Which characteristic is true of oily skin?

Oily skin is characterized by an overproduction of sebum, the natural oil produced by the sebaceous glands. This excess oil can lead to a shiny appearance on the skin, especially in the T-zone area, which encompasses the forehead, nose, and chin. Enlarged pores are also a common feature of oily skin, as the excess oil can clog pores, making them appear larger. This characteristic can lead to various skin concerns, including acne and blackheads.

The other options do not accurately represent the nature of oily skin. Flakiness is typically associated with dry skin, which has insufficient oil production. Dry skin tends to be rough and may experience peeling or visible flakes. If skin lacks adequate moisture, it will not exhibit the shine characteristic of oily skin. Saying that oily skin is always dry contradicts its fundamental definition, as oily skin is, by nature, moist due to the excess sebum. The claim that oily skin has a consistent texture is misleading, as it can often result in varying textures, including rough patches due to clogged pores or acne, which differ from the smoothness characteristic of other skin types.
