What grade of acne includes minor breakouts mostly consisting of open comedones?

Grade I acne is characterized by minor breakouts, primarily consisting of open comedones, which are also known as blackheads. This grade reflects a mild form of acne where there are few inflammatory lesions, and the skin may have some non-inflammatory lesions like open comedones. It is important to recognize that this level of acne typically does not involve significant redness, swelling, or the presence of deeper cysts, which are more prominent in higher grades of acne. Understanding the classification of acne helps in determining appropriate treatment options and management strategies. Grade I serves as the foundation of understanding how acne severity might progress if not managed properly.
