What skin condition involves excessive oil production and enlarged pores?

Acne is characterized by excessive oil production and the presence of enlarged pores. It is primarily associated with the overactivity of sebaceous glands, which produce sebum. This excess oil can clog hair follicles, leading to the formation of comedones (both open and closed), papules, pustules, and sometimes cysts. The enlarged pores are a direct consequence of the accumulation of oil, dead skin cells, and bacteria within the follicles, which can cause inflammation and result in the visible appearance of these pores.

In contrast, eczema is primarily a condition that involves inflammation and irritation of the skin without a direct correlation to excess oil production. Psoriasis is an autoimmune condition characterized by rapid skin cell turnover, leading to thick, scaly patches rather than enlarged pores or excess oil. Rosacea involves facial redness and visible blood vessels, often triggered by various environmental factors, but it does not involve increased oil production in the same manner as acne. Thus, the connection between excessive oil production, enlarged pores, and the presentation of acne makes it the correct choice in this context.
