The type of light utilized in a Woods lamp is ultraviolet light. A Woods lamp emits a specific wavelength of ultraviolet light, typically in the shortwave range, which is used in skin analysis and dermatological assessments. When the lamp is directed at the skin, certain substances and skin conditions fluoresce under this light, assisting estheticians and dermatologists in identifying issues such as pigmentation disorders, bacterial or fungal infections, and other skin anomalies.

Although the term "black light" is often used colloquially to describe UV light, it specifically refers to the longer wavelength UV-A light typically used in entertainment and other non-medical applications. In the context of skin analysis, the precise nature of the UV light emitted by a Woods lamp is crucial for the accurate assessment of skin health.
