Keloids are scars that appear higher or darker than your natural skin and grow larger than most. These scars can cause discomfort and stress, but they have the most impact when they develop in noticeable areas. If you are prone to keloid scarring, avoid piercings and other operations that may result in scar formation. If you are unable to avoid a surgery or injury that may result in a facial scar, a healthcare practitioner can offer treatment choices to help reduce the appearance of keloids as well as other resources to help you cope.
