Here's a breakdown:
* Collagen: Collagen is a fibrous protein that provides structure and support to various tissues in the body, including skin.
* Normal Healing: When skin is injured, the body produces collagen to repair the damage. This process is usually controlled and results in a scar that's similar in color and texture to the surrounding skin.
* Keloid Formation: In some cases, the body produces an excessive amount of collagen during healing. This excess collagen builds up in the wound area, forming a raised, firm scar that extends beyond the original injury. This abnormal scar is known as a keloid.
Keloids are not harmful, but they can be cosmetically displeasing and sometimes itchy or painful. They are more common in people with darker skin tones.
