What characterizes keloid scars?

Keloid scars are characterized by their tendency to extend beyond the original wound margins, which is a key distinguishing feature. Unlike typical scars, which remain confined within the boundaries of the initial injury, keloids grow in an overabundant manner due to an excess of collagen production during the healing process. This excessive growth leads to raised, often firm lesions on the skin that can vary in size and can continue to expand well beyond the original injury site. The appearance of keloids is often noticeable and can present a variety of colors, making them prominent compared to other types of scars. Understanding this growth pattern is crucial for proper diagnosis and treatment options for individuals with keloid scars.
