How do i get these dark spots off my leg?

umm..i have these dark spots on my leg..theyre flat and they almost look like freckles but just a little bit bigger..i dont really show my legs that much so is it from lack of sun or something....do u think coco butter would work?How do i get these dark spots off my leg?
if the Coco butter doesn't work then I would use some prescription skin lightening serum, this will defiantly work, if you don't want to use something so strong then maybe use some Avenno tone evening stuffHow do i get these dark spots off my leg?
yeah get like 100% coco butter put it on twice or 3 times aday..like after you shower or whenever..it does sound like lack of sun but just put coco butter on it
