What condition is a characteristic of Grade 4 acne?

Grade 4 acne is classified as the most severe form of acne, and the presence of cysts is a defining characteristic. Cysts are deep, painful, pus-filled lumps that can occur when severe acne leads to the blocking of pores, inflaming the deeper layers of the skin. This inflammation can result in significant tissue damage and often leaves scars after healing.

In lower grades of acne, like Grade 1 or Grade 2, minor breakouts, closed comedones, and pustules may be observed, but they do not present with the extent and severity of cystic formations seen in Grade 4. Understanding the characteristics of various grades of acne helps in determining the appropriate treatment and management of the condition. Thus, recognizing that cysts are indicative of Grade 4 acne is crucial for estheticians and skincare professionals in diagnosing and formulating care plans for clients experiencing severe acne issues.
