Wood lamp uses what kind of light?

Wood lamp uses ultraviolet light. This long-wave UV light excites substances in the skin so they fluoresce, helping you see pigment changes, bacterial or fungal elements, and hydration status that aren’t always visible under normal light. Visible light would only show surface color, not fluorescence; infrared provides heat awareness and doesn’t produce the characteristic glow; X-ray involves ionizing radiation and isn’t used for skin evaluation. So ultraviolet light is the right type for this examination.
