Hypertrophic scars are a type of thick, red scar that is raised from the surface of the skin. They are similar to keloid scars, except they do not extend outside the area of the original wound, like keloid scars do. Hypertrophic scars can also be very itchy. Their appearance tends to improve naturally over time and then can flatten out and become less uncomfortable.
Hypertrophic scars form when there is an excessive production of collagen during wound healing. They tend to occur after a traumatic injury that has penetrated into the deeper layers of the skin. Body piercing can result in hypertrophic scars. There is also a genetic link to hypertrophic scarring.
You can get a hypertrophic scar anywhere there has been a traumatic injury.
Anyone can get hypertrophic scarring.
