How can I get rid of this old dark scars? (photos)

I got this scars from an insect bites since I was kid. I was not bothered about this before until I reach adolescence. I lost self-esteem because of this. I only wear long skirt that can cover down to my ankles. my ankles were also dark. I cant wear jeans because of religious matters. i feel like i had the worst legs ever. all i just wish was to wear a midi skirt without this scars. please help me. I had a brown complexion since I'm an asian.
