A portable electrically-powered device intended to emit both red and blue light for the treatment of a facial skin condition (e.g., acne, hyperpigmentation) by the patient in the home. It includes integral lights with a controller/controlling interface (to pair with an off-the-shelf computer/smartphone), and may be available in a variety of forms (e.g., a face-worn light mask with controller, hand-held light unit). It is not intended for use with a photosensitizing agent. This is a single-patient, reusable device.
