What is a keloid?
Not everyone who gets a scar will develop a keloid. If you have keloid-prone skin, however, anything that can cause a scar may lead to a keloid. This includes a cut, burn, or severe acne. Some people see a keloid after they pierce their ears or get a tattoo. A keloid can also form as chickenpox clear. Sometimes, a surgical scar becomes a keloid.A keloid (key-loid) is a type of raised scar. Unlike other raised scars, keloids grow much larger than the wound that caused the scar.
In very rare cases, keloids form when people do not injure their skin. These are called “spontaneous keloids.”
A keloid usually takes time to appear. After an injury, months can pass before this scar appears. A keloid can also form more quickly.
Once it begins, a keloid can enlarge slowly for months or years.
