What Causes Scars?
Scars are a natural part of the healing process after an injury or surgery.
When the dermis - the second layer of the skin - is damaged, collagen protein is formed to repair the area, creating a scar.
Your scar's appearance will depend on its location and size, as well as the depth of the original injury. It will also depend on your age, gender, ethnicity, and genes.
Scars from a broken arm, appendix removal, and other surgeries are a reminder of your injury, but also that you've healed. If the way your keloid or hypertropic scars look bothers you, further treatments can help. Use products like those on the right to minimize the appearance of most surgical scars.
