The body is using up water constantly. People need to replace the water they lose by drinking water and other fluids.
If people use more water than they take in, they can become dehydrated. Dehydration can affect all parts of the body, including the skin.
Dry skin and dehydrated skin are similar. However, although they can look the same, they are due to different factors.
When dry skin occurs, it means that the skin is not producing enough natural oils it needs to maintain itself. This can happen for a few reasons.
A person may have a skin condition, such as dermatitis or eczema. Frequent washing can also cause dry skin by stripping the oils present in the skin. Additionally, some people naturally have drier skin than others.
By contrast, dehydrated skin is a result of insufficient consumption of water.
Examining the other symptoms a person is experiencing can help healthcare professionals tell the difference between dry and dehydrated skin.
Mild dehydration is common. One of the symptoms of dehydration is dry skin patches.
The patches might be rough, scaly, or itchy. People may also have more noticeable fine lines in the skin or a dull complexion. They may also find that their skin is less elastic, or stretchy, than usual.
