Rough Elbows?

To smooth it out, do the salt and lime trick.  Slice a lime in half and sprinkle the fleshy end with salt (or sugar if your skin is very sensitive).  Bend your arm, hold the fruit against your elbow and twist.  Do it like you're juicing the lime.  Do it for one minute then rinse. 

The fruit's citric acid will help dissolve layers of hard dry skin while the rotating action will aid the salt in  buffing away dead cells for soft elbows.
