It’s the most severe type of acne, but it usually improves with age.

Cystic acne can look like large, pus-filled boils on the skin. It can also be painful to the touch. If these boils rupture, they can cause scarring.

Cystic acne most commonly occurs on your face, chest, neck, back, and arms.

If you believe you may have cystic acne, a dermatologist can prescribe medications to help treat it.

A cyst can appear as a bump on your skin. These can vary in size from small, pimple-sized lumps to much larger, more obvious growths.

Some cysts grow deep inside your body where you can’t feel them. But they may cause or be related to other symptoms.
