What is a keloid?
A keloid is a scar that heals in an overly aggressive manner, becoming thick and raised from excessive collagen production and is sometimes referred to as a hypertrophic scar. They may appear pinker or darker than the surrounding skin and if close to a joint, may limit movement.
Unlike normal scarring, a keloid can arise from minor trauma or even spontaneously.
Keloids can begin to appear from a few weeks to many months after the trauma or surgery and continue to grow for months or years, extending beyond the extent of the original wound.
A tendency to form keloids is more common in people with darker skin and there may be a family history.
