Skin that looks oily, feels greasy to touch and is prone to blackheads and pimples is known as oily skin. Oily skin is caused by glands that produce too much sebum, resulting in skin that has a greasy slippery texture, appears shiny and frequently has large, clogged pores. This type of skin is prone to develop acne, a condition resulting from sebum trapped inside the skin. Oily skin usually shows up at puberty when the oil level shoots up due to hormonal changes. The oiliness of the skin can change from day to day, depending on the sun, the wind, time of the year, and the weather. Touching oily skin may sometimes leave a residue of oil on the fingertips.
As with any skin type, over-washing can strip the skin of its natural oils, so wash no more than twice a day with a cleanser designed to eliminate excess oils and lipids that block pores and create aggravating blemishes. Another mistake many make is thinking a moisturizer will only add to their oily skin worries. It is important to use a light, oil-free moisturizer to leave skin feeling hydrated without greasy residue.
