I have scars on my left foot from an accident 6 months ago. How can they be removed non-surgically? (photos)

Hello, I met with an accident last year in October where a truck passed over my left foot. It passed quite slowly so I had a lot of injury luckily including just a hairline fracture under the third toe and quite a few deep wounds. It's been 6 months and I have many spot scars on my foot which are black in colour, also my foot has blackened overall compared to my other foot. I want to get rid of the black spots. What do you suggest for such scar removal without any surgery ?
