What color indicates dehydrated skin when viewed under a Wood's lamp?

When dehydrated skin is viewed under a Wood's lamp, it typically appears as violet or blue-violet in color. This hue results from the lamp's ability to highlight changes in the skin's hydration levels. Dehydration in the skin can affect how it reflects light, and under the specific wavelengths emitted by the Wood's lamp, the characteristics of dehydrated skin are brought into focus.

The violet color indicates that there is a lack of moisture in the stratum corneum (the outermost layer of skin). Understanding this aspect of skin examination is crucial for skincare specialists, as it helps in identifying and addressing hydration issues, thus guiding treatment plans for clients. Proper hydration is essential for maintaining skin barrier function, preventing premature aging, and promoting overall skin health.
