What symptom reports an increased level of skin oiliness?

The symptom indicating an increased level of skin oiliness is greasy skin. This condition reflects an overproduction of sebum, the natural oil produced by sebaceous glands in the skin. When the sebaceous glands are hyperactive, they release more oil than usual, leading to a shiny or slick appearance on the skin's surface. This excess oil can also contribute to various skin issues, such as acne.

In contrast, dryness refers to a lack of moisture and oil in the skin, which is the opposite condition to greasy skin. Itching can result from various skin problems but does not specifically indicate oiliness. Flaking typically occurs when the skin is dry or irritated, further underscoring the difference between it and the condition of having an oily or greasy appearance.
