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

Normal healthy skin appears blue/white under a Wood's lamp due to the way the skin's natural properties reflect UV light. The Wood's lamp, which emits ultraviolet light, is used in skincare to assess various skin conditions. Healthy skin generally shows a blue/white fluorescence, indicating well-hydrated skin and a lack of any significant underlying issues or infections.

Understanding this fluorescence is crucial for estheticians, as it helps them identify skin health and tailor treatments. Other colors observed under the lamp can indicate specific issues: for example, a green fluorescence may point to certain bacterial infections, while yellow can indicate the presence of oil or dead skin cells. This knowledge allows professionals to make informed decisions in skincare treatments based on the condition of the client's skin.
