Which characteristic is most commonly associated with oily skin rather than dry skin?

The characteristic most commonly associated with oily skin is a shiny appearance. Oily skin tends to produce excess sebum, which can create a reflective surface, making the skin look shiny. This is particularly noticeable in areas such as the forehead, nose, and chin, often referred to as the T-zone.

In contrast, dry skin typically has a flaky texture due to a lack of moisture and can feel tight because of insufficient sebum production. Additionally, dry skin may exhibit roughness as it lacks the natural oils that keep skin smooth and supple. These features distinguish dry skin from oily skin, highlighting the unique properties of each skin type.
