Which term describes a skin condition resulting from the presence of excess oil on the skin that can lead to acne?

The term that best describes a skin condition resulting from the presence of excess oil on the skin, which can lead to acne, is comedones. Comedones represent clogged hair follicles, which occur when oil (sebum) and dead skin cells accumulate in the pores. This build-up can result in the formation of blackheads or whiteheads, both of which are forms of acne.

While seborrheic dermatitis is related to oil production and the skin’s appearance, it is primarily characterized by red, flaky patches with oily scales and does not directly describe the clogged pores that lead to acne. Urticaria refers to hives, which are raised welts resulting from an allergic reaction, and angioedema is a deeper swelling of the skin, often associated with allergic responses, neither of which are associated with excess oil specifically leading to acne. Thus, comedones are directly tied to the underlying mechanism of acne due to excess oil on the skin.
