What factors predispose to keloid or hypertrophic scarring?
Keloid and hypertrophic scarring is more common in darker skin. Hypertrophic scarring is more common than keloid scarring. Increased skin tension or wound tension can also predispose to hypertrophic and keloid scarring. Keloids tend to develop more readily after puberty, and are more common in younger individuals rather than older individuals due to the greater tension of younger skin that predisposes to increased scarring. Darker parts of the skin are more predisposed to keloid or hypertrophic scarring, thus the palms and soles of feet are rare places for keloids to form.
