Under a woods lamp, what color indicates dry skin?

Under a woods lamp, dry skin typically appears purple. This coloration indicates the presence of dehydration within the skin, often showing as a darker hue that signifies a lack of moisture. The woods lamp emits a specific type of ultraviolet light that enhances the visual differentiation of various skin conditions, enabling the esthetician to assess the skin's health more accurately.

In the context of skin analysis, each color reflects specific skin conditions or concerns. For instance, pink can indicate normal skin hydration levels, blue generally suggests the presence of bacteria or oil, and yellow could signify oily skin or the presence of certain types of pigmentation. Understanding these different color indicators helps estheticians tailor their treatments effectively, ensuring that each client's skin care regimen is appropriate for their unique needs.
