What are these dark spots on my legs? (photos)

I have dark spots (mostly on legs, but a few on the body) that get darker with self tanner. I am very fair and do not get out in the sun. How can I get rid of these??? I have TONS of them. I know they can be frozen off, but is there anything else? I want to wear self tanner as I do not get in the sun, but this just makes them look more pronounced. I want them off so badly. What are the options?
