What kind of light is used in the Wood's lamp?

The Wood's lamp utilizes a black UV light, which emits ultraviolet radiation. This specific type of light is particularly effective in skincare and esthetics because it allows practitioners to detect various skin conditions and issues that are not visible under regular lighting conditions.

For instance, the Wood's lamp can help in identifying the presence of fungal infections, certain bacterial infections, pigmentation irregularities, and areas of skin that more readily reflect UV light, such as those affected by sun damage. The black light emitted by the Wood's lamp causes certain substances in the skin to fluoresce, making it an invaluable tool in an esthetician's toolkit for assessing skin health.

Other light types mentioned do not serve the same function. White visible light would not provide the necessary contrast to reveal hidden skin conditions. Blue LED light is primarily used for targeted treatments of specific concerns like acne. Red infrared light is associated with promoting healing and reducing inflammation but does not have the diagnostic capability provided by the Wood's lamp’s black UV light.
