Pimples, pustules, and cysts are typical of which type of acne?

The correct choice describes inflamed acne, characterized by pimples, pustules, and cysts. In this type of acne, there is significant inflammation, which often leads to the formation of red, swollen lesions filled with pus or deep-seated lumps beneath the skin. This inflammation occurs when hair follicles become clogged with oil and dead skin cells, allowing bacteria to multiply, causing further irritation and swelling in the surrounding tissue.

Noninflamed acne refers to closed or open comedones, such as blackheads and whiteheads, which do not exhibit the swelling or redness typical of inflamed acne. Comedonal acne specifically consists of these non-inflamed forms, while blackhead acne is a term that generally refers to open comedones alone. Thus, these other acne types do not present with the inflamed characteristics involving pustules and cysts that inflamed acne does.
