(Red or Dark and Raised)
Like hypertrophic scars, keloids are the result of an imbalance in the production of collagen in a healing wound. Unlike hypertrophic scars, keloids grow beyond the boundary of the original wound. They can continue to grow indefinitely. They may be itchy or painful and may not improve in appearance over time.
Keloid scars can result from any type of injury to the skin, including scratches, injections, insect bites and tattoos. Anybody can get a keloid scar and they can occur anywhere on the body. However, the young and people with darker skin are more prone to this type of scarring and they are more common on certain parts of the body e.g. ears, chest, shoulders and back.
As with hypertrophic scarring, people who have developed one keloid scar are likely to be prone to this condition in the future and should alert their doctor or surgeon if they are likely to need injections or to have any form of surgery.
