How do I get rid of these scrapes? And will I scar?

Okay, so basically, I’ve probably developed an allergy to mosquito bites, or I ran into some mutant mosquitoes. Without even realizing it, I scratched until I had scraped the skin enough to scab. I’ve had the damned scabs for weeks, and shaving is starting to take some of the scabs off, but my legs look horrible. Like I was attacked or something.

Why is this taking weeks to go away? They seem so superficial to still be there nearly a month later. Is there anything I can do to speed it up?
