Vitamin E is great for scars! If you just get one of the pills and cut it open its an oil you can apply on the scars. tea tree oil is also an option though many people don't like the smell.
Get "Pure Vitamin E Skin Beauty Oil" at the cosmetics counter. Be sure it says "Pure". You can also use capsules by poking a hole with a pin and squeezing the oil out. Vitamin E has to soak in, so put it on when you can leave the skin bare for a while.
