How does dehydration commonly affect the skin?

It can lead to increased oil production
It can result in dryness and flakiness
It enhances skin elasticity
It usually causes skin redness

The correct answer is: It can result in dryness and flakiness

Dehydration commonly affects the skin by resulting in dryness and flakiness. This occurs because when the body is dehydrated, there is a lack of water in the skin, which disrupts its ability to maintain moisture. The outer layer of the skin becomes less effective at retaining water, leading to a parched appearance and a rough texture. This dryness can also contribute to irritation and increased sensitivity, as the skin’s barrier function is compromised. Flakiness is a visible sign of this condition, as the natural shedding of skin cells becomes more pronounced when the skin lacks hydration. Maintaining proper hydration is essential for healthy skin, as it supports its natural moisture balance and overall appearance.
