The Woods Lamp is a diagnostic tool that emits ultraviolet (UV) light, commonly used in dermatology. It helps dermatologists examine the skin for various conditions, including fungal infections, pigmentation disorders, and certain skin diseases. When the UV light is directed onto the skin, it reveals changes in pigmentation and highlights areas that may indicate underlying issues, such as bacterial or fungal infections. The Woods Lamp is a valuable tool for skin assessments and aids in making accurate diagnoses.
