Girl those aren't scars it's hyperpigmentation as was stated above. Nothing but time will entirely heal them there's no quick fix product, and you can trust me on that since I've suffered with acne for a good amount of time.
When I was still struggling with my acne my Dermo swore that retina helps the fading process however you'd need to go to a Dermo to get it.
