What is a common characteristic of oily skin?

Oily skin is characterized by an overproduction of sebum from the sebaceous glands, which leads to a shiny appearance on the surface of the skin. This shine is often most noticeable on the forehead, nose, and chin—areas commonly referred to as the T-zone. The excess oil can give the skin a reflective quality, making it appear slick or greasy, especially throughout the day.

This characteristic also contributes to other issues that may accompany oily skin, such as enlarged pores and a higher propensity for acne and blemishes. The shine varies among individuals, with some experiencing a slight glow and others having a pronounced glossiness. Understanding the common traits of oily skin helps skincare specialists recommend appropriate products and treatments, such as oil-free moisturizers and non-comedogenic formulations, to manage the skin's condition effectively.
