What causes keloid scarring?
Keloid scarring occurs after damage to the skin in susceptible individuals. This injury can be minor such as acne, an insect bite or body piercing. Keloid scars behave like benign growths, but unlike other scars, they extend beyond the original injury. Apart from their unsightly appearance a study in 2004 by Lee and colleagues, published in the “Journal of the American Academy of Dermatology,” showed that the majority of patients with a keloid suffered pain and/or itching. Keloids will not regress or improve over time and have a high recurrence rate after surgery.
