What is the most severe form of acne?

Cystic acne represents the most severe form of acne due to its deep, painful, and often inflamed nodules that form beneath the skin's surface. Unlike other types of acne, cystic acne is characterized by its large, fluid-filled cysts that can lead to significant scarring and require more intensive treatment options. This type of acne is often caused by hormonal fluctuations and can be exacerbated by factors such as stress, diet, and genetics.

In contrast, hormonal acne typically appears in cycles, usually affecting the lower part of the face. Whiteheads and blackheads are forms of comedonal acne and are generally less severe as they do not involve the deep inflammation or pustules characteristic of cystic acne. While all these types can be problematic and distressing, cystic acne is specifically noted for its severity and the challenges it presents in terms of management and potential for scarring.
