Scarring does more than damage the appearance of the skin; it can also damage one's sense of well-being and self-esteem. Depressed or raised (hypertrophic) scars can be a result of acne, trauma or surgical procedure. Scar formation is a natural result of the healing process after injury, and various factors determine how well one's skin heals ( to minimize scarring ). While the degree of inflammation or trauma will impact the scar's characteristics, the location of the scar, genetics and ethnicity may affect what the scar looks like.
