👉 Arc pimples, also known as cystic or nodular acne, are a severe form of acne characterized by large, painful, and often inflamed lesions. They occur when hair follicles become clogged with dead skin cells, oil, and bacteria, leading to the formation of pus-filled cysts beneath the skin's surface. These cysts can become infected, causing significant pain and swelling, and may leave behind scars if not treated promptly. Unlike regular pimples, arc pimples are deep-rooted and can be particularly challenging to treat due to their size and the complexity of the underlying inflammation.
