimulate the arrector pili muscles of the skin to cause a pilomotor reaction in which goosebumps are formed in the affected area and the hairs are raised away from the skin. The device has a handle and a head at one end of the handle carrying electrodes for skin application. An electronic control unit in the handle is connected to the handles and includes a pulse generator configured to produce a pulsed electrical signal at the electrodes which is designed to stimulate the arrector pili muscles in the vicinity when the electrodes are applied to the skin. The device may be used as a shaving aid to raise the hairs in an area to be shaved, making it easier to cut the hairs closer to the skin when shaving.
