You may be able to prevent long-lasting scarring by being proactive about a skin injury. Doctors typically recommend keeping the injured skin area moist and suggest Aquaphor or a petroleum based ointment. This is followed by Vitamin E oil that is lightly massaged once the scar is about three weeks old.
A scar area should get smaller and may need a full 10-12 months before it is completely healed. During that time doctors stress that it's important to protect it from the sun and its damaging UV rays. Use a sunscreen of at least SPF 30 even if you're not in the direct sun.
