This study is designed to evaluate the safety and effectiveness of a low-level near-infrared LED light device for relieving itch. The device is non-invasive, does not break the skin, and does not produce heat. Near-infrared light has been used in other medical settings and is known to interact with skin and nerve pathways. In this study, researchers are examining whether this light can be safely applied to the skin and whether it may help reduce itch by affecting signals involved in itch sensation.
