What best describes Grade 3 acne?

Grade 3 acne is characterized as moderately severe and typically presents with inflamed papules and occasional cysts. This form of acne shows a significant increase in inflammation and the formation of nodules, which can be painful and may lead to scarring if not treated properly. The presence of these inflamed lesions indicates that the acne is beyond a mild or moderate level, where factors like hormonal changes, bacteria, and excess oil production are contributing to the severity of the condition.

In the context of acne classification, mild acne would primarily include scattered comedones with little to no inflammation. Moderate acne generally involves more closed comedones without the level of systemic involvement that is characteristic of Grade 3. Severe acne, on the other hand, would consist of widespread pustules and could include cystic lesions that cover a large portion of the skin, indicating a much more serious condition than just moderate severity. Hence, the description of Grade 3 acne effectively captures the balance of inflamed lesions and the potential for cystic formations, distinguishing it clearly from other grades of acne.
