Types of Scars
Normal fine-line scars
A minor wound, like a cut, will usually heal to leave a raised line. They will gradually fade and flatten over time; however, the scar will not disappear completely, and you'll be left with a visible mark or line.
This type of scar keeps growing, even after the wound has healed. It is due to the overgrowth of tissue when too much collagen is produced at the site of a wound.
These scars are the result of excess collagen being produced at the site of a wound.
Pitted or sunken scars
Some scars caused by skin conditions, such as acne, can have a sunken appearance.
Scar contractures are often caused by burns. They happen when the skin "shrinks", leading to tightness and a restriction in movement.
Acne causes pitted scars and skin discolouration's.
