What color will thin or dehydrated skin appear as under a Wood's lamp?

1. Light blue

2. Light violet

3. Green

4. Pink

The correct answer is: Light violet

Under a Wood's lamp, thin or dehydrated skin typically appears light violet. This coloration occurs because the Wood's lamp emits ultraviolet light, which causes certain skin conditions and hydration levels to become more visible. When skin is dehydrated, it can exhibit a bluish or violet hue due to the reduction in moisture content, which affects how light interacts with the skin's layers. Light violet signifies a degree of dehydration and helps estheticians identify the need for hydration treatments or formulations. Understanding this aspect is crucial for the proper assessment and care of clients, allowing for tailored skincare regimens that address specific skin concerns. In contrast, light blue often indicates thicker skin or normal hydration levels, green typically reflects the presence of bacteria or other infections, and pink usually suggests good skin health and hydration. Being able to distinguish between these colors helps professionals provide more effective skincare solutions.
