Keloid Scar

Keloid scars are lumpy, red raised scars that have grown bigger than the original wound that is healing. They are more common in people with African, Southern Indian and Afro-Caribbean heritage. They are completely harmless but can cause distress and embarrassment. Keloid scars are incredibly difficult to treat and treatment is not always successful.
Why people get keloid scarring is not exactly clear, however, they form when there is an overgrowth of scar tissue during wound healing and seem to have a genetic link. Keloid scarring doesn't necessarily occur just with serious cuts or wounds, it can form even with minor cuts or abrasions, if you are predisposed to them.
You can get a keloid scar anywhere on the skin where there has been a wound.
Keloid scars tend to have a genetic link so if someone in your family has them you may also be prone to them. They are also far more prevalent in people with darker skin types such as African, Afro-Caribbean and Southern Indian.
