Keloid Acne Scars

Keloid or hypertropic scars, are less common and appear to be hereditary. They are found primarily in African-American, Asian and Latino patients.  Keloid scarring occurs when the skin responds to injury by producing an excess of collagen.  The excess collagen forms into lumpy fibrous masses that are seen most frequently along the jaw line or on the back and chest. These scars appear firm and shiny, and may persist for years.  They may also extend beyond the original wound and often appear darker or redder than the surrounding skin.  Keloids may develop months after injury and may enlarge without treatment.
