What can I do to remove/flatten/fade my self harm scars? (photos)

I would self harm using a blade. I did it quite a lot ,they vary from thin to thick, but many are pretty thin. The thing is, there are many small ones overlapped, causing my skin to wrinkle. It's been or 2 years so many have faded to a white/pinkish color. I've accepted that nothing will completely get rid of them but is there anything I can do to make them less noticeable? Something that will make them flat? Maybe like a cream or would I need to get laser treatment?
