What is a good body moisturizer for acne-prone skin?

I have a good facial moisturizer and I use body butter for my arms and legs, but I need something for my back and chest. The skin in this area is prone to cystic acne so I don%26#039;t want anything that would have even the remotest possibility of plugging the pores, and definitely oil-free. The skin, especially on my back, gets pretty dry in winter. Any suggestions?|||alevera, i don%26#039;t know how to spell it, it%26#039;s a cactis.
