Normal healthy skin appears as what color when viewed under a Wood's lamp?

Normal healthy skin appears blue-white when viewed under a Wood's lamp. This specific color indicates that the skin is free from any fungal infections or significant skin disorders. The Wood's lamp emits ultraviolet light, which causes certain substances in the skin to fluoresce. Healthy skin will reflect this specific light in a blue-white hue, serving as a baseline for professionals to assess skin conditions.

In contrast, other colors observed under the Wood's lamp can indicate various skin issues. For example, yellow fluorescence might suggest the presence of certain skin lesions or conditions, while green can indicate the presence of bacteria or fungal infections. Purple fluorescence is not commonly associated with normal skin and is often linked to more serious skin concerns. Understanding these fluorescence responses is essential for estheticians in diagnosing and treating skin conditions effectively.
