Skin Care Implement and System

Abstract:

In one embodiment, a personal care implement is disclosed. The personal care implement has an emitting end and an electromagnetic source for projecting electromagnetic radiation onto an area of skin to treat a skin condition. A light sensor is configured to sense an amount of ambient light present at the emitting end. A controller instructs the electromagnetic source to begin projecting only when the light sensor senses that the amount of ambient light at the emitting end is below a predefined threshold.
