Does laser hair removal make hair follicles that are dark less visible or even completely remove them? (Photo)

I get dark spots after shaving my legs and I have very fine hair on my chest. I can notice if I look closely I get black/red spots where the hair grows from on my chest. Will this go on it's own? Or will laser help get rid of them permanently or only reduce their appearance? Is there a specific laser good for this? I have a tan/olive skin type.
