Dehydrated skin is a skin condition that occurs when there’s a lack of water, not oil in the skin. Dehydrated skin feels tight, looks dull, and tends to exaggerate the signs of ageing like wrinkles and dark circles beneath the eyes. Similar to dry skin, redness and inflammation are common signs of dehydration. But unlike dry skin, dehydrated skin is characterised by a lack of water not oil, meaning even oily skin types can becomes dehydrated. Classic symptoms of dehydrated skin include flaky skin, increased skin sensitivity, and dull skin which make fine lines and wrinkles more apparent.
