What are hypertrophic scars?

Hypertrophic scars are characterized as raised scars that remain confined to the original boundaries of the wound. They occur due to an overproduction of collagen during the healing process, which leads to a thickening of the skin tissue at the site of injury. Unlike keloid scars, which extend beyond the initial injury site, hypertrophic scars are limited to the area of the wound and usually become less prominent over time, although they can remain raised. This specific characteristic is what distinguishes hypertrophic scars from other types of scars.

In addition to their raised appearance, hypertrophic scars often are red or darker in color initially, which may fade over time. They may also be itchy or uncomfortable but generally do not pose the same risks associated with keloids, such as significant cosmetic concern, pain, or functional impairment. Understanding the nature of hypertrophic scars is crucial for providing appropriate management and treatment options post-surgery or injury.
