Which skin condition is characterized by excessive oiliness and blemishes?

The condition characterized by excessive oiliness and blemishes is acne. Acne occurs when hair follicles become clogged with oil and dead skin cells, leading to the development of pimples, blackheads, and cysts. This condition is particularly common during adolescence due to hormonal changes that increase sebum production, but it can affect individuals of all ages.

Acne is also associated with inflammation and bacterial growth, which can exacerbate the appearance of blemishes and lead to scarring if not treated properly. It's important to note that while other skin conditions may involve oiliness or irritation, acne specifically manifests through the combination of excess oil, clogged pores, and the formation of various types of blemishes. Understanding the distinct characteristics of acne helps in recognizing its treatment options and preventing future breakouts effectively.
