A keloid scar is characterized specifically by its sharply elevated and irregularly shaped appearance. Keloids form as a result of an overproduction of collagen during the healing process after an injury to the skin. This excessive collagen leads to the scar extending beyond the original boundaries of the wound, resulting in a raised, often shiny, and uneven texture.

The irregular shape can vary from one individual to another, as keloids can grow in various directions and may even change over time. They are usually darker than the surrounding skin and can be itchy or painful. The characteristics of keloids differentiate them from other types of scars, such as hypertrophic scars, which may also be raised but generally remain within the confines of the original injury site. In contrast, the other options describe alternative scar types: smooth and flat scars are typical of normal healing, while dark and depressed or light and faded scars suggest different healing processes or scar types altogether.
