Oily skin is characterized by an overproduction of sebum, which is an oily substance produced by the sebaceous glands. This excessive oil can lead to a shiny appearance on the skin's surface. Additionally, oily skin often has visible pores, which can appear enlarged due to the buildup of oil and dead skin cells. The presence of shine and visible pores are hallmark features that distinguish oily skin from the other skin types.

Dry skin tends to lack moisture and may appear dull without the shine that comes from excess oil. Combination skin can have areas of both oiliness and dryness, typically showing shine in the T-zone while remaining dry in other areas. Normal skin maintains a balanced moisture level and does not typically exhibit significant shine or enlarged pores. Thus, the characteristics associated with oily skin clearly align with the description provided in the question.
