What Causes Oily Skin?
Oily skin is exactly that. An oily face is the result of an abundance of oil on your skin, especially in your “T-zone,” which is the area across your forehead and down the bridge of your nose, including your chin. Simply put, your sebaceous glands (the glands that produce the oil your skin needs) are hyperactive, giving your skin too much of what normally is a good thing. Because of all that extra oil, your skin can feel greasy, look shiny, and be more susceptible to breakouts or acne.
The triggers of oily skin and an oily face vary, from genetics and diet to hormones and cosmetics. The result is overactive, oil-producing glands.
