Solution for Dark Mosquito Bite Scars on Legs?

I came from the Philippines and as a child, I itched and scratched my mosquito bites, which resulted to many scars mainly on my legs. I have huge dark scars, some as big as a quarter. Is there a kind of scar removal that will work for me? I would love to wear skirts or pants that don't go down to my ankles without being so self-conscious someday. Thanks in advance.
