A keloid is a growth of extra scar tissue. It occurs where the skin has healed after an injury.
A keloid, or keloid scar, is a kind of overgrown scar, or an overly aggressive healing response to a wound.
It's a type of thick, irregular scar that rises above the skin level and extends beyond the original wound boundaries.
Keloids can form after skin injuries from:
Ear or body piercing
Cuts from surgery or trauma
A keloid may be:
Flesh-colour, red, or pink
Located over the site of a wound or injury
Lumpy or ridged
Tender and itchy
Irritated from friction such as rubbing on clothing
A keloid will tan darker than the skin around it if exposed to sun during the first year after it forms. The darker colour may not go away.
