Keloid scarring in acne. Close-up of the skin of a 24-year-old male patient with keloid scars caused by acne. Acne is a common skin disease characterised by scaly red skin,spots and pimples,which can leave scars. Keloid scars are a type of scar composed mainly of collagen. They are a result of an overgrowth of granulation tissue (collagen type 3) at the site of a healed skin injury,which is then slowly replaced by collagen type 1. Keloids are firm,rubbery lesions or shiny,fibrous nodules,and can vary from pink to flesh-coloured or red to dark brown in colour | |
