Is there a way to remove these scars?

i have a few scars on my legs from being clumsy and falling, some are 2-3 old and others a year old. I was wondering is there any way to remove them or at least fade them? Also i was thinking of trying a skin lightening cream on them but i read that after ending using the product the skin color comes back. Could the scar come back after using the skin lightening cream on my scars?
