What is the primary characteristic of dry skin?

The primary characteristic of dry skin is a lack of moisture and sebum production. When the skin is classified as dry, it typically means that the sebaceous glands are not producing enough oil to maintain hydration levels. This leads to a decrease in the skin’s barrier function, making it more susceptible to moisture loss, which can result in a rough, flaky texture and a feeling of tightness.

In dry skin, the insufficiency of natural oils decreases the skin’s ability to retain water, making it appear dull and less elastic. This condition may also be influenced by environmental factors such as low humidity, harsh weather, or prolonged exposure to hot water during baths or showers. Consequently, understanding that dry skin is fundamentally due to a lack of moisture and sebum is crucial for implementing appropriate skincare strategies that aim to restore hydration and barrier function.
