The Wood's light or Wood's lamp was invented by the physicist Robert Wood. It's a device that emits long-wave ultraviolet light. When used in a dark room, it can help diagnose various skin conditions, and therefore will be an essential tool to select accurate treatments and appropriate home care products.
