Retin-A micro can it help with indented face scar? (Photo)

I have a small indented scar on my face that is year and three months old. I was hit by some type of spider. Also, I'm almost 55 and concerned about aging skin. I did some laser treatments which helped some. Can retinA micro help or hurt? Some people say return A causes scarring? Nervous now after I got my prescription. Thanks for as my advice.
