I love Aveeno lotion for daily use and Cocoa Butter for use 1-2x a week. When I use lotion regularly, my skin looks MUCH more even and nicer. But then again, I live in a VERY dry environment (desert).
I just wanted to suggest a lotion with menthol crystals will help ya tremendously also. I make bath and body products so I've done a ton of research on this and other skin "type" factors.
Arimidex may reduce your estrogen levels moderately. It may or may not be enough to make a difference unless you are already very lean. I also hope you're not using oral contraceptives...and no ephedrine type thermogenics.
AAS combined with Arimidex and Yohimburn ES would be the most potent anti-cellulite stack you can get your hands on, though the more of these hormonal manipulations you make, the greater chance of unwanted side effects.
Try the Yohimburn ES/exercise/low GI approach first and see how far you get.
