How do keloid or hypertrophic scars form?
If too much collagen is laid down in a haphazard manner or the normal process of collagen remodeling doesn’t occur, then a hypertrophic or a keloid scar forms. In general, those who are older with thinner, fair skin tend to heal with less chance of scarring than a younger person with thicker, darker skin. Younger people with thick skin tend to have robust collagen-producing cells that respond strongly to an injury by creating an abundance of collagen.
