What is an acne cyst?

Dr. Mehmet Oz, MD
Cardiology (Cardiovascular Disease)

Cysts are a type of inflammatory acne, the kind in which the skin around the pore becomes very inflamed, red, and swollen. Acne cysts are not like fluid-filled cysts found on other parts of the body. Acne cysts are large bacteria-and pus-filled pores that are deep under the skin.

These painful, purplish-red pimples may start small, but can swell to half an inch wide. People can develop one cyst, or many, anywhere on the neck, face, chest, back, and upper arms. The cysts sometimes break open, oozing and bleeding, often leaving scars. Acne cysts are considered an advanced form of acne and a dermatologist should be consulted for more information about treatment.
