Keloid scar treatment. Close-up of a silicon gel patch being used to help improve the appearance of a keloid scar on the arm of a 61-year-old male patient. A keloid scar is typically raised above the level of the surrounding skin. It is composed mainly of collagen as a result of an overgrowth of granulation tissue. Silicon is commonly used to help prevent scar formation and to improve the appearance of existing scars.
