The hard ball in a pimple is a comedone, a type of plug that forms in a hair follicle when oil, dead skin cells, and bacteria build up.
This plug can be either open (blackhead) or closed (whitehead).
Blackheads appear black because the plug is exposed to air and oxidizes.
Whiteheads are covered by a thin layer of skin, giving them a white appearance.
Pimples form when the comedone becomes inflamed, usually due to bacteria.
Inflammation causes redness, swelling, and pain.
Treatment for pimples typically involves over-the-counter or prescription medications to reduce inflammation and kill bacteria.
Prevention includes keeping skin clean, avoiding touching the face, and using non-comedogenic skincare products.
