cystic acne

cystic acne A localized infection (abscess) that is formed when oil ducts become clogged and infected. Cystic acne is most common in the teenage years. Treatment includes avoiding irritants on the face, including many cleansers and cosmetics, and in some severe cases, use of steroid or antibiotic medication.
