Which skin condition is a common indicator of dehydration?

Oily skin
Hyperpigmentation
Flaky skin
Acne vulgaris

The correct answer is: Flaky skin

Flaky skin is a common indicator of dehydration because when the skin lacks sufficient moisture, it can lead to a dry and flaky appearance. Dehydration reduces the skin's ability to retain water, which can result in a compromised skin barrier and visible texture issues. This flakiness can be a sign that the skin is not receiving enough hydration, whether from internal sources, such as water intake, or external sources, such as moisturizing products. In contrast, oily skin is characterized by an overproduction of sebum, often not directly related to dehydration. Hyperpigmentation refers to dark patches on the skin that can occur due to various causes, such as sun exposure or hormonal changes, rather than hydration levels. Acne vulgaris is a form of skin condition that results from various factors, including hormonal changes and clogged pores, and is not typically a direct indicator of dehydration.
