Since it is difficult to treat long standing, especially keloid-type scarring, the best approach is prevention.

• Clean the area early, removing debris and other material contaminating the wound. If it a gaping wound, go to a medical professional for closure, so eventual scarring is minimized.
• Apply an antibacterial ointment to promote the regrowth of skin cells, and use a semi-breathable dressing. More than a week’s delay in cell regrowth may cause a big scar to form.
• To lighten dark scars, bleaching products containing hydroxyquinone or exfoliants containing alpha-hydroxyacid (AHA) or glycolic acid may be used. Test for hypersensitivity first by first using small quantities over non-exposed areas. Be prepared to use it over an extended period of three to six months. Before buying the product, make sure there is a seal of approval by the Bureau of Food and Drug (BFAD) and buy only from licensed and known drugstores.
