Which type of acne is characterized by deep cysts and nodules?

Cystic acne is distinguished by the presence of deep-seated cysts and nodules, which typically develop beneath the skin's surface. This form of acne is often inflammatory and can cause significant discomfort, as well as potential scarring. The cysts are often filled with pus and can be painful to the touch, representing a more severe type of acne that goes beyond superficial lesions.

Comedonal acne generally involves non-inflammatory lesions like blackheads and whiteheads, which do not penetrate deeply into the skin. Papular acne presents as small, raised bumps that are typically red and inflamed but do not form cysts. Hormonal acne is influenced by hormonal fluctuations and often presents as breakouts along the jawline and chin, but it may not necessarily manifest as deep cysts or nodules. Thus, cystic acne is specifically defined by the deep, painful bumps typical of this type, making it the correct identification for this type of acne.
