What to do to cure light scarring?

Reduce not remove : You can try maderma, silicone sheets, scarzone and remember to prevent the scar from getting any worse by avoiding direct sunlight, smoking etc... You may be able to lessen the appearance, however, probably not remove the scar. Sometimes a scar revision can remove an old large scar and leave a more tolerable smaller one.

Mederma: Mederma or other scar reducing creams. Scar-guard, etc.

Improvement of scars: Scars can be secondary to accidents, burns or surgery. These behave differently and if the wounds get infected then there is another variable that will impact scarring.
