What type of skin condition is characterized by excessive oil production?

Oily skin is characterized by excessive oil production due to overactive sebaceous glands. This condition leads to a shiny appearance, enlarged pores, and often an increased likelihood of acne and blemishes because the excess oil can trap dirt and bacteria on the skin’s surface. Oily skin typically requires specific skincare products to help manage sebum production and maintain a balanced complexion.

In contrast, dry skin lacks moisture and can feel tight or rough, while combination skin exhibits characteristics of both oily and dry areas on the face. Sensitive skin is often reactive and can be easily irritated but isn’t defined by oil production. Thus, the defining trait of oily skin makes it the correct answer for this question.
