Which of the following is a common sign of skin dehydration?

Flaking and tightness are common indicators of skin dehydration. When the skin lacks adequate moisture, it can become dry, leading to a flaky appearance as the top layer of skin loses its ability to retain moisture. Additionally, the skin often feels taut or tight due to the diminished water content. This contrasts with other conditions; for instance, increased oiliness or an oily sheen typically suggest overproduction of oil rather than dehydration. In the case of dehydrated skin, the oil glands may produce more sebum in an effort to compensate for the lack of moisture, but such symptoms do not directly indicate dehydration itself. Therefore, flaking and tightness serve as clear signs that the skin requires hydration and care.
