A keloid is a bump or nodule that forms on the body at the point of an injury or open wound on the skin. Keloids are usually red or deep purple in color.
Keloids are more often seen in those with a darker skin tone, while hypertrophic scars are found in those of all skin types. They equally affect both genders.
The keloid will start forming from 3 months to a year after original skin damage. They’re most common on the breast bone, shoulder, earlobe, and cheek. You will probably first notice scar tissue growing past the borders of the original damage. It can become tender, itchy, painful, or produce a burning sensation.
Keloids are sometimes confused with hypertrophic scars. They are more common than keloids and do not get quite as large. Usually, keloids and hypertrophic scars are not harmful.
