Scars
A scar is a patch of skin that develops over an injury as part of our skin’s natural healing process. When a wound occurs, fibrous tissue replaces the normal tissue in the skin and thus it appears as a scar. There are many types of scars, each determined by the depth of the wound and tissue response towards the inflammation of skin.
