How to get rid of scars?

A while back I started to cut my wrists but then I got help and now I'm better but the scars won't to away. They are reddish pink indents on my wrist and there's been no fading for 3 months. Please no rude responses. I just would like to know if there is something easy and affordable(even a homemade recipe?) that would help fade my scars, thx:)
