What color does normal skin appear under a Wood's lamp?

Under a Wood's lamp, normal skin typically appears blue. This instrument utilizes ultraviolet light to examine the skin closely. Normal, healthy skin absorbs the UV light in a way that reflects a blue color, indicating no significant abnormalities or issues beneath the surface.

Conversely, other colors indicate various skin conditions. For instance, green typically suggests the presence of certain bacterial infections, yellow may indicate various skin conditions or pigmentation issues, and purple is often associated with areas of inflammation or edema. Understanding these color indicators is essential for skincare specialists, as it aids in identifying skin conditions and tailoring appropriate treatments.
