Keloids are raised scars that form when the body produces too much collagen during the healing process. They can develop after injuries, surgeries, or even minor skin irritations. Keloids often appear shiny and can vary in color, sometimes being darker than the surrounding skin. They can occur anywhere on the body but are most common on the chest, shoulders, and earlobes. These scars can be itchy or painful, and while they are not harmful, they may cause cosmetic concerns for some individuals. Treatments for keloids include steroid injections, surgery, and laser therapy, but they can sometimes recur after treatment.
