Hypertrophic scars occur when the body overproduces collagen, which causes the scar to be raised above the surrounding skin. Hypertrophic scars take the form of a red raised lump on the skin. Keloid scars are a more serious form of scarring, because they can carry on growing indefinitely into a large, tumorous (although benign) neoplasm. Hypertrophic scars are often distinguished from keloid scars by their lack of growth outside the original wound area, but this commonly taught distinction can lead to confusion. All keloid scars are hypertrophicbut "only a small percentage of large scars" are keloid. Differences exist between keloid scars and hypertrophic scars. Keloid scars can occur on anyone, but they are most common in dark-skinned people. Keloid scars can be caused by surgery, an accident, by acne or, sometimes, from body piercings. In some people, keloid scars form spontaneously. Although they can be a cosmetic problem, keloid scars are only inert masses of collagen and therefore completely harmless and non-cancerous. However, they can be itchy or painful in some individuals. They tend to be most common on the shoulders and chest.
The Hypertrophic scar like others is also caused by the lack of healthy collagen. Collagen Induction Therapy may be used on most hypertrophic scars (not keloid scars) so that the skin affected will produce healthy collagen thus repairing itself to a state that has the look and feel of the skin around it.
