Cystic acne is a severe form of acne characterized by large, painful, and inflamed cysts beneath the skin. It occurs when hair follicles become clogged with excess oil, dead skin cells, and bacteria, leading to deep, swollen lesions. This type of acne often affects the face, back, and shoulders and can result in scarring if not treated properly. Treatment for cystic acne typically involves medications such as topical retinoids, antibiotics, or isotretinoin. In some cases, dermatologists may recommend procedures like drainage or corticosteroid injections to reduce inflammation. Early intervention is crucial to minimize the risk of long-term skin damage.
