Oily skin is shiny, thick and dull colored. Often a chronically oily skin has coarse pores and pimples and other embarrassing blemishes. It is prone to blackheads. In this type of skin, the oil producing sebaceous glands are overactive and produce more oil than is needed. The oil oozes and gives the skin a greasy shine. The pores are enlarged and the skin has a coarse look.
