What type of light does a Wood's lamp use?

A Wood's lamp uses filtered black light, which is a type of ultraviolet (UV) light. This specific wavelength of light is effective in revealing certain skin conditions and abnormalities that are otherwise not visible to the naked eye. When the skin is exposed to this UV light, it can fluoresce, allowing estheticians to identify issues such as fungal infections, pigmentation disorders, and other skin irregularities. The unique properties of filtered black light make it a valuable tool in skin analysis, helping practitioners better understand the conditions they are treating and improve their clients' skincare regimens.
