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

The presence of dehydrated skin can be identified using a Wood's lamp, which emits ultraviolet light that causes certain substances in the skin to fluoresce in specific colors. In this case, dehydrated skin appears as violet under the Wood's lamp. This color indicates a lack of moisture and hydration in the skin when observed, as the condition creates distinct fluorescence values.

The other colors associated with different skin conditions can lead to confusion, but in this specific scenario, it is the violet glow that distinctly signals dehydration, serving as a diagnostic tool for practitioners assessing skin health. Understanding the implications of this reading is critical for developing appropriate treatments for skin hydration and overall care.
