Which characteristic signifies oily skin type?

Oily skin is primarily characterized by an excess production of sebum from the sebaceous glands, which leads to a shiny appearance on the surface of the skin. This overproduction often results in enlarged pores, as the excess oil can clog them, making them more noticeable. Individuals with oily skin may also experience a more pronounced texture due to the buildup of oil and dead skin cells, often leading to acne and other blemishes.

The option that describes shiny appearance and enlarged pores accurately encapsulates the primary characteristics of oily skin. This context is essential for estheticians and skincare professionals when recommending treatments or products suitable for clients with an oily skin type.
