What skin condition involves excessive oiliness and the presence of comedones?

The condition that involves excessive oiliness and the presence of comedones is acne. Acne is characterized by the overproduction of sebum from the sebaceous glands, which can lead to clogged pores. Comedones, which are the common term for blackheads and whiteheads, occur as a result of this clogging, where dead skin cells and excess oil mix. The increased oiliness can also create an environment conducive to bacterial growth, further exacerbating the condition. This makes acne distinct from conditions like dermatitis, which is mainly inflammatory and characterized by symptoms like redness and irritation, or psoriasis, which is a chronic autoimmune condition that results in thick, scaly patches on the skin. Hyperpigmentation, on the other hand, refers to darkened areas of skin due to excess melanin and does not inherently involve oiliness or comedones.
