What is oily skin?
Sebum, which is produced by the sebaceous glands situated below the surface of the skin, is the skin’s natural oil. Sebum production varies from person to person. Oily skin is characterised by excessive sebum production, especially at puberty and during the premenstrual phase, which makes the skin shiny. The oiliest area, and the one often prone to acne and blackheads, is the central panel, which runs from the forehead down to the chin. This area has a high concentration of sebaceous glands and the complexion may have a coarsely grained texture and be open-pored and sallow. It can sometimes be sensitive and susceptible to allergies, too.
