👉 Announcement pimples, also known as inflammatory acne nodules or cysts, are a severe form of acne characterized by deep, painful lumps beneath the skin's surface. Unlike regular pimples, which appear as red bumps or whiteheads, these pimples result from a more intense inflammatory response, often triggered by bacterial infection and excessive sebum production. The deep inflammation causes the skin to pull away from the underlying tissue, forming a hard, often red or brown nodule beneath the skin's surface. These pimples can be extremely painful and may lead to scarring if not treated promptly and effectively.
