When the skin is injured, fibrous tissue called scar tissue forms over it to repair and protect the wound. Keloids are smooth, hard growths that emerge when extra scar tissue grows. Keloids can grow to be several times the original wound size. They’re most commonly found on the chest, shoulders, earlobes, and cheeks. Keloids, on the other hand, can manifest themselves in any part of the body. Keloids aren’t harmful to your health, but they can be unsightly.
Although keloid scars are itchy, they rarely pose a health risk. You may feel uncomfortable, sore, or irritated as a result of your clothing or other sources of friction. Keloids are usually more of an aesthetic problem than a health problem. If the keloid is really large or in a highly visible position, such as on an earlobe or the face, you may feel self-conscious.
