BBL for sun spots and chemical peel?

Im fair white skinned. I was thinking of getting the bbl for sun spots on my arms. Is that the best laser for that? Also i was wanting to improve my skin texture and do a chemical peel on them also. Would it be best to do the chemical peel before or after the bbl treatment? And how long would you have to wait before or after to do the other treatment? I was thinking peel then bbl... Am i correct? Would it help the bbl to work better? And if so how long between the two would you wait to do it?
