What condition is characterized by too much oil on the skin?

The condition characterized by too much oil on the skin is acne. Acne occurs when sebaceous glands produce excess sebum, which can clog hair follicles and lead to the formation of pimples, cysts, or other lesions on the skin. This overproduction of oil is often influenced by various factors including hormonal changes, diet, and skin type. Acne is most commonly associated with the adolescent years, but it can affect individuals of any age.

In contrast, aging refers to the natural process of skin changing over time, typically leading to dryness and loss of elasticity rather than oiliness. Dry skin is the result of insufficient moisture and is not associated with excess oil production. Psoriasis is an autoimmune condition that leads to rapid skin cell turnover, causing thick, red, scaly patches, and while it can be confused with skin that appears oily, it is fundamentally different from acne in its cause and presentation.
