acne scars

I used to get acne on my back (cleared up with having a baby) and am now left with some small scars that make me not want to wear backless tops : Also every single month with AF I get a spot in the exact same area around my mouth and each time they leave a small scar. It seems like the older I get the worse my skin does at healing itself. Anything I can do to help these fade? Is it too late for vit e? (some of them are years old). TIA.
