What characterizes a keloid scar?

A keloid scar is characterized by its irregular shape and tendency to grow progressively larger over time. Keloids are a type of raised scar that forms when the body produces too much collagen during the healing process. This results in a thick, fibrous tissue that extends beyond the original wound site. Unlike other types of scars, keloids can continue to grow well after the initial injury has healed, which is why their irregularity and enlargement are key identifying features.

While other types of scars may exhibit different characteristics—such as being flat and smooth, having a soft texture, or causing discomfort—these descriptions do not apply to keloid scars. Keloids are often firm and can extend beyond the boundaries of the original injury, making the correct identification of their characteristics crucial for proper diagnosis and treatment.
