👉 Ass pimples, also known as cystic acne, are a severe form of acne characterized by large, painful, and inflamed lumps beneath the skin's surface. These pimples form when hair follicles become clogged with dead skin cells, oil, and bacteria, leading to the formation of a pimple. When the follicle becomes infected, it can expand and become inflamed, causing pus to accumulate and resulting in a cystic acne lesion. These pimples are typically deep, painful, and can leave behind scarring if not treated properly. They often require medical intervention, including topical treatments, oral medications, or even surgical procedures, to effectively reduce inflammation and prevent scarring.
