What type of skin is typically characterized as oily?

Oily skin is typically characterized by an excess production of sebum, which often leads to a shiny appearance and can contribute to the development of acne. While “acne-prone skin” refers to skin that is prone to breakouts, it often coincides with oily skin, making it the most fitting choice for this question. Oily skin can lead to clogged pores and blackheads due to the surplus oil, frequently resulting in acne lesions.

The other options refer to different skin types that do not align with the characteristics of oily skin. Dry skin lacks sufficient oil and moisture, normal skin has a well-balanced mix of oil and moisture, and combination skin contains both oily and dry areas. Therefore, acne-prone skin is more directly associated with oily skin, making it the correct response.
