Oxygen spray bottles. 
I'm sure there's real oxygen in here, I just don't know why.  Sure, breathing pure oxygen can be refreshing, if it doesn't make you dizzy, but a lightweight aerosol bottle like this can't contain enough to make any real difference.  One of them also contains water which is probably more responsible for the refreshing effect than the oxygen, especially if the bottle is chilled, as they suggest, before you spray it in your face.
