Scarring is a natural part of the healing process after an injury. Its appearance and its treatment depend on multiple factors. The depth and size of the wound or cut and the location of the injury matter. So do your age, genes, sex, and ethnicity.
There are several different types of scars including:
These scars are the result of an overly aggressive healing process. They extend beyond the original injury. Over time, a keloid scar may hamper movement.
If your skin has been burned, you may have a contracture scar. These scars tighten skin, which can impair your ability to move. Contracture scars may also go deeper, affecting muscles and nerves.
These are raised, red scars that are similar to keloids but do not go beyond the boundary of the injury.
If you've had severe acne, you probably have the scars to prove it. There are many types of acne scars, ranging from deep pits to scars that are angular or wavelike in appearance.
