The invention relates to facial stimulation apparatus configured to be worn on the a user's head, and which uses the ear (14) as an anatomical reference to ensure correct and repeatable placement of skin electrodes (16a, 16b) over the human facial nerves (12a-e) to facilitate Electrical Muscle Stimulation (EMS). Use of the ear as an anatomical reference ensures repeatable positioning of the electrode in contact with a single predetermined localised region of the face corresponding to the insertion of the facial nerve truck (10) overlying the sylomastoid foramen. The apparatus overcomes problems inherent in known devices and, in particular, requires no anatomical knowledge on the part of the end user for its safe and most effective placement.
