👉 Auto-pimples, also known as cystic acne or inflammatory acne, are a type of acne that forms when pores become clogged with dead skin cells, oil, and bacteria, leading to the formation of painful, inflamed cysts. These cysts occur when the hair follicle becomes blocked, causing pus and bacteria to accumulate, which triggers inflammation. The result is a painful, often red, and sometimes pus-filled bump beneath the skin's surface. Unlike regular pimples, which are usually smaller and less inflamed, cystic acne is more severe and can lead to scarring if not treated properly.
