Scars occur when damage is caused through to the deepest layer of the skin. The type of scar will depend on the nature and location of the injury.
Some insults can result in a keloid being formed. This can be visibly thick, red and sometimes itchy and can grow larger with time. Injections of anti-inflammatory medications or some forms of laser treatment for this type of scar may help flatten and reduce the size and colour of the scar, as well as itchiness or pain.
The appearance of some scars may be minimised with laser treatment, but depends on their colour, type and location. New scars usually respond better than mature scars as remodelling is still occurring naturally within the scar and this can then be modified by the laser.
