What characteristic defines skin that is considered oily?

Skin that is considered oily is primarily characterized by a shiny appearance. This shine is caused by an overproduction of sebum, which is the natural oil produced by sebaceous glands in the skin. When the skin produces excess sebum, it can create a glossy or oily sheen, especially on the forehead, nose, and chin, commonly referred to as the T-zone.

This shiny look is often accompanied by enlarged pores and a tendency to be more prone to acne and breakouts due to the accumulation of oil and bacteria on the skin's surface. Understanding this characteristic is important for skincare routines, as individuals with oily skin may need products that help control oil production while still providing moisture to prevent dryness.

The other options—dry to the touch, itchy sensation, and pale coloration—do not directly correlate with the characteristics of oily skin. In fact, dry skin is the opposite of oily skin, while itchy skin can be a sign of irritation or an allergic reaction, and pale coloration often relates to skin health rather than oiliness.
