Get maderma for scars at walmart. It's about 11 bucks, but it really works!
Also, there's a product made by AcneFree for acne scars. It comes in a white and blue box and you can find it on the face wash aisle at walmart. It comes with a lotion for old acne areas and a moisturizer. I'd buy both and begin a daily regimen. I bought them both for my husband, and I can promise that they work. In 8 weeks if you use the maderma daily, your scar will not even exist!
